WebJun 17, 2015 · PEEP is the final phase variable in a breath cycle and describes the “baseline” pressure which remains behind after inspiratory pressure is released, as the patient exhales. WebPhysiologic Effects of PEEP The ARDS lungs ( 14) are characterized by heterogenous collapse of gravity-dependent and highly inflamed zones, which induces a reduction of the respiratory system compliance (C RS ). Alveolar collapse represents one of the main triggers for the detrimental effects of ventilation. bristol motor speedway hats
