A method and system for managing mechanical ventilation of patients with respiratory disorders is described. The main objective of the system is to generate executable instructions for patient care which take into account a large number of parameters of patient condition and ventilation. Data regarding the state of the patient are stored in a database. Patient data are processed according to a set of protocols which contain rules for patient care decisions arranged in a logical sequence to generate detailed, executable instructions for patient care. Instructions are updated when new data are entered into the database. The data can be acquired in an automated fashion, or the clinician can be instructed to collect and enter new data into the clinical database. Likewise, patient care instructions can be carried out automatically or manually, but it is preferred that instructions are carried out manually as a safety check. The preferred embodiment of the invention includes a computer system, software for processing patient data, and a display device for presenting patient care instructions to the clinician. The system maintains a record of patient data, patient care instructions, whether instructions were followed by the clinical staff, and if not, a reason why.

A user's personal biometric information such as age, sex, weight, height as well as the user's lifestyle information, such as daily caloric input, job description, smoker status and physical fitness, is uploaded onto a host computer. Target heart rate, energy and/or caloric consumption levels related to desired fitness and weight loss goals for a particular individual are then selected having regard to fitness levels for an individual of comparable age, and consuming similar calories are then downloaded to a caloric monitoring unit. The caloric monitoring unit is provided for measuring the user's heart rate and dynamic energy and/or caloric expenditure over one to four weeks. The caloric monitoring unit includes a heart rate monitor, a unit accelerometer, a global positioning system (GPS), and an audio and/or video output. The audio/video output is operable to provide information and/or motivational prompts to the user in the event the heart rate, energy expenditure and/or caloric expenditure falls below or exceeds pre-selected target expenditures over a particular time segment of the selected time period having regard to the calories which are consumed. A display provides a continuously updated visual indication of whether or not the use has achieved the pre-selected optimum caloric burn or energy expenditure for that particular time segment. An internal calendar/clock, a processor and/or memory in the caloric monitoring unit compares measured heart rate and energy expenditures for multiple time segments against target levels stored as the user-specific fitness programme tailored to achieve the desired weight loss. The comparison is then used to generate compliance output data to either the user and/or a nutritionist.

The invention provides a system for measuring respiratory rate (RR) from a patient. The system includes an impedance pneumography (IP) sensor, connected to at least two electrodes, and a processing system that receives and processes signals from the electrodes to measure an IP signal. A motion sensor (e.g. an accelerometer) measures at least one motion signal (e.g. an ACC waveform) describing movement of a portion of the patient's body to which it is attached. The processing system receives the IP and motion signals, and processes them to determine, respectfully, frequency-domain IP and motion spectra. Both spectra are then collectively processed to remove motion components from the IP spectrum and determine RR. For example, during the processing, an algorithm determines motion frequency components from the frequency-domain motion spectrum, and then using a digital filter removes these, or parameters calculated therefrom, from the IP spectrum.
