What does a pulse oximetry reading below 92% indicate?

A pulse oximetry reading below 92% indicates that there is a potential for hypoxemia, which is an inadequate level of oxygen in the blood. Normal pulse oximeter readings typically range from 95% to 100%, so a reading below 92% signals that the oxygen saturation is compromised. This could require medical attention or an intervention, such as supplemental oxygen or further evaluation of the patient's respiratory status. Detecting low oxygen saturation early is critical in preventing complications related to hypoxemia, which can adversely affect organ function and overall health. Monitoring pulse oximetry is an essential tool in assessing respiratory effectiveness and guiding treatment decisions.
