Jeez. I can barely breathe in one of those paper masks for long.
I’d faint being forced to wear an N95 all day.
Really good N95 and better systems sometimes use an electrical air pump to deliver air through the filters...
Spend several hours straining to draw air in through a
proper mask and it wears your ass out!
My o2 sat goes down to 92 when I wear one of those stupid
paper masks...to much rebreathin’ a goin’ on...
When I have all the gear on appropriately - N95, face shield, gown and gloves i’m good for 10-15 minutes tops. It is exhausting. And hot.
