Figure 1From: Determinants of the cuff-leak test: a physiological studyClinical study. Individual cuff-leak volume was measured when the cuff remained deflated both during inspiration and expiration (conventional method, Leakconv) and when the cuff was deflated at the end of 3 s of inspiratory pause (Leakpause). Notice that in all patients Leakconv is higher than Leakpause. Solid line, line of identity; broken line, regression line.Back to article page
