Why Must Every Home Have a Pulse Oximeter?

Nov 8, 2022

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.

Why might you need a pulse oximeter?

A pulse oximeter is required in many situations, and its benefits are most pronounced in patients with symptoms of COVID-19 such as cough, fever, and shortness of breath. If you have similar symptoms, this is a reasonable time to check your blood oxygen saturation. Oxygen levels were also one of the determinants of getting them into hospitals because at the height of the outbreak, hospitals were running out of beds and emergency rooms were overcrowded. People are diagnosed with COVID and sent home. The purpose of a pulse oximeter is nothing but an early warning of a drop in oxygen saturation.

How to use a Pulse Oximeter at home?

First turn on your newly purchased pulse oximeter, check for power and select any of your fingers to clip, with the nail facing up, and you will see the results after a few seconds.

A pulse oximeter will give two results: blood oxygen level and pulse rate, combined with the normal values I told you above to see if you are healthy. Many factors affect the value. affect the value. For example, if you apply nail polish or artificial nails, the device may not display the result. At this time, you should remove the nail polish or try a different finger.

Keep the pulse oximeter on your finger for at least a minute, longer if the readings keep changing. The highest result was recorded when the reading did not change within 5 seconds. Take care to identify which reading is your heart rate and which is your oxygen level.

Can an Oximeter Help Detect COVID-19 at Home?

Many people are wondering whether a pulse oximeter can help you test for COVID-19 at home. The novel coronavirus that causes COVID-19 enters the body through breathing, causing direct damage to a person’s lungs through fever and pneumonia, both of which can negatively affect the efficiency of oxygen entering the bloodstream. This hypoxia can occur in multiple stages of COVID-19, not just in critically ill patients on ventilators.

Evidence that declining blood oxygen levels are a key indicator of worsening health in COVID-19 patients shows how important it is to have a pulse oximeter at home.

Conclusion

I believe everyone has a general understanding of pulse oximeters. Every family must have a pulse oximeter. In addition, you can also learn about other signs or symptoms of low oxygen levels:
Such as shortness of breath, difficulty breathing or coughing, chest pain or tightness, and bluishness of your face, lips, or nails. If you have any concerns, please drop me a line or contact your healthcare team directly.
