What Is The Important Role Of Oximetry in COVID-19?

With the increasing emphasis on health, the demand for oximeters is gradually increasing, especially after the COVID-19, the demand for oximeters is exponentially more widespread! So what is so unique about this little oximeter and what important role does it play in the fight against the new epidemic in this smokeless battlefield?

What is an oximeter?

　　An oximeter, also known as a pulse oximeter, is a device that monitors the oxygen content of blood in the body in real time without the need for blood sampling, through a detector or sensor. It is a small medical device that measures the body’s oxygen saturation, pulse rate and perfusion index.

　　The oxygen saturation of a normal person is between 94% and 100%, below 90% needs to be taken seriously.
COVID-19 can lead to lung infections which can lower blood oxygen levels. When blood oxygen levels are at a low level, one may feel fatigue and shortness of breath, even without any discomfort, but such a situation can be dangerous. Oximetry is one of the clinical diagnostic methods for neocoronary pneumonia. Changes in blood oxygen levels can be used to determine if you have neocoronary pneumonia, and for some mild cases of neocoronary pneumonia, the lightweight and convenient home oximeter is recommended by doctors.

　　The Protocol for the Treatment of COVID-19 (Trial Version 8) states that oxygen saturation is one of the key criteria for determining severe cases, and that an oxygen saturation of ≤93% on inhalation of air at rest is considered severe.

　　This little oximeter, like the forehead temperature gun used to screen for the epidemic, played a big role in keeping the infected population healthy during the epidemic, as medical institutions in countries with severe epidemics were already operating at full capacity, and people with mild infections could have their health monitored by monitoring their blood oxygen levels.
