Final answer:
Mr. omendas oxygen saturation of 95%, as gauged by a pulse oximeter, falls within the normal range of 95-100%. Lower readings might indicate hypoxemia or hypoxia, both of which represent low oxygen levels.
Step-by-step explanation:
Oxygen saturation is usually recorded using a device called a pulse oximeter, which is normally placed on a thin part of the patient's body, such as the tip of the finger. This device works by sending two distinct wavelengths of light through the finger and measures the exiting light with a photodetector. Hemoglobin absorbs light differently based on its oxygen saturation. The machine computes the differential absorption of the light and presents the data as percent saturation. The acceptable range of pulse oximeter readings is between 95-100 percent, so Mr. Omendas's reading of 95% suggests that his blood oxygen saturation is normal. If the percent saturation dips below 95%, it may indicate hypoxemia, or low blood oxygen levels. More generally, low oxygen levels are referred to as hypoxia.
