Figures
- Fig. 1.
Experimental setup for all tested conditions.
- Fig. 2.
Typical esophageal pressure and flow tracings at rest (A and C) and during effort (B and D), without and with a gas mask. (subject 3).
- Fig. 3.
Variations in the indexes of respiratory effort with the gas mask, at rest and during an effort. The p-values refer to the comparisons of the different indexes of effort, without and with masks. N = 14. WOB = work of breathing; PTP = pressure time product; Pes = esophageal pressure.
- Fig. 4.
Variations (%) in the respiratory resistance and auto-PEEP with the gas mask, in comparison with and without, at rest, and during an effort. N = 14; CL = dynamic lung compliance; Res = respiratory resistance.
- Fig. 5.
Typical SpO2 signal tracings in the tested conditions (subject 15). A and B: During rest. C and D: During effort.
