A strange phenomenon caused the sudden death of Covid-19 patient

Many people with nCoV still talk and walk normally, but the blood oxygen level is so low that it can cause unconsciousness or death at any time.

Experts call this the "silent hypoxia" phenomenon , which occurs when the person is unaware of their lack of oxygen. Most people are hospitalized with health much worse than they imagined.

Typically, these patients exhibit Covid-19 symptoms for two to 7 days before coming to the hospital. They "feel chest tightness or cannot breathe deeply," said Dr. Richard Levitan, Littleton Health Center, New York City.

He spent nearly two weeks volunteering in the emergency room at the epidemic center. There, he monitored patients hospitalized with 50% blood oxygen levels, so low that they could cause unconsciousness, speaking poorly. The results of a pulmonary scan showed a serious sign of inflammation, which should have been painful, causing the patient to gasp.

"X-rays looked terrible. But they were fully awake, able to use cell phones. They were all sick for days. But only recently have they felt short of breath, tired and having problems." other problems, " says Dr. Levitan.

This is a dangerous phenomenon because when people infected with nCoV notice abnormal signs of breathing, the disease is already in a very serious stage.

"Some even use ventilators. The concentration of carbon dioxide increases, the fluid accumulates in their air pockets, their lungs harden, leading to acute respiratory failure," he added.

Doctors surmise that for some people, the symptoms of Covid-19 do not progress quickly. Dr. Cedric Rutland, American Lung Association, explained that when oxygen levels drop significantly, the body will automatically compensate by increasing breathing and patients get used to the speed. Many people are not aware of this and do not seek the help of a doctor.

By the time they were hospitalized, serious injuries had occurred, not only with the lungs but also with many other organs such as the heart, kidneys and brain. The situation of "silent hypoxia" may explain some cases of young patients without background disease, nCoV infection and sudden death.

In the early stages of the pandemic, almost all patients were given ventilators after hospitalization. Currently, your physician is trying to find an alternative such as an oxygen mask or to adjust your lying position. Experts say this benefits both health care workers and patients.

To connect a ventilator, the doctor must put an intubation. The process is not pleasant. Many people have to use sedatives to keep the catheter from falling asleep. Mechanical ventilation can also lead to infections, pneumonia or blood clots.

To avoid the "silent hypoxia" phenomenon , Dr. Richard Levitan called for an early diagnosis by giving mild symptomatic Covid-19 patients using a blood oxygen meter during two weeks of isolation. He also suggested that people measure the index at home by hand-held devices, quickly go to the hospital if there are signs of abnormality.

However, the problem is the accuracy of the personal gauges marketed. A 2016 study found that only 30% of the devices tested met the International Standards Organization's criteria.
