PEEP is intended to do which of the following? A. Improve ventilation/perfusion matching B. Decrease functional residual capacity C. Increased venous return to the heart D. Increased cardiac output A. Improve ventilation/perfusion matching - PEEP increases alveolar volume, thereby improving ventilation/perfusion matching and increasing functional residual capacity. - A detrimental effect of PEEP (especially at high levels) is a decrease in venous return to the heart and a subsequent decre...
