What does the term "spO2" stand for in sleep studies?

The term "spO2" stands for Peripheral capillary oxygen saturation, which refers to the percentage of oxygen-saturated hemoglobin in the blood relative to the total hemoglobin. This measurement is significant in sleep studies as it helps assess the adequacy of oxygenation during sleep, particularly in patients with sleep apnea or other respiratory issues. Monitoring spO2 levels is crucial because fluctuations in oxygen saturation can lead to hypoxia, which may affect overall health and sleep quality. By accurately measuring spO2, healthcare providers can evaluate a patient's respiratory function during sleep and make informed decisions about their treatment options.
