Algorithms for detecting endotracheal intubation and/or misplacement of endotracheal tubes in child patients during anesthesia for use with anesthesia machines, mechanical ventilators, and/or respiratory function monitors. An algorithm uses end-tidal carbon dioxide (EtCO.sub.2), and tidal volume (TV) or peak inspiratory pressure (PIP) to detect exact intubation time. Another algorithm uses respiratory parameters to identify and/or confirm the type of airway device used during mechanical ventilation, and to detect if and when an issue has arisen with use of a specific airway device to provide real-time decision support to attending medical care professionals.

Systems and methods for electronically creating and modifying a fitness plan are disclosed. The method may include receiving electronic user data, collecting electronic fitness data, and displaying a suggestion for a fitness activity based on the electronic user data and the electronic fitness data.

Various systems, devices, components, and methods are disclosed for measuring the concentration of an analyte, such as acetone, in a breath sample. The disclosed devices include a breath sample analysis device having a mouthpiece configured to facilitate engagement with a user's mouth to receive a breath sample. The disclosed devices also include a breath sample capture cartridge containing an interactant that extracts the analyte from a breath sample passed through the cartridge. Also disclosed are devices for routing the breath sample through the cartridge during exhalation, and for analyzing a reaction in the cartridge to measure a concentration of the analyte.

A biofeedback headset for providing input to and receiving output from an information handling system may include a controller to send and receive audio signals to and from the information handling system and send biofeedback signals to the information handling system; one or more speakers mounted to a wearable head band to provide audio output from the information handling system to a user; and a mouthpiece operatively coupled to the wearable headband including: a microphone to receive audio input from the user; a pressure sensor to detect a breathing rate and amplitude of the user and, with the controller, provide breathing rate and amplitude biofeedback signals to the information handling system; and a gas sensor to detect a composition of air at the mouthpiece as the user respirates and, with the controller, provide air composition biofeedback signals to the information handling system.

The present invention relates to a decision support system (DSS), a medical monitoring system (100), and a corresponding method for identifying the need for measurement of cardiac output (CO) based on one or more comparisons (COMP1, COMP2) in a physiological model. More specifically, for identifying when an approximated value of CO cannot be correct due to circulatory compromise and as such that another estimated or measured value of CO is required.

A calculation device is provided with: an acquisition unit that acquires an acetone concentration in a gas constituent discharged from a user and measured; an estimation unit that estimates a calorie balance corresponding to the acetone concentration acquired by the acquisition unit based on a predetermined correlative relationship between acetone concentrations and calorie balance; and a processing execution unit that executes predetermined processing using an estimation result of the estimation unit.
