Figure 1From: Determinants of weaning success in patients with prolonged mechanical ventilationTension-time diaphragmatic index at T0 (black triangles) and T1 (white squares) in the weaned and unweaned groups. Pdisw/Pdimax, ratio of tidal diaphragmatic pressure to maximum transdiaphagmatic pressure. Ti/Ttot, inspiratory time expressed as a fraction of the total respiratory cycle duration.Back to article page
