Blood Oxygen Monitors (Pulse Oximeters)

Zacurate Pro Series 500DL Blood Oxygen Saturation Monitor

Blood oxygen monitors, often referred to as pulse oximeters, are medical devices designed to measure the saturation of oxygen in a person’s blood. This non-invasive tool works by passing light through a translucent part of the patient’s body, usually the fingertip or earlobe, to measure the amount of oxygen in the blood. The device then provides a numerical reading which represents the percentage of hemoglobin in the arterial blood that is oxygen-saturated.

Understanding the level of oxygen saturation in the blood is crucial because it provides insights into how effectively a person’s lungs are transferring oxygen into the blood and how efficiently the circulatory system is delivering this oxygenated blood to the rest of the body. In healthy individuals, blood oxygen levels typically fall between 95% to 100%, though this range can vary slightly depending on the source. Levels below 90% are generally considered low and might indicate a medical emergency.
