Relationship between setting stroke volume (sSV) and actual stroke volume (aSV) or airway pressure amplitude (Amp) in the R100. Markers indicate individual data. Y-axis in b is the airway pressure amplitude (Amp) displayed on the panel of the oscillator. Dotted lines in the a are first-order approximations. The coefficient of correlations (R) and P values are as follows: 6 Hz: R = 0.993, P < 0.001 and 8 Hz: R = 0.996, P < 0.001. Dotted curves in Fig. 2b are exponential approximations. The exponentials (coefficient of correlations (R), P values) are as follows: 6 Hz, 1.398 (R = 0.996, P < 0.001) and 8 Hz, 1.675 (R = 0.995, P < 0.001)
