Quizplus · Accepted Answer

The pulse oximeter alarm sounds when the SpO2 level drops below a set threshold. SpO2 is the measure of oxygen saturation in the blood. If it is low, it indicates that the patient is not getting enough oxygen, which can be a critical situation requiring immediate medical attention. The other options (A, B, and D) are not directly related to the pulse oximeter alarm.
