What is the function of a pulse oximeter during a sleep study?

• A. Measure heart rate
• B. Monitor oxygen saturation
• C. Record sleep stages
• D. Measure CO2 levels

Answer: (B)

The function of a pulse oximeter during a sleep study is to monitor oxygen saturation levels in the blood. This is crucial because it helps determine how well oxygen is being delivered to the body's tissues while a patient sleeps. During a sleep study, clinicians are particularly concerned about conditions like sleep apnea, where intermittent pauses in breathing can lead to drops in oxygen levels. By observing the oxygen saturation readings, healthcare professionals can assess the severity of apnea events and their impact on the patient's overall health and sleep quality. Monitoring oxygen saturation provides valuable information that helps diagnose respiratory issues and tailor appropriate interventions during the study.
