A normal level of oxygen is usually 95% or higher. If your home SpO2 reading is lower than 95%, call your health care provider. Low oxygen levels can be an early warning sign that medical care is needed. A pulse oximeter may indicate issues with blood oxygen levels which could be related to coronavirus.
With Its compact model, Pulse Oximeter can provide the same valuable data as compared to the ones which are placed on you when you are in the hospital. To use a finger pulse oximeter, you place one end of the device on your fingertip and the reading comes up on the screen in a few seconds.
