PR is the heart rate, which is the number of times the heart beats per minute. And SpO2 is blood oxygen saturation, a measure of the amount of oxygen delivered to the tissues from the blood. Both are important indicators of the body's health and are often used by healthcare professionals.
When do I need to test my PR and SpO2?
People need to monitor their PR and SpO2 when they are exercising or when they are not feeling well.
If the values of these indicators are abnormal, it means that there may be a problem with the body, and that you need to go to the hospital in time to have it checked. In addition, some people have chronic conditions such as heart disease and respiratory disease that require long-term monitoring of PR and SpO2 levels.
There are a number of home medical devices on the market today that can be used to test PR and SpO2 levels. These devices usually contain a small clip that can be clipped to a finger or to an earlobe. The device will test SpO2 by emitting an infrared sensor and PR by measuring the heartbeat.The testing process is simple and does not require a medical professional. However, for people at high risk, it is still recommended to go to the hospital for a checkup.
