How do oxygen concentrators work? During a pulse oximetry reading, a small clamp-like device is placed on a finger.
The viral respiratory disease that affects the functioning of our lungs, often causes oxygen level in the body to drop to dangerous levels.
It concentrates the oxygen, which is then dispensed through a pressure valve that regulates the flow to the nasal cannula.
Seek medical attention if saturations drop or if any concerns arise.
Does this mean that anyone who finds their oxygen level falling below acceptable levels can use a concentrator and help oneself? The filters need to be replaced periodically, in such cases.
Even if COVID-19 therapies save more lives now than they could back in March and April, some patients might need weeks of hospitalization to recover from COVID-19 complications and get off of oxygen and ventilation machines.
