Fig. 5From: Bias flow rate and ventilation efficiency during adult high-frequency oscillatory ventilation: a lung model studyRelationship between actual stroke volume (aSV) and ventilation efficiency (\( \dot{\mathrm{V}} \)A/a\( \dot{\mathrm{V}} \)E). Legend: Markers indicate individual data of aSV and \( \dot{\mathrm{V}} \)A/a\( \dot{\mathrm{V}} \)E. Dotted lines are the first-order approximations. The coefficient of correlations (R) and P values are as follows: BF = 10: R = 0.824, P < 0.001; BF = 20: R = 0.989, P < 0.001; BF = 30: R = 0.990, P < 0.001; and BF = 40: R = 0.996, P < 0.001Back to article page
