10 best pulse oximeter | how it works SaO2 meter | Price & review

What is a pulse oximeter?
A pulse oximeter is a small, lightweight portable human body that measures the level of oxygen in the human body and determines the heartbeat rate. It is basically a non-invasive method for monitoring oxygen saturation (SaO2).

Why use?

This is why we use this Oxygen Saturation (SaO2) measuring device because the asymptomatic Covid-19 patients are those who are infected with the coronavirus but have no symptoms. As a result, before the patient understands anything, his blood oxygen level decreases drastically. This medical device needs to be used to control oxygen levels.

We are all very worried during this time. If I have a cold cough or shortness of breath, I think I have corona. But shortness of breath can be due to various reasons. If you have a pulse oximeter at that moment, you can test it. If it is normal, you can say with a sigh that nothing has happened to me, but if the level of oxygen decreases, then the messenger will be the doctor’s removal, otherwise, the danger may go away.

It is normal for the patient to have difficulty breathing when the oxygen level decreases, but in the case of a patient infected with coronavirus, different oxygen depletion can be adjusted immediately.

People suffering from complex respiratory diseases including asthma, bronchitis should have this device nearby. Any potential coronavirus patient who has been around can also use this device. People with long-term lung or heart disease, including diabetes and high blood pressure, are more likely to develop Covid-19. So these people should keep the oxygen level in the blood right. And those who are providing medical services should use the device regularly.

We have been experimenting with pulse oximeters for some time and have talked to several doctors to find out which brands of oximeters work best and are comparatively accurate.

Today we will discuss the top 10 pulse oximeters.

What is the normal reading of the pulse oximeter?

In a healthy human body, 69 percent of the blood carries oxygen. And through this process of oxygen transport, the health or illness of the body is determined.

According to this oximeter, the normal level of oxygen in the blood is 95 to 100%. If it is less than 95 percent, it is called hypoxia in medical health, which means there is a deficiency of oxygen. And if the level drops below 92%, it is considered abnormal. If it is below 92, it is necessary to have a doctor’s removal. And if the heartbeat rate is less than 75 to 80, then reading is considered as unnatural.

Again, many diseases can be different, such as orgasm or feeling happy. Also, for those who have asthma, it is normal for them to give ‘readings’ in normal conditions. Also, with the advice of a doctor, you will find out how much you are normal.

Terms of use

Although the device is usually placed on the fingers, it can also be placed on the toes or earlobes. The device determines the level of oxygen in the blood with the help of light. It is basically measured by all the fingers of both hands. For those who are accustomed to working with the right hand, the middle and thumb of the right hand and for those who are accustomed to working more with the left hand, the middle and thumb of the left hand give good readings.

How does a pulse oximeter work

After inserting the finger into the oximeter, one part of the device emits light through the blood and the other party receives it. The amount of oxygen in the blood is determined by measuring how much of it has been absorbed into the blood during the movement of light through the blood.

Can an oximeter ever give the wrong result?

Many expert doctors may say that the oximeter does not work properly if the hand is colder than the body temperature. In that case, the pulse oximeter may give the wrong result.

We all know that through the lungs we receive oxygen and through the blood, it flows throughout the body. The transport of oxygen in the human body is called hemoglobin transport. The percentage of oxygen hemoglobin in the blood is called oxygen saturation. This is called SPO2 for short.
