What is the purpose of a "SpO2" monitor?

The purpose of a "SpO2" monitor is to measure the oxygen saturation level in the blood. This non-invasive device uses infrared light to determine the percentage of hemoglobin that is saturated with oxygen in the bloodstream. Normal oxygen saturation levels typically range from 95% to 100%, and monitoring SpO2 is crucial in various medical settings, particularly during anesthesia and critical care, as it helps determine whether a patient is receiving adequate oxygenation.

Maintaining optimal oxygen levels is vital for ensuring that organs and tissues throughout the body are receiving sufficient oxygen supply, which affects overall health and recovery during medical procedures. Regular monitoring can provide early indications of potential hypoxemia (low blood oxygen levels), prompting timely interventions to ensure patient safety.
