Abstract (en)

[origin: WO2006099863A1] The residual capacity of breathable air remaining at any point for an oxygen-generating breathing apparatus operated in circuit is determined by measurement of the number of breathing cycles and the pressure and temperature of the inspired air in sequential periods by means of a pressure and temperature sensor. The current breathed air usage is calculated for each time period and subtracted from the total air capacity. The residual capacity of breathable air at a given reading point is displayed on a display.
