How can you check oxygen level at home?

It is extremely important to get your oxygen levels checked frequently if you are at hoe isolation due to Covid 19. Blood oxygen level refers to the amount of blood that your red blood cells carry around your body. There are several ways to get your oxygen level tested at home. The most common way is to get it checked with a Finger Pulse Oximeter.

The red blood cells carry the oxygen from the lungs, throughout the body through a molecule which is known as hemoglobin. The Pulse Oximeter is a little device where you need to put your finger. The device measures the amount of oxygen that the hemoglobin is carrying around your body to the various organs. This comes as a percentage and is referred to as oxygen saturation. A normal reading is when your percentage is above 95%. Below 92% means your body is not getting enough oxygen. You must consult a doctor in that case.

What is the normal range of oxygen levels?

A Finger Pulse Oximeter is a small device that helps you to check your blood oxygen levels. The reading comes in a percentage of 100 and is referred to as oxygen saturation. A normal saturation level is when your oxygen percentage is above 95%. However, in some people who suffer from lung diseases, etc., the normal blood oxygen level can be 90%.

However, if your oxygen saturation comes less than 92%, consult a doctor.


How much low oxygen level is serious for covid patients?

Blood saturation level refers to the amount of oxygen the red blood cells carry to the various organs of the body from the lungs. The Coronavirus causes inflammation in the lungs of a person that impacts the oxygen supply throughout the organs of the body. A healthy oxygen saturation is when the level is between 94 – 100.

However, it is serious for covid patients if the blood oxygen levels keep dropping below 90. In that case, a person must immediately consult a doctor.


How does a pulse oximeter work?

A Finger Pulse Oximeter is a small device that helps a person to check their blood oxygen levels. That is the amount of oxygen the molecule is carrying from the lungs to the different parts and organs of the body. To get a reading a finger, toe, or earlobe is placed on it. A little light beam passes throughout the toe, earlobe, or the finger placed. The light changes when it comes in contact with oxygenated and deoxygenated blood. The process is quick and painless.


How to check SpO2 levels with smartwatch?

Technological advancements have not even made a smart watch possible to check your oxygen levels. This although was previously available in only high end devices, now can be measured through various smart watches.

Here is how you can measure your blood oxygen level on various smart watches:

Apple Watch Series 6

Open the Health app on your iPhone and set that up. Go to Respiratory, click on Blood Oxygen and then set it up.

Once set, you can go to the apple watch and record your blood oxygen level.

Fitbit Smartwatches:

There are two things that you would need to get a reading of your SpO2 on your Fitbit Smartwatch. They are updated version of Fitbit OS and the other is SpO2 clock face. To get a reading, set the clock face to default. Once done, this will give you a reading of your heart rate, floor count, step count amongst others.

Samsung Wearables:

For getting a reading of your SpO2 level, take your smart phone and go the Samsung Health App. The next step is to pair it with your Galaxy Watch 2.

Realme Watches:

Open your Realme Watch and go to the SpO2 page. To start the measurement, click on the SpO2 option. Wait for a minimum of 30 seconds to view the result.

Are apps a reliable way to measure blood oxygen levels?

With the epidemic hitting the world hard, oxygen levels, especially in covid patients have become a point of concern. Whilst people are finding different ways to measure their oxygen saturation level at home, smartwatches and apps have also found their name in the options for such. However, with this, the question that is apps and smartwatches a reliable source of measuring oxygen saturation level has also emerged.

Well, the answer is no. Research has shown that these smartwatches and apps are not fit to correctly measure the oxygen saturation level. This stands especially true when the oxygen levels are low and need urgent attention.

It is always a better idea to get a Pulse Oximeter from a nearby medical store for keeping an eye on the oxygen level.


What you need to know before buying pulse oximeter?

There are three things that a person must be aware of before purchasing a pulse oximeter. They are:

  • What does a Pulse Oximeter mean?

Pulse Oximeter is a small device that helps in measuring the blood saturation level of a person. Blood saturation level refers to the amount of oxygen carried by the molecule called hemoglobin to the different parts of the body from the lungs. The result comes in a percentage of 100. A normal reading is when the percentage is between 94 – 100. However, in some people who have a certain underlying disease, the reading may show below 94. If the reading is below 90, it is advised to consult a doctor. 

  • How does it work?

A Pulse Oximeter is a small device that helps in measuring the blood saturation level of a person. A finger, toe, or earlobe is put in the device. Small beams of light pass through it the moment the finger etc. is put in the device. The light changes when it comes in contact with oxygenated and deoxygenated blood records the percentage of the oxygenated blood and shows the reading in percentage.

A normal reading is when the percentage is between 94 – 100. It is a point of concern if the reading is below 90. In situations like these, you must immediately inform a doctor.

  • Why do you need a Pulse Oximeter?

The importance of keeping an oximeter home has come to notice after the epidemic hit mankind last year. It was advised by the doctors to keep an oximeter at home to regularly keep an eye on the blood oxygen level of a person. This was more important to the people who were infected by the coronavirus and were in home isolation.

However, infected or not, it is always a good idea to keep an oximeter handy at home. This helps to seek medical attention immediately when the blood oxygen levels drop in any person.
