High tidal volumes and/or high levels of PEEP can cause which of the following?

Question

Quizplus · Accepted Answer

High tidal volumes and/or high levels of PEEP result in increased resistance to blood flow through the pulmonary circulation; this increases right ventricular afterload.In addition,the right ventricle becomes overdistended,causing a decrease in RV output.Dilation of the RV can also force the interventricular septum to move to the left.Left ventricular output may also be decreased because of the expanding lungs.This plus the decreased venous return lowers cardiac output and decreases the amount of blood perfusing the myocardium.
