The pulse oximeter may not be reliable in which of the following conditions?
A)Poor circulation
B)Carbon monoxide poisoning
C)Both A and B
D)None of the above

Question

Quizplus · Accepted Answer

Poor circulation can result in inaccurate readings as the pulse oximeter relies on the detection of pulsating blood vessels. Similarly, in cases of carbon monoxide poisoning, the pulse oximeter may not detect the reduced oxygen levels as carbon monoxide binds to hemoglobin and can give a false sense of oxygen saturation. Therefore, both A and B are not reliable conditions for using a pulse oximeter.
