The physician has decided to implement permissive hypercapnia with an ARDS patient receiving mechanical ventilation. What should be the pH goal with the patient?

Question

Quizplus · Accepted Answer

With permissive hypercapnia, the focus is on allowing the partial pressure of carbon dioxide (PaCO2) to rise above normal levels while still maintaining adequate oxygenation. The goal pH range still remains within normal physiology, thus the pH goal should be maintained at a range of 7.35-7.45 to minimize the risk of acidosis or alkalosis. A pH goal of <7.2 would be too low and may lead to adverse effects such as impaired tissue perfusion and acidemia. A pH goal of >7.45 would be too high and may lead to adverse effects such as alkalosis and impaired oxygen delivery to the tissues.
