At a PEEP of 12 cm H₂O,the cardiac output is at its highest level (3.6 L/min),and the mixed venous PO₂ is at its highest level.This correlates with an enhancement in cardiac performance.However,at a PEEP of 15 cm H₂O,both these indices,as well as the blood pressure,are reduced,meaning that the alveoli are overdistended and the point of optimum PEEP is no longer present.
