Medical experts claim that COVID-19's troublesome symptom can be detected by an oximeter. Scientists and other researchers claim that this tool can identify if people are infected with the novel coronavirus.
According to News Week's latest report, some patients are using oximeters during the ongoing global pandemic to check and monitor the level of oxygen in their bloodstreams.
"A pulse oximeter measures the level of oxygen saturation in your red blood cells," said the American Lung Association via News Week.
The health agency added that the oximeter has gained the attention of many people and medical experts during the COVID-19 pandemic since it can identify if a person is suffering from hypoxia, which is one of the most troublesome COVID-19 symptoms.
Hypoxia is a health issue that makes blood oxygen saturation lower than the normal rate.
How does the oximeter work?
BBC News explained that an oximeter is slipped over the patient's middle finger. Once it is in place, it will shine a light into the body. The medical tool can measure how much of the light is absorbed in order to calculate oxygen levels in the bloodstream.

Usually, people are testing their blood oxygen levels three times a day. If a patient notices that his blood oxygen level is below 92%, that means he needs to call 999 or A&E. On the other hand, if the patient's oxygen levels drop to 93% or 94%, then he should speak to his GP or contact the emergency number 111.
Current studies also revealed that even small drops below 95% could lead to possible death case.
"The point of this whole strategy is to try to get in early to prevent people getting that sick, by admitting patients at a more salvageable point in their illness," said Dr. Matt Inada-Kim, a consultant in acute medicine at Hampshire Hospitals, via BBC News.

Before you decide to buy an oximeter, you should properly read its manual or do some research first. It is also highly advisable to ask you, doctor, before you decide to order one. FDA advised the public that an inaccurate reading could lead to serious health risks.
