Pulse Oximeter: Essential Things to Know

Many factors, such as whether you need to come to the hospital, give oxygen, or need more medication, are determined by the level of oxygen in your body, as well as physical difficulties. This is where every patient needs to know the use of the pulse oximeter.

The pulse oximeter is a new term that we have heard with the corona expansion. It is a simple device for measuring blood oxygen levels or oxygen saturation rate without taking blood. The machine that once operated with the sound of a kiki with a long belly and a large screen on the finger of a patient who was accidentally admitted to the ICU and casualty of a hospital has now reached all of us in the form of a baby. However, there are many pitfalls due to not knowing how to use this machine, misreading the readings, and the machines being compliant. In this case, it is essential to know its use and function.

It is not possible to admit everyone with covid symptoms to the hospital in the present circumstances. Therefore, patients who are largely ill and have adequate oxygen levels in their blood are advised to take medication at home, rest, and come to the hospital if necessary. Many factors, such as whether you need to come to the hospital, give oxygen, or need more medication, are determined by the level of oxygen in your body, as well as physical difficulties. This is where every patient needs to know the use of the pulse oximeter.

It has a clip-on top with an LCD. This machine is set on the fingers to check the oxygen level. If you are right-handed, it fits on the index or middle finger of the right hand. On the left fingers of the left hand. Sanitize well, wipe dry and put your finger inside it. If you have nail polish, henna, and election ink on your finger, it will show a false report, so you should use it on fingers that have none.

Put your finger on it and press the on button. Then a small display will appear and the sound will start to be heard. If held for a while – less than 1 – 2 minutes – it will have two types of value. The part written as SPO2 shows the oxygen saturation rate in the body. There will also be a percentage where that amount is recorded. Thus, by looking at the value written as a percentage, the average person can confirm that it is an oxygen level. (Many people see the following pulse rate of 70.75 and are afraid that the doctor will tell them that the oxygen rate is low. The shortcut I can tell them to avoid this is that the value below this percentage mark is the oxygen level).

Normal blood oxygen levels are above 94. It is most common in people with or without other diseases. The doctor should be consulted when it is severely reduced and shows below 94. By looking at this very simple reading we can know the disease information at home

Below this is the pulse rate. It varies from 60 to 110 depending on age and physical condition. Often a fault in the pulse oximeter leads to a misdiagnosis. It can cause illness to go unnoticed and sick people to panic. In such a case it would be good to see if the same value is shown using one’s different finger to know if this machine is working. Similarly, if you look at others in a healthy home and make sure it is normal, you can tell if it is working or not.

According to the ‘demand and supply theory, the pulse oximeter has now become one of the most sought-after items. The pulse oximeter which was available in the market for Rs. 700-800 is not available today even if you pay Rs. 1500. Counterfeit products are also coming down a lot. To avoid this, the local ward member / RRD member should buy a few pulse oximeters. Give to the next person after each use. If not, it could lead to artificial scarcity and counterfeiting

We also saw a disease called happy hypoxia during this corona period. There are no symptoms of the corona. However, when looking at the pulse oximeter, the oxygen saturation level is very low. In such a case, all healthcare / patient contacts should check their oxygen saturation level even if they are asymptomatic.

No need to panic immediately if the value goes down in any situation. All you need to do is give them the support they need to keep going.
