What is the role of a pulse oximeter in patient care?

A pulse oximeter is primarily utilized to monitor oxygen saturation levels in a patient's blood, which is crucial during the administration of anesthesia and sedation. By providing continuous feedback on the percentage of hemoglobin that is saturated with oxygen, it allows healthcare providers to assess a patient's respiratory status in real-time. This is particularly important during procedures where the patient's airway might be compromised or where they are receiving medications that can depress respiratory function.

Monitoring vital signs, including oxygen saturation, helps in making prompt decisions regarding the patient's care, such as the need for supplemental oxygen or changes in anesthesia depth. This role is essential in maintaining the patient's safety and ensuring that any potential complications related to oxygenation are addressed quickly.
