FIREFIGHTER ENDS MASK DEBATE ONCE AND FOR ALL
Masks are not Respirators This was a Dilettante Presumption Theorem: All statements of fact, opinion, or analysis expressed do not necessarily reflect official positions or views or any other entity, past or present. Nothing in the contents should be construed as asserting or implying endorsement of interpretations and factual statements.
baa, baa, bleating little sheeple.
This is plain wrong, misleading and irresponsible. The dead space within the mask will indeed contain a very small quantity of air with reduced level of O2 as you exhale, nominally 16%, but is immediately replaced with a very large volume of fresh air at 20-21% O2 when inhaling. Your mouth, nose and airways also contain exhaled air at 16% O2 even when not wearing a mask but you don't seem worried about that. The effect of dead space in breathing apparatus facemasks (or other types of masks) is well understood (hence use of ori-nasal inserts in full face masks) and you should do your homework before publishing fake and dangerous stories.
i know that covid is a big lie. but to make this vudeo is not doing us any good. As you breath in, are you reslly trying to say that a mask filters out oxigen.. i think not.
It's showing how the carbon monoxide/dioxide ratios are affected by the mechanics of the mask.
Ummm, look up waterboarding.
Are you on pills? With the mask ON, you are not able to INHALE as much oxygen because you have something BLOCKING your airway
I have had to come back because I have seen tonight on tv there getting people to use these little machines to measure your blood oxygen because they say it is very low if you are a carrier of covid honestly you couldn't make it up your blood oxygen is low because your wearing masks are they real or is it me .
