From: Repurposing CPAP machines as stripped-down ventilators
Plots of the airway pressure, flow, ventilation volume as a function of time. (a) Ventilation data plots acquired for the I:E ratios 1:1 and 1:2 while the respiratory rate and the PIP value are set to 20 bpm and 20 cmH2O, respectively. (b) Ventilation data plots acquired for the respiratory rates 16 bpm, 20 bpm and 26 bpm while the I:E ratio is 1:2 and the PIP value is 20 cmH2O. All measurements are conducted on an artificial lung and the pressure is generated with the CPAP machine u1 (see Table 3).
