Ventricular dysfunction occurs in patients receiving positive-pressure ventilation for which of the following reasons?
1) Hypovolemia
2) Excessive tidal volume
3) Receiving more than optimal positive end expiratory pressure (PEEP)
4) Hypervolemia

Question

Quizplus · Accepted Answer

Ventricular dysfunction in patients receiving positive-pressure ventilation can occur due to hypovolemia, excessive tidal volume, and receiving more than the optimal positive end-expiratory pressure (PEEP). Hypovolemia can reduce preload, excessive tidal volumes can increase intrathoracic pressure and impair venous return, and excessive PEEP can also increase intrathoracic pressure, leading to decreased venous return and cardiac output.
