One of the mysteries of Covid-19 is why the oxygen content in the blood may drop to dangerously low levels without the patient noticing it.

One of the mysteries of Covid-19 is why the oxygen content in the blood may drop to dangerously low levels without the patient noticing it.
As a result, the health of patients after admission is far worse than they thought, and in some cases it is too late for effective treatment.
However, in the form of a pulse oximeter, a potentially life-saving solution could allow patients to monitor their oxygen levels at home, at a cost of approximately £20.
They are rolling out to high-risk Covid patients in the UK, and the doctor who leads the plan believes that everyone should consider buying one.
Dr. Matt Inada-Kim, consultant emergency medicine at Hampshire Hospital, said: “With Covid, we allow patients to enter low oxygen levels in the 70s or 80s.”
He told BBC Radio 4′s “Internal Health”: “This is really a curious and frightening demonstration, and it really makes us rethink what we are doing.”
The pulse oximeter slides on your middle finger, illuminating light into the body. It measures how much light is absorbed in order to calculate the oxygen level in the blood.
In England, they are given to Covid patients over 65 who have health problems or any doctor’s concern. Similar plans are being promoted across the UK.
If the oxygen level drops to 93% or 94%, people will speak to their GP or call 111. If it is less than 92%, people should go to A&E or call a 999 ambulance.
Studies that have not yet been reviewed by other scientists have shown that even less than 95% of small drops of water are associated with an increased risk of death.
Dr. Inada-Kim said: “The focus of the entire strategy is to intervene as soon as possible by putting patients in a more salvageable state to prevent people from developing this disease.”
In November last year, he was treated for a urinary tract infection, but then he developed unexpected flu-like symptoms and his general practitioner sent him to undergo a Covid test. This is positive.
He told “Internal Health” magazine: “I don’t mind admitting that I was crying. It was a very stressful and frightening time.”
His oxygen level was a few percentage points lower than the normal area, so after a phone call with his general practitioner, he went to the hospital.
He told me: “My breathing started to become a little difficult. As time passed, my body temperature increased, [my oxygen level] gradually decreased, reaching more than 80 years old.”
He said: “As a last resort, I might have gone to [hospital], it was a frightening thing. It was the oxygen meter that forced me to go, and I was just sitting there thinking that I would recover.
His family doctor, Dr. Caroline O’Keefe, said she has seen a significant increase in the number of people being monitored.
She said: “On Christmas Day, we are monitoring 44 patients, and today I have 160 patients being monitored every day. So of course we are very busy.”
Dr. Inada-Kim said that there is no conclusive evidence that gadgets can save lives, and it may not be confirmed until April. However, the early signs are positive.
He said: “We think what we are seeing are early seeds for reducing the length of stay after hospitalization, improving survival rates and reducing the pressure on emergency services.”
He believes very much in their role in solving silent hypoxia, so he said that everyone should consider buying one.
He said: “Personally, I know many colleagues who bought pulse oximeters and distributed them to their relatives.”
He recommends checking whether they have CE Kitemark and avoiding using apps on smartphones, which he said is not that reliable.
Government scientists promised after the successful jab operation that Britain will soon enter a “very different world”.
