Indeed. I routinely wore a surgical mask for many hours at a time back when I still did general surgery. There are still occasional cases I do that last 4-5 hours. No problem.https://twitter.com/DocMCohen/status/1259951546004987904 …

“Continual” mask wearing is, of course, not defined in any of these dysinfo memes.
Are we talking about a 20 min trip to Costco? Or a 9 hr surgical procedure where surgeon, anesthetist and nurses all wear masks throughout?
Guess what? Neither case leads to hypercapnia. 7/ pic.twitter.com/nerQ9zFD3C
