An electronic device, method, and computer-readable recording medium execute a customizable physiological measurement schedule for measuring one or more physiological parameters of a patient. A display displays information related to the patient including physiological data, and a memory is configured to store one or more programs. The one or more processors execute the one or more programs to provide a graphical user interface (“GUI”) on the display including a customizable measurement schedule. An input is received directed to one or more measurement times and corresponding measurement intervals of the one or more physiological parameters to the customizable measurement schedule using a first selection. When the customizable measurement schedule is executed, the one or more programs when executed by the one or more processors provide a first visible indication as each measurement time and corresponding measurement interval of the customizable measurement schedule is completed.

A gas analyzer for measuring a respiratory gas component includes an emitter that emits two different wavelengths of infrared (IR) radiation in to a measurement chamber containing a respiratory gas, wherein the two different wavelengths include a first IR wavelength and a second IR wavelength. The gas analyzer further includes a first IR detector, a second IR detector, and a beam splitter. The beam splitter is configured to receive the two different wavelengths of radiation emitted by the emitter and to split the two wavelengths of radiation so as to reflect the first IR wavelength to the first IR detector and reflect the second IR wavelength to the second IR detector.

A biological information measurement device which is capable of improving accuracy of detection of optimal exercise intensity, a biological information measurement method, and a biological information measurement program are provided. At the biological information measurement device, heart rate counting means measures an HR value indicating a heart rate on the basis of heart-rate data obtained by capturing heartbeats when a subject to be measured exercises, and analysis means performs power spectrum analysis on a heart rate variability frequency of the heart-rate data to calculate an LF value which is an integral value of low frequency components. Detection means then detects an HR/LF value by dividing the HR value with respect to exercise intensity of the subject to be measured by an LF value. Thus, by the biological information measurement device obtaining the HR/LF value as a new index indicating sympathetic nerve activity, it is possible to obtain biological information important for health management.

A system for measuring a mass of exhaled carbon for weight loss monitoring. The system includes a capture device for capturing exhaled breath and determining a mass of carbon in the exhaled breath, a respiratory inductive plethysmograph (RIP) device incorporated into apparel, and a processor incorporated into a computing device. Mass of exhaled carbon may be determined by the capture device and computing device alone. Alternatively, mass of exhaled carbon may be determined by the RIP device and the computing device alone, after calibration of the RIP device using the capture device.

The present invention is for a method and system for pain classification and monitoring optionally in a subject that is an awake, semi-awake or sedated.

Apparatuses are described to accurately determine a gas concentration of a sample of a patient's breath. The apparatuses may include a sample compartment, a breath speed analyzer, a gas analyzer, and a processor. The sample compartment includes an inlet that receives the breath. The breath speed analyzer determines the speed of a portion of the breath. The gas analyzer determines a gas concentration. The processor includes an algorithm that determines a degree of non-homogeneity of the sample based on the speed, and a corrected gas concentration based on the degree of non-homogeneity. In some variations, the gas correction is determined independently of patient cooperation. Apparatuses may be tuned based on the intended population's expected breathing pattern ranges such that the sample compartment is filled with a homogenous end-tidal gas sample regardless of an individual's breathing pattern. These apparatuses are useful, for example, for end-tidal CO analysis. Methods are also described.
