Pulse Oximeters are compact, lightweight, portable devices that are used to monitor a person’s heart rate or pulse rate and the oxygen saturation level in their bloodstream. It is a non-invasive, easy-to-use method for diagnosing symptoms of cardiovascular diseases, pulmonary diseases, asthma, pneumonia, and anemia. A pulse oximeter displays two readings on its digital display. The reading displayed by SaO2 is the unit of measurement that denotes the oxygen saturation level in a person’s bloodstream. In medical terms, this is known as arterial oxygen saturation.
How to use a pulse oximeter
For a healthy adult, the normal oxygen saturation level is between 95% and 100%. But if the oxygen saturation level falls below 88%, it should be a cause of concern. A low oxygen saturation level indicates that either your heart is unable to pump oxygenated blood throughout the body or your lungs are unable to absorb a sufficient amount of oxygen from the environment. A low oxygen saturation level can lead to serious medical complications like hypoxemia. An average adult’s resting pulse rate is 60 to 100 beats per minute (bpm). If your reading is anywhere between 60 to 100 bpm, it means that your heart is in a healthy condition. However, if your resting pulse rate is more than 110 beats bpm, it means that your heart muscles are working extra hard to pump blood around the body. It could be a sign of a potential cardiovascular disease.
To measure your pulse rate and oxygen saturation level, simply clip the pulse oximeter to your index finger and wait for the readings on the digital display to become stable. The pulse oximeter gives you instant readings with utmost accuracy. It is an FDA-approved, painless, and affordable method of monitoring your pulse rate and oxygen saturation level right from the comfort of your home.
