How to use a pulse oximeter

It has been reported that the pulse oximeter can be used to measure the severity of the disease if the corona is infected in many people. Instead of simply saying, “Use a pulse oximeter and have a reading, no need to panic,” the basic questions in people’s minds about this machine have been solved.

A small device will instill the belief that you can get rid of this disease without fear of the disease by following the right rules, consulting a doctor from time to time, staying at home without panic, getting proper medical treatment.

A pulse oximeter is a small machine that shows the level of oxygen in our body. How does this machine help you? How do you know the amount of oxygen in your body if you just stick your finger in this machine without inserting any needle? What is the scientific reason for this? Why do we need to have a certain amount of oxygen in our bodies? What is the relationship between the oxygen level in the body and corona? You may have many such questions.

It has been studied how devices are made by combining science and technology while learning biomedical engineering and how the results of these devices while learning physiology are related to what has gone wrong in the body.

What is the relationship between the corona and oxygen deprivation in the body?

The amount of oxygen in the patient’s body when the corona is infected is an indicator of the severity of the disease. When a patient’s immune system is weakened to fight the disease, the virus becomes more prevalent.

People who have underlying causes of high blood pressure, diabetes, heart disease, respiratory disorders, and weakened immunity due to old age are more likely to develop ARDS or Acute Respiratory Distress Syndrome.

Symptoms include difficulty breathing, dry cough, and increased heart rate. The coronavirus affects the patient’s lungs and damages the tiny air sacs in the lungs, called the alveoli.

These alveoli supply oxygen RBCs to the red blood cells through the blood capillaries from the lungs. These cells then carry oxygen to the organs in the body. So hypoxia is a very important indicator. The severity of the corona depends on the level of oxygen in the body and whether the patient needs to be hospitalized immediately.

A pulse oximeter is used to measure the amount of oxygen in your body. Within seconds of placing the finger in the oximeter, you can see the amount of oxygen in the body on its screen. There is no injury or pain to the finger.

Dr. Richard Levitton wrote an article in the New York Times about how the pulse oximeter is useful for measuring the severity of a corona. According to Dr. Richard Levitton, who has worked in emergency medicine for the past 30 years, the pulse oximeter reading in healthy people is 95 to 98 percent.

If the oxygen level in the patient’s body is below 92-94 percent, then the doctor should be consulted to decide whether the patient needs to be admitted to the hospital or not. As long as the oxygen level in the body is above 95, corona can be cured at home with proper medical treatment if there is no difficulty in breathing.

How does Apple Oximeter work without piercing the finger?

Let us now see how this device measures the amount of oxygen in our body by simply placing one finger in the pulse oximeter, without any needle going into the body.

When we place our finger in this oximeter with an electronic processor, two types of light rays, red and near-infrared, fall on our finger through two LEDs and photodiodes. Oxygenated hemoglobin (which carries oxygen) in our body absorbs infrared light at a wavelength of 940 nanometers (wavelength) and deoxygenated hemoglobin absorbs red light at a wavelength of 660 nanometers.

This cycle continues for a few seconds. This is followed by how much light is transmitted. A ratio of oxygenated and deoxygenated hemoglobin is then calculated by applying a correction factor. With the help of a processor (Beer-Lambert), the amount of SpO2 (saturated oxygen) is calculated, which you can see on the display panel of the oximeter.

What is the relationship between the reading on the Apple Oximeter and the corona infection?

So the number you see on the display panel of the oximeter is the amount of saturated oxygen in your body. Suppose a 97% reading on an oximeter’s display panel means that 97% of your body’s hemoglobin carries oxygen.

When the corona is infected and your immune system is unable to cope with it, the disease intensifies and attacks the lungs as mentioned above, which reduces the amount of oxygenated hemoglobin and reduces the readings you see on the SO2.

It is very important to schedule readings at specific times, without deciding on a single reading, to look at the pattern of readings, and if it is consistently low, consult your doctor and be admitted to the hospital.

Which oximeter to buy?

People who are not in the high-risk group do not need a daily oximeter test. It is also advisable to use an oximeter if you feel symptoms of the corona. If not everyone can afford to buy an oximeter, then one can buy one in society.

I am not mentioning any such brand here as it is not the point of this article. Ordinary company name, all the details should be printed well, it is advisable to have a certification. You can also buy a reliable brand by asking your regular pharmacist.

One thing to note here is that the prices of pulse oximeters skyrocketed as word spread among the people that the oximeter could help them before the corona grew. The equipment which used to cost Rs 1,200 is now available for Rs 3,000 / -. Even in the dire situation, we are in today, I was convinced that there should not be a black market for these devices.

Use mobile apps to measure oxygen?

Another important thing is that there are apps for measuring oxygen on mobiles as well, but according to many researchers and doctors, the reliability of measuring these apps accurately is low.

Also, some fraudulent links to the Oximeter are currently being spread. You have downloaded these apps and put your finger on the sensor to check the oxygen. Your fingerprint details and personal data and bank account details etc. are likely to be stolen. This is a type of cybercrime so avoid downloading any app of this method without checking the credibility.

When you take readings, it is also important to take readings from other people in the house and calibrate the equipment accordingly. It is important to make sure that the device we are using shows correct and accurate readings!

6MWT-Six-minute walk test

The 6MWT, or Six-Minute Walk Test, is recommended for people in the high-risk group or those who have been diagnosed with corona and have an oxygen level below 94 percent. Sometimes people use an oximeter for no reason, even when there are no symptoms of the corona, and are suddenly frightened if the readings suddenly decrease.

Even then, the test can be done at home. The test is simple. Take readings on the oximeter once before running. Then walk at a normal pace for six minutes. This should be stopped immediately if you have heart disease and have difficulty walking or breathing. After walking for six minutes, try reading again.

If you feel very tired and the reading goes down by 3%, then you should contact your doctor. The medical journal “The Lancet” found that coronary arrhythmias in patients with coronary artery disease increased their oxygen levels when they slept on prone positions. Therefore, if you do not panic under any circumstances, talk to your doctor without panic, inform the administration and get proper medical treatment, be vigilant without washing your hands and feet and follow all the rules of social distance, you can be protected from the corona.
