Measurement of oxygen saturation by pulse oximetry may produce an erroneous reading in the presence of:
A) Increased concentration of Hb
B) Shivering
C) Metabolic acidosis
D) Respiratory alkalosis

Question

Quizplus · Accepted Answer

Shivering can cause mild to moderate changes in oxygen saturation readings, as it can lead to variations in blood flow and tissue perfusion. Increased concentration of Hb, metabolic acidosis, and respiratory alkalosis do not typically affect the accuracy of pulse oximetry readings.
