Figure 5From: Short-term effects of positive end-expiratory pressure on breathing pattern: an interventional study in adult intensive care patientsEffects on breathing pattern brought on by steps in PEEP of different duration. Effects are shown on VE, which behaved similarly whether the PEEP steps were applied for 10, 30, or 60 s. *P < 0.025, versus zero PEEP. PEEP, positive end-expiratory pressure; VE, minute ventilation.Back to article page
