When should oxygen therapy be initiated according to sleep study protocols?

Oxygen therapy should be initiated when the oxygen saturation levels (SpO2) drop below a certain threshold to prevent hypoxemia and its related complications. The threshold for initiating oxygen therapy in sleep study protocols is typically set at less than 88% on room air. This is based on clinical evidence that indicates significant physiological consequences can occur when SpO2 levels fall to this point, potentially leading to inadequate oxygen delivery to tissues and various health issues, especially during sleep when respiratory function may already be compromised.

Maintaining oxygen saturation above this threshold is crucial, particularly for patients undergoing sleep studies, as it reflects their ability to effectively oxygenate themselves during different phases of sleep. By intervening at this level, healthcare providers can help to ensure patient safety and improve overall outcomes.
