Which term describes normal oxygen saturation when measured by pulse oximetry?

Explanation:
SpO2 describes the oxygen saturation measured by pulse oximetry. It represents the percentage of hemoglobin molecules bound with oxygen in arterial blood and is determined noninvasively by a sensor on a fingertip or earlobe. In healthy individuals, SpO2 normally ranges from about 95% to 100%. This value is what clinicians use to assess how well oxygen is being carried in the blood. The other terms refer to different concepts: dyspnea is shortness of breath, orthostatic relates to posture-related changes in blood pressure, and PVCs are a type of heartbeat irregularity.
