How to use pulse oximeter properly to get accurate blood oxygen SpO2 readings – step by step process

Given the rising number of Covid-19 cases in the country, there has been a surging demand for a pulse oximeter. You have probably seen a lot of pulse oximeters available in the market offline or online. But before using it, you need to know actually what it is, and how you will use it.

Let’s get started about it.

What is a pulse oximeter?

Pulse oximetry generally one kind of medical device that is a test used to measure the oxygen level (oxygen saturation) of the blood. Besides that, it also helps to measure the normal heart rate. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs.

The importance of the oximeter tool

Pulse oximeters are medical devices that monitor the oxygen level of a patient’s blood, and it can be beneficial for the healthcare worker if oxygen levels drop below the safe levels. Now it has become an important tool for citizens to understand health status, especially for Covid patients.

According to several reports, a normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels of around 90%. However, if your home SpO2 reading is lower than 90%, it is best to call your health care provider immediately.

At the same time, it is crucial to follow the right procedure to get accurate blood oxygen readings. So now we are going to given you a step-by-step guide to getting accurate blood oxygen readings on your body.
