What is the threshold SpO2 for adding oxygen during a titration study if it drops below this level?

In a titration study for patients with sleep disorders, especially those experiencing conditions like obstructive sleep apnea, a threshold saturation level is established to determine the need for supplemental oxygen. The correct threshold for adding oxygen is set at 88% SpO2.

This level is clinically significant because hypoxemia (low blood oxygen) can cause various short- and long-term health issues. When SpO2 levels drop below 88%, it is generally accepted that the patient's oxygenation is inadequate to maintain proper physiological function, which necessitates the addition of supplemental oxygen to ensure that the tissues receive adequate oxygen and to prevent complications such as pulmonary hypertension, cardiovascular stress, and other organ dysfunction.

Choosing a higher threshold, such as 90% or 92%, may lead to patients remaining hypoxemic for longer periods, potentially increasing the risk of adverse outcomes during sleep. Thus, maintaining SpO2 levels above 88% is crucial in managing patients during titration studies effectively.
