What is the primary role of a pulse oximeter during sedation?

The primary role of a pulse oximeter during sedation is to monitor the oxygen saturation levels in the patient's blood. This non-invasive device provides real-time information about how effectively oxygen is being transported in the bloodstream, which is crucial during sedation procedures. Maintaining proper oxygen saturation is vital for patient safety, as sedation can depress respiratory function, leading to potential hypoxia.

By tracking oxygen levels, healthcare providers can quickly identify if a patient is not getting enough oxygen, allowing for timely intervention if necessary. This functionality is critical, especially since patients may have altered physiological responses during sedation. Monitoring oxygen saturation helps ensure that patients remain safely within acceptable ranges throughout the sedation process, thereby reducing risks associated with anesthesia.
