Adverse cardiovascular effects of PEEP can include progressive reductions in cardiac output as mean airway pressure and, secondarily, mean intrathoracic pressure rise. The principal mechanism appears to be a progressive decrease in venous return to the heart.Click to see full answer. Herein, what is an adverse effect of PEEP?1. Auto-PEEP, or intrinsic PEEP, is due to inade- quate time for lung emptying in the setting of increased airway resistance and expiratory flow limitation. b. Adverse effects include increased work of breathing, risk of barotrauma or volu- trauma, and hemodynamic compromise.One may also ask, how does peep affect hemodynamics? The beneficial effects of PEEP on lung function may be counteracted by its hemodynamic sequelae induced by a reduction of venous return due to the elevated intrathoracic pressure, and by an increased right ventricular afterload secondary to the rise of pulmonary vascular resistance. Subsequently, question is, what is the purpose of peep? The purpose of PEEP is to increase the volume of gas remaining in the lungs at the end of expiration in order to decrease the shunting of blood through the lungs and improve gas exchange. PEEP is done in ARDS (acute respiratory failure syndrome) to allow reduction in the level of oxygen being given.How does peep affect cardiac output?Second, PEEP increases intrathoracic pressure, particularly when used in focal processes. This decreases venous return and cardiac output with subsequent adverse effects on systemic blood pressure and tissue oxygen delivery.
