Question

You have a​ 38-year-old patient who has fainted. Following your local​ protocol, you use a pulse oximeter to determine the SpO2. You attach the device to the​ patient's finger; it gives you a reading of 91 percent. What does that reading​ indicate?

A. Mild hypoxia
B. Significant hypoxia
C. Normal results
D. Severe hypoxia

Answer 1

A reading of 91 percent on a pulse oximeter indicates mild hypoxia, a lower-than-normal level of oxygen in the blood. Further evaluation is needed to address this condition.

Step-by-step explanation:

A pulse oximeter measures the oxygen saturation level in a patient's blood. A reading of 91 percent indicates mild hypoxia, which means that the patient has a lower-than-normal level of oxygen in their blood. While not severe, this condition still requires attention and further evaluation.
