Abstract
The present invention relates to a respiratory gas consumption monitoring method and monitoring device that is portable and has high measurement accuracy, for enabling the analysis and prediction of the respiratory behavior of subjects employing a variety of different types of breathing apparatuses in water, etc. Respiratory gas consumption monitoring device (20), for monitoring the respiratory gas consumption of the user of a breathing apparatus (1) in which a respiratory gas (G) inside a high pressure gas container (2) is reduced in pressure at pressure regulator (4) and supplied to a breathing mask (10), is provided with: PA1 a primary pressure sensor (21) for detecting the pressure prior to pressure reduction at pressure regulator (4); PA1 a temperature sensor (22) for correction; PA1 an environmental pressure sensor (23) for detecting the environmental pressure; PA1 an amplifier (24) for amplifying the signals from the aforementioned sensors; PA1 an A/D converter (25) for performing analog/digital conversion of the amplified signal; PA1 a data logger (26) for recording and storing the analog/digital converted signals; and PA1 a display (27) for display. In addition, as needed,…
