Which indicator of hypoxemia in an anesthetized patient is best in terms of continuous monitoring early warning:

Question

Quizplus · Accepted Answer

Pulse oximeter reading less than 90% is the best indicator of hypoxemia for continuous monitoring and early warning in an anesthetized patient. This is because it provides a real-time measure of blood oxygen saturation levels, which can change quickly and unpredictably during anesthesia. Capnometric reading of 40 mm Hg, ECG showing arrhythmias typical of myocardial anoxia, and Pao2 less than 60 mm Hg are also indicators of hypoxemia but may not be as sensitive or reliable as pulse oximetry for continuous monitoring.
