Question

Quizplus · Accepted Answer

All of the listed factors can potentially cause an inaccurate oxygen saturation reading. Carbon monoxide inhalation can displace oxygen on hemoglobin, leading to a falsely elevated SpO2 reading. Smoking cigarettes can also affect the accuracy of the reading. Finally, dark nail polish or artificial nails can interfere with the reading by preventing light from passing through the finger to the sensor.
