This social media claim has been studied and refuted as a significant problem. No study can prove it didn't happen once. Or that the nurse errantly applied the oximeter giving wrong numbers. But a study of elderly adults wearing non-medical cloth masks was done where multiple oxygen measurements were taken over three hours and there were ZERO persons who had hypoxia from wearing a mask. Peripheral Oxygen Saturation in Older Persons Wearing Nonmedical Face Masks in Community Settings | Geriatrics | JAMA | JAMA Network The study looked for a 2% drop in oxygen saturation. It didn't find one. The poster here claimed a 10% drop relieved by a couple breaths with no supplemental oxygen.
Sorry, but an oxygen saturation of 89 will never go up to 98 with a couple breaths within a few seconds. Measurement error or fabrication. |
Great post! Well written and informative, such clarity. Nice to know that there are so many thoughtful and clever people in TV Land. Impressive!
