Video Presents Flawed Test on Masks, Oxygen Levels - FactCheck.org
A viral video questions the safety of face masks by using a gas detector to purportedly show that masks result in dangerous oxygen levels for the wearer. But experts -- and the company that makes the gas detector -- say the video's testis scientifically flawed.

I have had clients tell me they don't get enough O2 with a mask on. I debunk that easily with a pulse oximeter which measures the lercent O2 in your blood. Hardly anyone has dropped their SAO2 from breathing normally without a mask to wearing it. The ones that dropped, dropped only 1%. Sorry, I don't buy this one.

SFC Bernard Walko many of these individual clients have chronic lung disease but still maintain their oxygenation with their masks on.

Its like this. Surgeons in surgery wear masks for hours and if they were deprived of oxygen they could not do surgery for hours. In MOPP 4 we don't pass out. Now what a lot of people experience is claustrophobia. Feeling that mask over their mouth causes them problems and they may start to hyperventilate and they mistake that for not getting oxygen because of the mask.
To prove some FB friends wrong I grabbed my pulse/ox, put on 2 surgical masks and a K95 mask then started recording my pulse/ox readings. No change. 3 masks and no change. I did it with a surgical mask and a k95 mask outside in 105 degree heat and the result were the same. No problems whatsoever.
What we have is an attempt by others to undercut public health officials. For what reason I don't know but it is an act of idiocy.
