What makes COVID-19 difficult to address is that it is not just a new virus but it has some mysteries that science is still continually discovering. One of the mind-boggling issues of COVID-19 is why the oxygen levels drop endangering the patient without knowing.
As a result, many COVID patients come to the hospital with worsening conditions than they realized. And in the same cases, too late for intervention.
Known to science as Hypoxia, it takes place when the oxygen levels in the blood go down below the normal level. When oxygen levels drop below normal, the body function will be affected.
A solution that has the potential to save one’s life has been developed, a pulse oximeter that lets Covid patients monitor the oxygen levels while at home. They are now being used for high-risk patients in the UK. And the doctor recommends everyone to buy one.
To know that one has a normal oxygen level in the blood, one has to have a 95% to 100% gauge. Many of the patients brought to the hospital have 70% or even lower, the milder have more or less 85% oxygen level, said Dr. Matt Inada-Kim. Dr. Matt is an acute medicine specialist from the Hampshire Hospitals.
In using the pulse oximeter, just slip it over the middle finger and the display will show the rate of oxygen levels. When the device is placed into the middle finger the light will shine into the body. To determine the oxygen levels in the blood the device will measure how much of the light has been absorbed.
In England, they are used among patients above 65 years old and critical patients who need regular monitoring. It is recommended to measure the oxygen levels of patients three times each day.
Once the reading shows lower than the normal 95%, one can then call their doctor. Studies have shown that dropping oxygen levels below 95% poses a risk to the person. Dr. Inada-Kim said that nothing beats early detection so that timely intervention will be administered to the patients.
Testimony from a COVID patient
Chris Harris, a 70 years old COVID-19 patient, was one who benefited from using the device. Last November, he was treated for a urinary infection but when he developed flu-like symptoms his doctor immediately sent him for COVID testing.
The positive result that came was quite stressful and frightening for him, as he narrated. When he was admitted he was still feeling fine but things suddenly changed the day after. He acquires a high temperature and his oxygen levels are getting lower. Chris was treated and experienced full recovery even if he was not placed in intensive care.
He said that it was the oxygen meter that caused him to go to the hospital. Thanks to the pulse oximeter. If he did not know his oxygen level perhaps, he did not go to the hospital earlier.
Dr. Inada-Kim though said that there is no definitive evidence yet to show that the gadget can indeed save lives. However, the early signs it gives to COVID patients have helped in the timely intervention.
