Question

Pulse oximetry values should be above _____% to reduce risk of hypoxemia

Answer 1

Pulse oximetry values should be above 95% to reduce the risk of hypoxemia and ensure adequate oxygen levels in the blood, with normal readings ranging from 95-100 percent.

Step-by-step explanation:

Pulse oximetry values should be above 95% to reduce the risk of hypoxemia—which encompasses low levels of oxygen in the blood. A device called a pulse oximeter measures the percent saturation of hemoglobin in the blood. Normal readings obtained from the device range from 95-100 percent. When oxygen levels drop below this range, it indicates hypoxemia or low blood oxygen. It is critical especially for neurons, as they can experience damage or death if blood and oxygen supplies are not quickly restored.
