What is an Oximeter?
A pulse oximeter slips over your middle finger and shines a light into the body. It measures how much of the light is absorbed in order to calculate oxygen levels in the blood.
Why it is important to have access to one.
One of the mysteries of Covid-19 is why oxygen levels in the blood can drop to dangerously low levels without the patient noticing. It is known as “silent hypoxia”.
As a result, patients have been arriving in hospital in far worse health than they realised and, in some cases, too late to treat effectively.
A normal oxygen level in the blood is between 95% and 100%. If oxygen levels drop to 93% or 94%, then people speak to their GP or call 111. If they go below 92%, people should go to A&E or call 999 for an ambulance.
Studies, which have not been reviewed by other scientists, have shown even small drops below 95% are linked to an increased risk of dying.
With Covid-19 still to be around for some time to come it is important that all families in Stinchcombe have access to one in case of catching the virus.
I have one at home – unused and in the box. So if you come down with the virus, just drop me an email. – Richard
