"Pulse Oximeter - An essential and beneficial medical device The core function of Pulse oximeter is to measure oxygen in blood. This small device can be easily clipped to finger, or another part of the body. Pulse Oximeter is also called a fingertip oxygen meter. The device clips over the tip of your index finger. People with COVID-19 are sometimes instructed by their doctors to monitor their own blood oxygen in this way. As you know Oxygen level is an important sign of how well a body is working, just like a person’s blood pressure or body temperature. People who have a lung or heart condition may use a pulse oximeter at home and can be easily bought without a prescription at some pharmacies and stores. A normal level of oxygen is usually 95% or higher. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. Low blood oxygen cases often have few or no symptoms (""silent hypoxemia""). That is sometimes even true in serious cases of hypoxemia. Some people with low blood oxygen seem well. This is why if you have reason to suspect your oxygen saturation is low, it's helpful to have a pulse oximeter.
