Question

Select the TRUE statement regarding pulse oximetry.

A) SpO₂ is a direct measurement of the oxygen content in arterial blood.
B) The pulse oximeter continuously reports peripheral capillary blood oxygen saturation, heart rate, and heart rhythm regularity.
C) Environmental light in the operating room never interferes with the pulse oximeter because the pulse oximeter only detects light in the infrared region.
D) All of the above statements are true.

Answer 1

The pulse oximeter continuously reports peripheral capillary blood oxygen saturation, heart rate, and heart rhythm regularity.

Step-by-step explanation:

The correct statement regarding pulse oximetry is B) The pulse oximeter continuously reports peripheral capillary blood oxygen saturation, heart rate, and heart rhythm regularity.

Pulse oximetry is a non-invasive method of monitoring the oxygen saturation level in the blood. It measures the percentage of hemoglobin in the blood that is saturated with oxygen. The pulse oximeter uses two different wavelengths of light to measure the absorption of oxygen in the blood and calculates the oxygen saturation level based on this measurement.
