What is the purpose of using a pulse oximeter?

The primary purpose of a pulse oximeter is to monitor a patient's oxygen saturation non-invasively. This device uses light absorption to measure the percentage of hemoglobin in the blood that is saturated with oxygen, providing a quick and reliable indication of a patient’s oxygen levels without requiring invasive procedures like drawing blood. This is particularly important in clinical settings where rapid assessment of a patient’s respiratory status is crucial for timely interventions.

Monitoring oxygen saturation is essential for evaluating patient conditions, especially in those with respiratory illnesses, to ensure they receive adequate oxygenation. The information obtained from a pulse oximeter can guide healthcare providers in making appropriate decisions about oxygen therapy and other interventions.
