A suspicious mystery about a strange condition affecting “Covid-19” patients confused doctors and led them to question the fundamental principles of biology.
It turns out that some Corona patients don’t seem to be really distressed, but have low enough oxygen levels to cause unconsciousness or even death.
This phenomenon, known to some as “happy hypoxia” (some prefer the term “silent”), raises questions about how the virus attacks the lungs and whether there can be more effective ways to treat these patients.
A healthy person is expected to have an oxygen saturation of at least 95%. But doctors report that patients entering intensive care with oxygen levels in the 1980s or 1970s, with some severe cases less than 50%.

“It is interesting to see how many people suffer from hypoxia. We see very low oxygen saturation and they don’t realize it,” said Dr. Jonathan Banard Smith, anesthesia and critical care consultant at Manchester Royal Hospital. Flu or pneumonia. It is much deeper and an example of abnormal physiology, which occurs before our eyes. “
Dr. Mike Charlesworth, an anesthetist at Wythenshawe Hospital in Manchester, said that while other lung conditions can cause severe hypoxia, these patients generally look very ill. He added: “With pneumonia or pulmonary embolism, they won’t sit on the bed to talk to you. We just don’t get it. We don’t know if it causes organ damage and we can’t detect it.”
Charlesworth had a personal experience of the condition, while suffering from “Covid-19” in March. After his condition worsened with a cough and fever, he spent 48 hours in bed, as there were signs that he was hypoxic, he said.
“I was sending very strange messages on my phone. I was completely delusional. Looking back, I should have gone to the hospital. I’m sure the oxygen levels were low. My wife said my lips were very dark. But I was probably with hypoxia, and my brain may not work very well. “
Mike recovered after a few days in bed, but he and others realize that not all cases have positive results.
An anesthesiologist at a London hospital, who spoke anonymously, recalled a patient who had come to the A&E Center saying she was cold. He said: “When we got the tracking devices in his body, his saturation was 30% of the air. We obviously thought this was a mistake, since patients are more likely to have heart conditions associated with hypoxia.” But when a blood sample was taken, it was discovered that the oxygen levels were the same as those observed in people who had adapted to high altitudes. The patient was placed on a ventilator and survived for a week before her death.

And with conventional medical wisdom, it says that as oxygen supplies decrease, the heart, brain, and other vital organs are at risk, and the effect is believed to be cumulative. Patients generally lose consciousness without oxygen saturation by 75%.
However, it is not the low oxygen levels themselves that make people feel short of breath. Instead, the body detects the high levels of carbon dioxide that generally occur at the same time, because the lungs cannot efficiently remove gas. But for some Covid-19 patients, this response doesn’t seem to have started.
Banard Smith said: “I don’t think any of us expect that what we see can be interpreted through a process.”
Swelling and inflammation in the lungs can make it difficult for oxygen to enter the bloodstream. There is also emerging evidence that “Covid-19” can cause blood clotting.
Some have suggested that since people are often unaware of low oxygen levels, people with Corona virus symptoms should receive a pulse oximeter, which is a simple device that connects to the finger and can be used to detect levels oxygen. However, there is still no evidence that early detection of hypoxia helps avoid severe results, and Charlesworth said the practicalities would be difficult.
