Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a monitoring device, a monitoring system, and a method for monitoring energy supply. Background Technology

[0002] Nutritional support therapy should be considered for all inpatients in the Intensive Care Unit (ICU), especially those hospitalized for more than 48 hours. The goals of nutritional support are: 1. to provide energy and nutrients to maintain organ function; 2. to regulate immunity through the pharmacological effects of nutrients; and 3. to reduce protein breakdown and prevent complications. Inappropriate nutritional support strategies can lead to malnutrition, including both undernutrition and overnutrition. Undernutrition in critically ill patients can lead to ventilator dependence, increased risk of infection, and higher mortality; overnutrition can cause hypercapnia and fat accumulation. Therefore, precise control of nutritional support and dosage is crucial for critically ill patients in the ICU or other departments.

[0003] Currently, the implementation results of nutritional support in clinical practice are not optimistic. Studies have found that 50% of ICU patients are malnourished, with 14.7% suffering from severe malnutrition. Furthermore, among critically ill ICU patients over 75 years of age, the malnutrition rate reaches 65%; for patients with malignant tumors, this rate is 85%; and for respiratory patients, it is 45%. The current state of clinical nutritional support is largely attributed to the inability of physicians to easily compare patients' energy expenditure with actual energy supply. For example, for mechanically ventilated patients, physicians often do not use standard indirect calorimetry to calculate energy metabolism; they merely estimate energy expenditure and then develop nutritional support strategies based on experience. Nurses, when providing nutritional support to critically ill mechanically ventilated patients, can only manually calculate the energy and nutrient supply, which is highly inaccurate.

[0059] It should be understood that, Figure 1 This is merely an example of the components included in the monitoring device 100 and does not constitute a limitation on the monitoring device 100. Furthermore, the monitoring device 100 may include components beyond those specified in the original text. Figure 1 The monitor may include more or fewer components, or a combination of certain components, or different components. For example, the monitor 100 may also include a power module, a positioning and navigation device, a printing device, etc.

[0060] To monitor the metabolic status of the target subject during nutrient infusion in real time, the processor 120 of the monitoring device 100 acquires the energy consumption and energy supply of the target subject during nutrient infusion, and provides information reflecting the relative relationship between energy consumption and energy supply to the user to assist the user in formulating or adjusting a nutrient support strategy. Specifically, the processor 120 can control the display 130 to output information related to energy consumption and energy supply; or, the processor 120 can obtain nutrient support-related information of the target subject based on energy consumption and energy supply within a preset time period, and provide nutrient support-related information.

[0061] The target patient can be a mechanically ventilated patient or any patient receiving nutritional infusion. Nutritional infusion is provided by an infusion pump, including an infusion pump or a syringe pump. When the target patient is a mechanically ventilated patient, nutritional infusion can be enteral nutrition, provided by a dedicated enteral nutrition support infusion pump; it can also be parenteral nutrition. Exemplarily, the monitoring device 100 is communicatively connected to the infusion pump providing nutritional infusion to the target patient to obtain relevant information about the nutritional infusion from the infusion pump. Providing nutritional infusion to the target patient includes providing the target patient with at least one of the following nutrients: protein, fat, and carbohydrates.

[0062] The processor 120 of the monitoring device 100 acquires the energy supply provided to the target subject during nutrient infusion. The energy supply acquired by the processor 120 may include the real-time energy supply to the target subject, or the cumulative energy supply over a preset time period. The energy supply may be the energy supply of at least one nutrient among all nutrients ingested by the target subject, or the total energy supply of all nutrients ingested by the target subject.

[0063] In one embodiment, the monitoring device 100 acquires energy supply information during nutrient infusion to the target object via a communication interface, and then determines the energy supply amount for nutrient infusion to the target object based on the energy supply information. Alternatively, the monitoring device 100 acquires the energy supply amount during nutrient infusion to the target object via a communication interface. Specifically, the monitoring device 100 acquires energy supply information or energy supply amount from the infusion pump providing nutrient infusion via a communication interface, either wired or wirelessly.

[0064] The energy supply information includes the flow rate, volume, and composition of the nutrient solution. The infusion pump sends this energy supply information to the monitoring device 100, which can calculate the energy supply amount based on this information. Specifically, this includes at least one of the energy supply amount for each nutrient and the total energy supply amount for all nutrients. For example, the energy supply amount for each nutrient can be obtained based on its mass and unit energy supply; the total energy supply amount can be obtained by summing the energy supply amounts for all nutrients.

[0065] Optionally, the infusion pump can calculate the energy supply amount based on the energy supply information and send it to the monitoring device 100. The processor 120 of the monitoring device 100 directly obtains the energy supply amount calculated and output by the infusion pump based on the energy supply information, specifically including at least one of the energy supply amounts of each nutrient and the total energy supply amount. The processor 120 can also obtain the energy supply amount of the nutrient infusion through other means, such as receiving the energy supply amount input by the user.

[0066] The processor 120 is also used to acquire the energy consumption of the target object. The energy consumption acquired by the processor 120 can be the real-time energy consumption of the target object, or the cumulative energy consumption over a preset time period; it can be the energy consumption of at least one nutrient among all nutrients ingested by the target object, or the total energy consumption of all nutrients ingested by the target object. For example, when the energy supply acquired by the processor 120 includes the energy supply of protein, the corresponding energy consumption will at least include the energy consumption of protein; when the energy supply includes the total energy supply of all nutrients, the energy consumption will at least include the total energy consumption of all nutrients.

[0067] For example, the processor 120 can acquire metabolic-related parameters of the target object in real time and calculate the energy consumption of the target object based on the metabolic-related parameters. Specifically, the processor 120 can obtain data on metabolic-related parameters that can be used to determine energy consumption from the data on the target object's vital signs stored in the memory 110, analyze the data on metabolic-related parameters, and calculate the energy consumption of the target object.

[0068] For example, the processor 120 can use indirect calorimetry to calculate the energy consumption of the target object. In general chemical reactions, there is a certain proportional relationship between the amount of reactants and the amount of products. This basic principle is also seen in the oxidation of nutrients for energy in the human body. The basic principle of indirect calorimetry is to use this proportional relationship to calculate the energy consumption of all nutrients in the human body over a certain period of time, as well as the energy consumption of various nutrients such as sugar, fat, and protein. When indirect calorimetry is used, the metabolic parameters of the target object used to calculate the energy consumption include the amount of oxygen consumed, the amount of carbon dioxide generated, and the amount of urinary nitrogen excreted by the target object within a preset time period.

[0069] Specifically, the human body relies on respiration to take in oxygen from the outside world to meet the needs of the oxidation and decomposition of various nutrients, while simultaneously exhaling the metabolic product CO2. The ratio of CO2 production to oxygen consumption within a certain time period is called the respiratory quotient. The ratio of CO2 production to oxygen consumption for various nutrients is called the respiratory quotient of that nutrient. For ease of calculation, the ratio of the volume of CO2 to O2 is usually used. The CO2 production and oxygen consumption differ when carbohydrates, fats, and proteins are oxidized, resulting in different respiratory quotients for each. Carbohydrates consume an equal number of O2 molecules and produce an equal number of CO2 molecules during oxidation, resulting in a respiratory quotient of approximately 1. Fat oxidation requires more oxygen, therefore its respiratory quotient is less than 1, approximately 0.71. Proteins cannot be completely oxidized in the body; therefore, the respiratory quotient of proteins needs to be indirectly calculated from the O2 and CO2 production required when the carbon and hydrogen in protein molecules are oxidized, resulting in a respiratory quotient of approximately 0.80.

[0070] Indirect calorimetry utilizes the respiratory quotient of various nutrients to calculate their energy consumption. To calculate the body's energy consumption, it is first necessary to determine the amount of protein oxidation. The O2 consumed and CO2 produced by protein oxidation are then subtracted from the total oxygen consumption and total CO2 production. The ratio of CO2 production to oxygen consumption from carbohydrate and fat oxidation (i.e., non-protein metabolism), known as the non-protein respiratory quotient, is then calculated. Finally, the individual oxidative breakdown amounts of carbohydrates and fats are calculated.

[0071] Since nitrogen in urine is primarily a product of protein breakdown, and the nitrogen (N) from protein is completely excreted in urine, the amount of protein oxidized and broken down in the body can be determined by the amount of urinary nitrogen and the proportion of N in protein. This allows us to derive the energy expenditure (heat production) of protein, the oxygen consumption required for protein oxidation, and the CO2 production generated by protein oxidation. Subtracting the oxygen consumption and CO2 production of protein from the total oxygen consumption and CO2 production yields the oxygen consumption and CO2 production of non-protein nutrients (carbohydrates and fats). The ratio of these two values ​​is the non-protein respiratory quotient. Based on the non-protein respiratory quotient, the corresponding oxygen calorific value can be obtained, allowing us to calculate the heat production from non-protein metabolism. The total energy expenditure of all nutrients is the sum of the energy expenditure from protein metabolism and the energy expenditure from non-protein metabolism. Furthermore, the proportion of carbohydrates and fats involved in metabolism can be deduced from the non-protein respiratory quotient, allowing us to calculate the energy expenditure of each.

[0072] It should be noted that the above process for calculating energy consumption is only an example, and the monitoring device 100 can also use any other suitable method to obtain the energy consumption of the target object. For example, a simplified indirect calorimetry method can be used to calculate the respiratory quotient based on the total oxygen consumption and CO2 production over a period of time, find the oxygen calorific value corresponding to the respiratory quotient, and multiply the oxygen calorific value by the oxygen consumption to estimate the total energy consumption.

[0073] For example, processor 120 can use a prediction method to obtain the energy consumption of the target object. Processor 120 can calculate the energy consumption of all nutrients in the human body over a certain period of time, as well as the energy consumption of each nutrient, based on the Harris-Benedict equation. When using the prediction method, processor 120 can calculate the energy consumption of the target object based on its vital signs information, using the Harris-Benedict equation. The vital signs information of the target object includes height, weight, age, and gender.

[0074] For example, the processor 120 directly acquires metabolic-related parameter data of the target object associated with the monitoring device; that is, the processor 120 obtains the metabolic-related parameter data of the target object through the sensors of the monitoring device 100 itself. The monitoring device can perform preprocessing such as interference suppression, signal filtering, and amplification on the signals collected by the sensors to finally obtain real-time data of the metabolic-related parameters of the target object, and can store the real-time data of the metabolic-related parameters obtained within a preset time period in the memory 110. Of course, the vital sign parameter data acquired by the monitoring device 100 can also include data of conventional monitoring parameters, such as heart rate, electrocardiogram, arterial pressure, respiratory rate, central venous pressure, etc., and can also include data of other vital sign parameters, without specific limitations.

[0075] Alternatively, the processor 120 can acquire ventilation parameter data from the ventilation device connected to the target object to obtain data on the target object's metabolic-related parameters. Specifically, the monitoring device 100 can be communicatively connected to the ventilation device that provides mechanical ventilation to the target object; the processor 120 can acquire the target object's oxygen consumption and carbon dioxide production from the ventilation device.

[0076] After obtaining the energy consumption and energy supply, the processor 120 can control the output of a metabolic interface on the display 130, and simultaneously output the energy supply and energy consumption of the target object at the same time on the metabolic interface. Users can compare the energy supply and energy consumption at the same time, thereby helping users to formulate nutritional support strategies for the target object more conveniently and accurately.

[0077] The energy expenditure displayed on the metabolic interface includes the energy expenditure of at least one nutrient, and the energy supply includes the energy supply of at least one nutrient. Energy expenditure and energy supply correspond to the same nutrient. See also Figure 2 The energy consumption and energy supply of at least one nutrient include the energy consumption and energy supply of protein, carbohydrates, and fats. The processor 120 can control the output of the energy consumption and energy supply of the same nutrient within a preset time period in the form of a trend graph on the metabolic interface. The trend graphs of energy consumption and energy supply for the same nutrient are plotted on the same coordinate system to facilitate comparative analysis of the energy consumption and energy supply for each nutrient. For example, the trend graph can also include baselines corresponding to the upper and lower limits of energy consumption and energy supply to help the user determine whether the energy consumption is within the allowable range.

[0078] Of course, the processor 120 can also present the energy consumption and energy supply of at least one nutrient in other ways, including but not limited to bar charts, tables, etc., as long as the relative relationship between the energy consumption and energy supply of each nutrient can be presented.

[0079] The energy consumption displayed on the metabolic interface can also include the total energy consumption of all nutrients, and correspondingly, the energy supply includes the total energy supply of all nutrients. The processor 120 can control the display 130 to output the total energy consumption and total energy supply of all nutrients within a preset time period in the metabolic interface in the form of a trend graph. Figure 2 The trend charts of total energy consumption and energy supply for all nutrients are plotted above the trend charts of energy consumption and energy supply for different nutrients, and they all share the same time axis to facilitate comparative analysis.

[0080] Furthermore, the processor 120 can calculate the total energy accumulation of all nutrients for the target object within a preset time period based on the total energy consumption and energy supply of all nutrients, and control the output of the total energy accumulation of all nutrients on the metabolism interface. The energy accumulation can intuitively indicate whether the target object is malnourished or malnourished, making it easier for users to determine whether the current nutritional support strategy is appropriate. In one example, the processor 120 can also calculate the total energy accumulation of each nutrient for the target object within a preset time period based on the energy consumption and energy supply of different nutrients, and control the output of the energy accumulation of each nutrient on the metabolism interface.

[0081] For example, the display of accumulated energy can also include quantitative numerical displays. The display of accumulated energy can also include graphical displays, specifically including but not limited to bar charts. See also... Figure 2 , Figure 2 The graph displays the total energy accumulation of all nutrients and the energy accumulation of carbohydrates, fats, and proteins, with the height of the bars representing the magnitude of the energy accumulation. The energy accumulation of proteins, carbohydrates, and the total energy accumulation of all nutrients are positive, meaning energy supply exceeds energy expenditure; therefore, the bars are plotted above the baseline. The energy accumulation of fat is negative, meaning energy supply is less than energy expenditure; therefore, the bars are plotted below the baseline. For example, the processor 120 can also control the display of positive and negative energy accumulations in a differentiated manner, such as displaying them in different colors.

[0082] For example, the preset time period can coincide with the time period for displaying energy consumption and energy supply. When the energy consumption and energy supply displayed on the metabolism interface are the energy consumption and energy supply over a 24-hour period, the energy accumulation can be the energy accumulation over a 24-hour period. The processor 120 can also adjust the aforementioned preset time period for displaying energy consumption, energy supply, and energy accumulation in response to user input commands. For example, Figure 2 The trend charts of energy consumption and energy supply for each nutrient and the bar charts of energy accumulation in the metabolic interface shown correspond to the preset time period of the previous 24 hours. Users can adjust them to other time periods such as 12 hours and 48 hours.

[0083] In one embodiment, the processor 120 can also determine whether the cumulative energy of each nutrient exceeds the allowable range, and display the cumulative energy of each nutrient within and outside the allowable range in a distinguishable display manner to draw the user's attention. For example, for the cumulative energy outside the allowable range, prompts can be made by changing colors, changing text, flashing graphics, adding prompts, etc.

[0084] Furthermore, the processor 120 is also used to receive the disease pattern of the target object and determine whether the energy accumulation of each nutrient or the total energy accumulation exceeds the allowable range based on the disease pattern, thereby adapting to the special nutritional or energy requirements of patients with specific diseases. Specifically, the allowable range for the energy accumulation of at least one nutrient differs under different disease patterns. For example, Figure 2 The preset thresholds in the metabolism interface shown are for patients with acute kidney injury (AKI). For AKI patients, there are specific recommended ranges for protein intake. When a user selects a specific disease in the metabolism interface, the thresholds for each nutrient will change accordingly.

[0085] In some embodiments, the processor 120 may also control the display of metabolic-related parameter data on the metabolic interface. The displayed metabolic-related parameters include part or all of the amount of oxygen consumed, carbon dioxide generated, and urinary nitrogen excreted by the target subject. (Continue referring to...) Figure 2 This displays the current carbon dioxide generation and flow rate, oxygen consumption and flow rate of the target object.

[0086] For example, the metabolic interface described above can be displayed simultaneously with the main monitoring interface of the monitoring device 100. For instance, the metabolic interface can be an area embedded in the main monitoring interface and displayed alongside the real-time parameter display area; or it can be a pop-up interface floating on the main monitoring interface, covering or not covering the content displayed in the real-time parameter display area. Alternatively, the metabolic interface and the main monitoring interface can be displayed in a switchable manner. For example, the main monitoring interface displays an identifier indicating the metabolic interface, and when a selection instruction for this identifier is received, the interface switches from the main monitoring interface to the metabolic interface. Alternatively, the monitoring device 100 can also automatically control the switching from the main monitoring interface to the metabolic interface, for example, when nutrient infusion to the target object is detected. The main monitoring interface is used to display real-time data of at least one physiological characteristic parameter of the target object, specifically including waveforms and real-time parameter values ​​of at least one physiological characteristic parameter.

[0087] In some embodiments, after obtaining the energy consumption and energy supply of the target object, the processor 120 can calculate the nutritional support status of the target object based on the energy consumption and energy supply within a preset time period, and obtain the nutritional support result based on the nutritional support status of the target object. The nutritional support result can be used to assist the user in formulating a nutritional support strategy.

[0088] The nutritional support result refers to the judgment result obtained by the processor 120 based on the nutritional support status or the action performed. For example, the processor 120 obtains the nutritional support result based on the nutritional support status, including: if the processor 120 determines that there is an abnormality in the nutritional support status, it displays a prompt message and / or issues an alarm on the display of the monitoring device 100.

[0089] The abnormality in nutritional support status includes: if at least one of the target object's cumulative energy consumption, cumulative energy supply, and the difference between cumulative energy consumption and cumulative energy supply within a preset time period exceeds a corresponding preset threshold, then a judgment result indicating an abnormality in nutritional support status will be output; and / or if at least one of the target object's real-time monitored energy consumption, energy supply, and the difference between energy consumption and energy supply exceeds a corresponding preset threshold, then a judgment result indicating an abnormality in nutritional support status will be output.

[0090] In some embodiments, the monitoring device 100 is configured with different disease modes, and the monitoring device 100 operates with different preset thresholds under these different disease modes. For patients with certain specific diseases, there are specific requirements for the supply of nutrients or energy. For example, for patients with acute kidney injury (AKI), guidelines provide clear recommendations for protein intake. Therefore, when the monitoring device 100 is set to operate in a certain disease mode, it automatically adopts the preset thresholds for nutrients and energy corresponding to that disease, thereby enabling the monitoring device 100 to better meet the specific nutritional support requirements of different diseases.

[0091] For example, the prompt information displayed by processor 120 includes the name of the illegally ingested nutrient and the details of the illegal intake. The prompt information can be displayed on the metabolism interface described above, for example... Figure 2 The "Excessive Protein Intake" message displayed in the upper right corner of the metabolism interface is an example of such a warning. Showing the names of the improperly ingested nutrients and the details of the improper intake helps users adjust their nutrient intake levels promptly.

[0092] In some embodiments, when an abnormality in nutritional support is detected, the processor 120 further performs the following action: issuing an instruction to adjust the nutrient infusion to adjust the energy supply to the target object. For example, when the processor 120 detects an abnormality in nutritional support, it can issue a control instruction to adjust the flow rate of the nutrient infusion and send the control instruction to the infusion pump via a communication interface, so that the infusion pump controls the flow rate of the nutrient solution in response to the flow rate control instruction. This enables timely control of the nutrient solution flow rate according to the nutritional support status, achieving intelligent management of nutrient infusion.

[0093] In summary, the monitoring device 100 of this embodiment of the invention automatically acquires the energy consumption and energy supply of the target object during the nutrient infusion process, and outputs relevant information on nutrient support, thereby assisting the user in formulating or adjusting nutrient support strategies.

[0094] This invention also provides a monitoring system. See [link to relevant documentation]. Figure 3 , Figure 3 A structural block diagram of a monitoring system 300 according to an embodiment of the present invention is shown. The monitoring system 300 of the present invention includes a monitoring device 310 and an infusion pump 320, the infusion pump 320 being used to provide energy supply to a target object; the monitoring device 310 is communicatively connected to the infusion pump 320 to obtain the energy supply amount or energy supply information during nutrient infusion from the infusion pump.

[0095] Exemplarily, the communication connection between the monitoring device 310 and the infusion pump 320 includes a wired connection or a wireless connection; in some embodiments, the monitoring device 310 and the infusion pump 320 can be interconnected via BeneLink to enable data communication between them. The infusion pump 320 provides the monitoring device 310 with the energy supply amount or energy supply information during nutrient infusion via the communication connection. Exemplarily, the monitoring device 310 can also issue an instruction to the infusion pump 320 to adjust the nutrient infusion when it determines that the nutritional support status of the target object is abnormal, thereby controlling the infusion pump 320 to adjust the energy supply amount of the target object.

[0096] The monitoring device 310 in the monitoring system 300 of this embodiment can be implemented as the monitoring device 100 described above. For details, please refer to the above and will not be repeated here.

[0097] The following reference Figure 4 This invention also provides an energy supply monitoring method 400, comprising the following steps:

[0098] In step S410, the energy supply amount is obtained when nutrient infusion is performed on the target object associated with the monitoring device. In this step, the energy supply amount can be obtained directly from the device providing nutrient infusion, or the energy supply information can be obtained from the device providing nutrient infusion and then the energy supply amount can be calculated based on the energy supply information.

[0099] In step S420, data of the vital signs parameters of the target object are obtained, including metabolic-related parameters that can be used to determine energy consumption;

[0100] In step S430, the data of the metabolic-related parameters are analyzed to calculate the energy consumption of the target object;

[0101] In step S440, a metabolic interface is output, and the energy supply and energy consumption of the target object at the same time are simultaneously output on the metabolic interface.

[0102] For example, energy consumption includes the energy consumption of at least one nutrient, and energy supply includes the supply of at least one nutrient. The method further includes: controlling the output of the energy consumption and energy supply of the same nutrient in at least one nutrient within a preset time period in the form of a trend graph on the metabolic interface.

[0103] For example, the energy consumption includes the energy consumption of at least one nutrient, and the energy supply includes the energy supply of at least one nutrient. The method further includes: calculating the cumulative energy of each nutrient of the target object within a preset time period based on the energy consumption and energy supply of the same nutrient among at least one nutrient within a preset time period, and controlling the output of the cumulative energy of each nutrient at the metabolic interface.

[0104] For example, the method further includes: determining whether the energy accumulation of each nutrient exceeds the allowable range, and displaying the energy accumulation of each nutrient within and outside the allowable range in a distinguishable display manner.

[0105] For example, the method further includes: receiving the disease pattern of the target object, and determining whether the energy accumulation of each nutrient exceeds the allowable range based on the disease pattern; wherein the allowable range of energy accumulation of at least one nutrient is different under different disease patterns.

[0106] For example, energy consumption includes the total energy consumption of all nutrients, and energy supply includes the total energy supply of all nutrients. The method further includes: controlling the output of the total energy consumption of all nutrients and the total energy supply of all nutrients in a preset time period in the form of a trend graph on the metabolic interface.

[0107] For example, energy consumption includes the total energy consumption of all nutrients, and energy supply includes the total energy supply of all nutrients. The method further includes: calculating the total energy accumulation of all nutrients in the target object within the preset time period based on the total energy consumption and total energy supply of all nutrients within the preset time period, and controlling the output of the total energy accumulation of all nutrients at the metabolic interface.

[0108] The energy supply monitoring method 400 of this invention can be implemented in the monitoring device 100 described above. Further details can be found above and will not be repeated here. The energy supply monitoring method 400 of this invention simultaneously outputs the energy supply and energy consumption of the target object through a metabolic interface, which can assist users in formulating nutritional support strategies.

[0109] The following reference Figure 5 This invention also provides an energy supply monitoring method 500, comprising the following steps:

[0110] In step S510, the energy consumption of the target object associated with the monitoring device is obtained;

[0111] In step S520, the energy supply of the infusion pump to the target object is obtained;

[0112] In step S530, the nutritional support status of the target subject is calculated based on energy consumption and energy supply.

[0113] In step S540, the nutritional support status of the target object is calculated based on the energy consumption and energy supply within a preset time period.

[0114] In step S550, the nutritional support results are obtained based on the nutritional support status.

[0115] For example, calculating the nutritional support status of a target subject based on energy consumption and energy supply within a preset time period includes: obtaining energy consumption and energy supply within a preset time period; and calculating the difference between energy consumption and energy supply within the preset time period to obtain the nutritional support status of the target subject.

[0116] For example, the method further includes: obtaining the real-time energy consumption of the target object and / or obtaining the cumulative energy consumption within a preset time period; or obtaining the energy consumption of at least one nutrient among all nutrients ingested by the target object in real time; or obtaining the total energy consumption of all nutrients ingested by the target object in real time.

[0117] For example, the method further includes: acquiring metabolic-related parameters of the target object in real time; and calculating the energy consumption of the target object based on the metabolic-related parameters.

[0118] For example, the metabolic parameters of the target object include the amount of oxygen consumed and the amount of carbon dioxide generated by the target object; optionally, the metabolic parameters of the target object also include the amount of urinary nitrogen excreted by the target object.

[0119] For example, the method further includes: directly acquiring data on metabolic-related parameters of the target object associated with the monitoring device; or acquiring ventilation parameters on the ventilation device associated with the target object to obtain data on metabolic-related parameters of the target object.

[0120] For example, the monitoring device obtains the energy supply amount or energy supply information during nutrient infusion from the infusion pump through a communication interface; wherein, the monitoring device directly obtains the energy supply amount calculated and output by the infusion pump based on the energy supply information; or obtains the energy supply information provided by the infusion pump and calculates the energy supply amount based on the energy supply information.

[0121] For example, obtaining nutritional support results based on nutritional support status includes: if the nutritional support status is abnormal, displaying a prompt message and / or issuing an alarm on the monitor of the monitoring device. For example, the prompt message includes the name of the illegally ingested nutrient and the details of the illegal intake. Further, if the nutritional support status is abnormal, the method further includes: issuing an instruction to adjust nutritional infusion to adjust the energy supply of the target subject.

[0122] The abnormality of nutritional support status includes: if at least one of the target object's cumulative energy consumption, cumulative energy supply, and the difference between cumulative energy consumption and cumulative energy supply exceeds the corresponding preset threshold within a preset period, then the judgment result of abnormal nutritional support status will be output; and / or if at least one of the target object's real-time monitored energy consumption, energy supply, and the difference between energy consumption and energy supply exceeds the corresponding preset threshold, then the judgment result of abnormal nutritional support status will be output.

[0123] For example, the monitoring device is equipped with different disease modes, and the monitoring device has different preset thresholds when running in different disease modes.

The energy supply monitoring method 500 of this invention calculates the nutritional support status of the target object based on the energy consumption and energy supply during the nutrient infusion process.
