Which of the following may indicate a decrease in systemic vascular blood flow during high-frequency ventilation?
I.high central venous pressure (CVP)II.low CVP
III.decreased mean arterial pressure (MAP)IV.increased MAP

Question

Quizplus · Accepted Answer

A decrease in systemic vascular blood flow during high-frequency ventilation can be indicated by low central venous pressure (CVP) and decreased mean arterial pressure (MAP). Therefore, options I and III are correct. However, an increased MAP is not a sign of decreased systemic vascular blood flow, so option IV is incorrect. Option II could be a sign of decreased systemic vascular blood flow, but high CVP is not a common finding in such cases. Therefore, option B is the best choice.
