Figure 4From: Effects of positive end-expiratory pressure on respiratory function and hemodynamics in patients with acute respiratory failure with and without intra-abdominal hypertension: a pilot studyPressure-volume (P-V) relationship in patients with normal intra-abdominal pressure (IAP; left panel) and intra-abdominal hypertension (IAH; right panel) as a function of PEEP. The progressive shift to the left (i.e. at the same pressure the volume is higher at higher positive end-expiratory pressure (PEEP)) with increasing PEEP suggest recruitment. Data are presented as mean ± standard deviation.Back to article page
