I own a pulse oxymeter to which the doctor refers in this article. It’s available at most drugstores or online, not expensive and easy to use. The readings are immensely valuable if you are worried about breathing issues, your heart or have a history of dementia in your family — and now if you’re worried about the corona virus. It turns out that like every other disease, early detection is the best treatment.
The article is written by a doctor who volunteered to treat Covid19 patients at Bellevue Hospital in New York.
