The U.S Food and Drug Administration (FDA) is informing patients and health care providers that although pulse oximetry is useful for estimating blood oxygen levels, pulse oximeters have limitations and a risk of inaccuracy under certain circumstances that should be considered. Patients who monitor their condition at home should pay attention to all signs and symptoms of their condition and communicate any concerned to their health care provider. It is also recommended that users establish a baseline value when health and at rest.
