Abstract
Description
Technical Field
[0001] This invention relates to the field of medical data processing, and more particularly to clinical assessment and prediction methods and systems for exhaled breath and transcutaneous carbon dioxide monitoring. Background Technology
[0002] Arterial blood gas analysis, specifically the partial pressures of oxygen and carbon dioxide, objectively reflects the nature and severity of respiratory failure and is a reliable method for determining whether a patient has low O2 and CO2 retention. However, continuous blood gas analysis requires repeated arterial blood sampling, increasing the complexity of the process and increasing the risk of infection due to repeated invasive procedures. To facilitate continuous, non-invasive monitoring of carbon dioxide partial pressure, exhaled and transcutaneous carbon dioxide partial pressure monitoring is now widely used in clinical settings.
[0003] Currently, transcutaneous gas partial pressure monitoring (TMP) sensors are used to detect the partial pressure of gases in subcutaneous tissue. The main principle is to use electrodes with heating capabilities to increase the temperature of the subcutaneous tissue, accelerating blood flow in the subcutaneous capillaries, thereby increasing the skin's permeability to gases and thus detecting the partial pressure of gases in the subcutaneous tissue. However, currently, exhaled gas and transcutaneous carbon dioxide partial pressures need to be used simultaneously to analyze a patient's health status. This results in excessive data processing volume for gas partial pressure data and fails to provide comprehensive and accurate monitoring of the patient's potential organ and tissue metabolic status. Consequently, it cannot provide a reliable reference for clinical monitoring data processing and reduces the credibility of clinical disease risk assessment. Summary of the Invention
[0004] Unlike existing technologies that only monitor and analyze transcutaneous carbon dioxide partial pressure to identify patient vital signs and predict potential disease risks, these methods only target a single data point and cannot comprehensively reflect the patient's true physical condition. They also cannot quickly predict and assess potential health risks or improve the reliability of disease risk assessments. To fully obtain comprehensive carbon dioxide partial pressure data from patients and quickly and accurately assess their clinical disease risks, this invention provides a clinical assessment and prediction method using exhaled breath and transcutaneous carbon dioxide monitoring.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0020] Please see Figure 1 As shown, this invention provides a clinical assessment and prediction method for exhaled breath and transcutaneous carbon dioxide monitoring, the method comprising the following steps: S100: Based on the surface temperature data of the target subject, the skin temperature fluctuation characteristics are obtained, thereby determining the target skin area for transdermal carbon dioxide monitoring of the target subject; based on the transdermal carbon dioxide partial pressure of the target skin area, the transdermal carbon dioxide release characteristics are obtained. S200: Simultaneously acquire the partial pressure of exhaled carbon dioxide of the target subject to obtain the relative change relationship between transdermal carbon dioxide partial pressure and exhaled carbon dioxide partial pressure; based on the relative change relationship and transdermal carbon dioxide release characteristics, estimate the energy metabolism characteristics of the target subject; S300: Based on energy metabolism characteristics, construct a metabolic model that matches the target subject to predict the trend of disease risk changes in the target subject; S400: Based on the trend of disease risk changes, assess and screen the clinical test data of the target subjects to obtain a reliable clinical test dataset, thereby generating disease risk assessment results.
[0021] Furthermore, in S100, based on the target subject's surface temperature data, skin temperature fluctuation characteristics are obtained to determine the target skin area for transdermal carbon dioxide monitoring; based on the transdermal carbon dioxide partial pressure of the target skin area, transdermal carbon dioxide release characteristics are obtained, specifically: The global surface thermal infrared dynamic image of the target object is acquired. The global surface thermal infrared dynamic image is then segmented and transformed to determine the dynamic data of the target object's surface temperature, thereby obtaining the skin temperature change rate of the target object. Based on the rate of change in skin temperature, determine the stability of transdermal carbon dioxide release across the entire body surface area of the target subject; based on the stability of transdermal carbon dioxide release, determine the target skin area for transdermal carbon dioxide monitoring of the target subject. Transdermal carbon dioxide partial pressure data of the target skin area were collected, and time-difference variation analysis was performed on the transdermal carbon dioxide partial pressure data to obtain the transdermal carbon dioxide release rate of the target skin area, which was used as the transdermal carbon dioxide release characteristic.
[0022] Transdermal carbon dioxide (CVD) monitoring utilizes electrodes with heating capabilities to heat the skin of the target subject, increasing blood flow in the subcutaneous capillaries and thus enhancing skin permeability. This allows the gas to be released more smoothly through the subcutaneous tissue. The pressure of the released gas is then measured using electrodes to obtain the corresponding subcutaneous CCD partial pressure. As the above analysis shows, the target subject's skin temperature affects the efficiency of transdermal CCD release and diffusion; only when the transdermal CCD release and diffusion efficiency is sufficiently high can the measured transdermal CCD partial pressure be considered reliable. To ensure the reliability of transdermal carbon dioxide partial pressure detection of the target object, dynamic thermal infrared imaging is first performed on the target object to obtain a global dynamic thermal infrared image of the target object's body surface. The global dynamic thermal infrared image of the body surface is then processed by frame segmentation and transformation analysis to obtain dynamic data of the target object's body surface temperature. The aforementioned dynamic data of body surface temperature refers to the temperature change data of each grid area under the target object's skin within a preset time interval. Then, the aforementioned dynamic data of body surface temperature is analyzed for time variation to obtain the skin temperature change rate (i.e., skin temperature change rate) of each grid area under the target object's skin surface.
[0023] The above analysis shows that transdermal carbon dioxide can only be effectively and continuously released and diffused when the target subject's skin temperature remains consistently high. Only under these conditions can the transdermal carbon dioxide partial pressure be monitored reliably. Therefore, it is necessary to compare the skin temperature change rate of each grid region with a threshold to determine whether the transdermal carbon dioxide release in each grid region is stable. Specifically, the skin temperature change rate of each grid region is compared with a preset change rate threshold. If the skin temperature change rate is less than the preset change rate threshold, the transdermal carbon dioxide release of the corresponding grid region is determined to be stable; otherwise, the transdermal carbon dioxide release of the corresponding grid region is determined to be unstable. Thus, all grid regions with stable transdermal carbon dioxide release are identified as the target skin regions for transdermal carbon dioxide monitoring of the target subject. This ensures that the target skin region is monitored for transdermal carbon dioxide partial pressure only under suitable subcutaneous tissue temperature conditions, guaranteeing the reliability of the transdermal carbon dioxide partial pressure data.
[0024] Transdermal carbon dioxide partial pressure data for each target skin region is collected using a transdermal carbon dioxide partial pressure sensor. It can be understood that the transdermal carbon dioxide partial pressure data is directly proportional to the transdermal carbon dioxide release volume data. By performing time difference variation analysis on the transdermal carbon dioxide partial pressure data, the transdermal carbon dioxide release rate (i.e., the volume of transdermal carbon dioxide released per unit time in each target skin region) can be obtained.
[0025] Furthermore, in S200, the exhaled carbon dioxide partial pressure of the target subject is simultaneously acquired to obtain the relative change relationship between the transdermal carbon dioxide partial pressure and the exhaled carbon dioxide partial pressure; based on the relative change relationship and the transdermal carbon dioxide release characteristics, the energy metabolism characteristics of the target subject are estimated, specifically: Based on the sampling frequency of transcutaneous carbon dioxide partial pressure, the exhaled carbon dioxide partial pressure of the target subject is acquired synchronously; the transcutaneous carbon dioxide partial pressure and the exhaled carbon dioxide partial pressure are continuously compared to obtain the curve of the difference between the transcutaneous carbon dioxide partial pressure and the exhaled carbon dioxide partial pressure. Based on the difference change curve, the dynamic characteristics of organ and tissue blood flow of the target object are estimated; based on the dynamic characteristics of organ and tissue blood flow and the transdermal carbon dioxide release characteristics, the energy metabolism characteristics of the target object are estimated; among them, the organ energy metabolism characteristics include the energy metabolism rate of organ and tissue.
[0026] Exhaled carbon dioxide refers to the carbon dioxide contained in the gas exhaled during human respiration. Considering the cyclical nature of respiration, and focusing on the exhalation process, it mainly includes the initiation phase, the ascending phase, the plateau phase, and the end phase. In the initiation phase, the exhaled gas consists of dead space gas in the respiratory tract and generally does not contain carbon dioxide. In the ascending phase, the gas is a mixture of dead space gas and alveolar gas; as exhalation progresses, the proportion of alveolar gas increases, and the carbon dioxide concentration in the exhaled mixture increases rapidly. The plateau phase is almost horizontal, with the exhaled gas consisting of alveolar gas with a high concentration of carbon dioxide, and the carbon dioxide partial pressure is at its highest. The end phase is the descending phase of inspiration, a steep drop to the baseline level, representing the start of inspiration, and the carbon dioxide concentration drops sharply to zero. Exhaled carbon dioxide can reflect cardiac output and pulmonary perfusion. Therefore, the partial pressure of exhaled carbon dioxide also reflects the functioning of organs and tissues such as the heart and lungs. Thus, comprehensive and accurate measurement of exhaled carbon dioxide partial pressure is of great significance for the targeted determination of energy metabolism and other operational parameters of organs and tissues.
[0027] When a target subject is potentially developing conditions such as pulmonary embolism, a difference will exist between the exhaled and transcutaneous partial pressures of carbon dioxide, and this difference will gradually increase as the condition progresses. Specifically, by continuously comparing the transcutaneous and exhaled carbon dioxide partial pressures, a curve showing the change in the difference between the two pressures is obtained. Based on this curve, the dynamic characteristics of organ and tissue blood flow in the target subject are estimated. It is understandable that when organs such as the heart or lungs have underlying conditions, the blood flow velocity within these organs and tissues decreases. At this time, the percutaneous carbon dioxide partial pressure increases while the exhaled carbon dioxide partial pressure decreases. This difference gradually widens, primarily reflecting a slowdown in the organ's energy metabolism. Based on this analysis, the dynamic characteristics of organ blood flow in the target subject are estimated using the difference curve. Furthermore, the energy metabolism rate of organs such as the heart or lungs is estimated based on these dynamic characteristics and the percutaneous carbon dioxide release characteristics. A convolutional neural network model can be used to process these dynamic characteristics and the percutaneous carbon dioxide release characteristics to obtain the organ's energy metabolism rate, which will not be detailed here.
[0028] Furthermore, in S300, a metabolic model matching the target subject is constructed based on energy metabolism characteristics to predict the trend of disease risk changes in the target subject, specifically as follows: Based on the energy metabolism characteristics, including the energy metabolism rate of organs and tissues and the theoretical metabolic model of organs and tissues, construct an actual metabolic model of organs and tissues that matches the target object; Based on the time evolution analysis results of the actual metabolic model of organs and tissues, the trend of organ and tissue disease risk changes of the target subjects is predicted; among them, the trend of organ and tissue abnormality risk changes includes the trend of the probability of organ and tissue disease occurrence.
[0029] Different types of organs and tissues, such as the heart and lungs, have different physiological structures and functions, resulting in different energy metabolism profiles. These profiles include the organ and tissue energy metabolism rate and the theoretical metabolic model (i.e., the energy consumption model for maintaining basic normal function in a local tissue). To accurately characterize the metabolism of different organs and tissues, an actual metabolic model of the target organ and tissue is constructed based on the organ and tissue energy metabolism rate and the theoretical metabolic model. This ensures that the actual metabolic model is consistent with the corresponding organ and tissue. Furthermore, time-evolution analysis is performed using the actual metabolic model to predict the energy metabolism trend of organs and tissues over a future period. If a sudden event occurs in the energy metabolism of an organ or tissue (such as a sudden drop or increase in the energy metabolism rate) in the future, the predicted probability of organ and tissue disease risk for the target individual will increase. Conversely, if no sudden event occurs (such as a relatively stable energy metabolism rate), the predicted probability of local tissue disease risk for the target individual is low. The model also identifies the time range within which the probability of organ and tissue disease risk exceeds a preset probability threshold, providing a basis for subsequent evaluation and screening of clinical test data.
[0030] Furthermore, in S400, based on the changing trends of disease risk, the clinical testing data of the target subjects are evaluated and screened to obtain a reliable clinical testing dataset, thereby generating disease risk assessment results, specifically: Based on the trends in disease risk, including the trends in the probability of occurrence of organ and tissue diseases, a credible time interval for conducting clinical tests on the target subjects is determined; based on the credible time interval, the clinical test data of the target subjects are evaluated and screened to obtain a credible clinical test dataset. Clustering and predictive analysis are performed on reliable clinical test datasets to generate disease risk assessment results.
[0031] This study extracts the probability trends of organ and tissue disease risk changes. Based on these trends, it determines the time range within which the probability of an organ or tissue disease exceeding a preset probability threshold is expected. Extending this extended time range forward and backward by a certain time length from the earliest and latest points of this range, it establishes a reliable time interval for clinical testing of the target subject. Then, using this reliable time interval as a benchmark, the clinical testing data from the target subject is filtered, extracting only data generated within this reliable time interval. This extracted data forms a reliable clinical testing dataset. A neural network model (such as an LSTM network model) is then used to perform clustering and predictive analysis on the reliable clinical testing dataset to generate disease risk assessment results. These results may include information such as the type of disease the target subject may have and the stage of disease onset.
