1) Volume overload
2) Tension pneumothorax
3) Spontaneous inspiration
4) Increased intrathoracic pressure

Question

Quizplus · Accepted Answer

Volume overload increases blood volume, raising CVP. Tension pneumothorax compresses the heart and great vessels, increasing CVP. Increased intrathoracic pressure, such as from mechanical ventilation, also raises CVP. Spontaneous inspiration decreases intrathoracic pressure, lowering CVP.
