Positive end expiratory pressure (PEEP): 1. decreases dead space ases venous return to the heart 3. decreases intrapulmonary shunting 4. decreases extravascular lung water CORRECT ANSWER Positive end expiratory pressure (PEEP): decreases intrapulmonary shunting The major effect of PEEP is to increase FRC and tidal ventilation above the closing capacity. This results in a decrease in intrapulmonary shunting. Neither PEEP nor CPAP decrease extravascular lung water. By increasing intratho...
