Fig. 2From: Pendelluft in hypoxemic patients resuming spontaneous breathing: proportional modes versus pressure support ventilationRespiratory drive and inspiratory effort variables during partial support ventilation modes. Compared with PSV, patients during proportional modes (NAVA and PAV +) presented a higher pressure–time product [PTP] per minute (panel A), a higher delta Pes at the first 100 ms from the onset of inspiration [ΔPes 100 ms] (panel B), and a higher PTP during the first 300 ms [PTP300ms] (panel C) (*p < 0,05; †p < 0,001; and, ‡p < 0,0001 all compared with PSV)Back to article page
