Do doctors and nurses ever wear vented masks during surgeries and other invasive procedures? In those cases, I assume that the mask is primarily meant to protect the patient from the doctors' and nurses' germs, so why wasn't this a concern in the pre-Covid days?
- azalemeth 6y agoUnless the patient presents a truly astounding infectious risk, almost certainly not. Surgical masks are not valved. However, the fact that theatres have a truly huge and mind boggling amount of air handling equipment on the floor above them, directing highly sterile and laminar air flow directly down to the floor from all angles, definitely does help this not matter as much...in an operating theatre, at least, not an aircraft.
