The hemodynamic responses to positive end-expiratory pressure (PEEP) ventilation have been evaluated. A rise in pulmonary capillary wedge pressure which follows the use of PEEP may not reflect changes in left atrial pressure and may be associated with a fall in cardiac output. This increase in pulmonary capillary wedge pressure suggests that there is a high resistance to flow in the pulmonary circulation and that a lower level of PEEP should be used.
对呼气末正压（PEEP）通气的血流动力学反应已得到评估。使用PEEP后肺毛细血管楔压升高可能并不反映左心房压力的变化，且可能与心输出量下降有关。肺毛细血管楔压的这种升高表明肺循环中存在高血流阻力，因此应使用较低水平的PEEP。
