Why Must Every Home Have a Pulse Oximeter?
 

Introduction:

This is a high-end electronic device that is operated by clipping on the finger of the person who needs to measure the index. It measures the heart rate and oxygen saturation of red blood cells. A clip-like device called a probe is placed on a certain part of the body, which uses light to measure the oxygen level in the blood. This information can help healthcare providers decide whether a patient needs additional oxygen.

Pulse oximeters are often used by hospital professionals, and you can use them at home to help doctors monitor your health remotely and give you relevant advice. The most important thing is that blood oxygen saturation is an important indicator for the treatment of COVID-19.

Oxygen saturation is the ratio of oxygen-saturated hemoglobin to total hemoglobin in the blood. Normal arterial oxygen saturation in humans is 95% – 100%, if this level is below 90%, it is considered a low level, called hypoxemia. Arterial oxygen levels below 80% may impair organ function, such as The brain and heart should be dealt with immediately. Sustained low oxygen levels can lead to respiratory or cardiac arrest. Oxygen therapy can be used to help increase blood oxygen levels. Oxygenation occurs when oxygen molecules (O2) enter human tissues. For example, blood is oxygenated in the lungs, and oxygen molecules enter the blood from the air. Oxygenation usually refers to medical oxygen saturation.
