In relation to the above, an article from the NY Times: What Doctors on the Front Lines Wish They’d Known a Month Ago
Some patients, by taking oxygen and rolling onto their sides or on their bellies, have quickly returned to normal levels. The tactic is called proning.
Doctors at Montefiore Medical Center in the Bronx and Mount Sinai Medical Center in Manhattan have described it on Twitter; a flier is posted next to beds at Elmhurst Hospital Center in Queens as a guide for patients on how often to turn themselves.
At Lincoln Hospital in the Bronx, Dr. Nicholas Caputo followed 50 patients who arrived with low oxygen levels between 69 and 85 percent (95 is normal). After five minutes of proning, they had improved to a mean of 94 percent. Over the next 24 hours, nearly three-quarters were able to avoid intubation; 13 needed ventilators. Proning does not seem to work as well in older patients, a number of doctors said.
