And those with chronic health issues also see no problem with masks, despite having existing pulmonary conditions:

Basically, the volume of air that your lungs can move, in addition to the force of exhaling/inhaling, easily overcomes any air "trapped" in the mask.

CO2 is addressed. > You can hyperventilate until you pass out without your blood oxygen saturation changing. Passing out when you hyperventilate is from too little CO2 rather than “retention.“ The opposite of what is being claimed masks cause.
- phonypc 6y agoI did watch the first video in full; the other link, and three others in another post only address blood oxygen. I made no claims about CO2. I don't think wearing a mask will meaningfully affect the breathing of most people, but blood oxygen isn't meaningful in demonstrating as much. Passing out from hyperventilation is a second order effect of hypocapnia; the proximate cause is cerebral hypoxia, despite the blood being saturated.
