Understanding the Two Readings on a Blood Oxygen Monitor
A blood oxygen monitor, also known as a pulse oximeter, is a medical device used to measure the oxygen saturation level in the blood and the heart rate. These devices provide two important readings: oxygen saturation (SpO2) and pulse rate.
The oxygen saturation reading, Expressed as a percentage, indicates the amount of oxygen carried by red blood cells. A normal SpO2 level is typically between 95% and 100%, indicating that the blood is well oxygenated. A lower level may indicate hypoxemia, which can be caused by various medical conditions.
The pulse rate reading, measured in beats per minute, reflects the heart rate. A normal resting heart rate for adults ranges from 60 to 100 beats per minute. A higher or lower pulse rate may indicate an underlying health issue.
It's important to note that the readings provided by a blood oxygen monitor should be used as a reference and not as a definitive diagnosis. If you have concerns about your oxygen levels or heart rate, it is best to consult a medical professional.
