Table 3 Pairwise comparisons of main outcomes across positive end-expiratory pressure levels

From: The effect of positive end-expiratory pressure on cardiac output and oxygen delivery during cardiopulmonary resuscitation

PEEP level pairs Cardiac output (l/min) PaO2 (mmHg) Oxygen delivery (ml/min)
