What is an indication that supplemental oxygen may be needed?

A pulse oximetry reading of less than 92% is a clear indication that supplemental oxygen may be required. The normal range for oxygen saturation typically falls between 95% and 100%. When levels drop below 92%, this can signify that the body is not receiving adequate oxygen, which can lead to hypoxia—a condition where tissues do not get enough oxygen to function properly.

Administering supplemental oxygen in such cases facilitates increased oxygen levels in the bloodstream, helping to alleviate symptoms associated with oxygen deficiency and improving overall oxygenation of vital organs. Monitoring pulse oximetry is a standard practice in evaluating a patient's respiratory status, and a reading below the threshold signals the need for further intervention.
