The conclusion that N95 masks cause CO2 build-up can not be made with the data shown. The only comparison we get is a baseline resting CO2 levels and a mask-wearing result whilst exercising. There is no result comparing CO2 levels whilst exercising with a mask and without a mask. Without this, your conclusion is just an assumption. Further testing with actual control variables would be required.
What about respiration rate or other measures of the difficulty of breathing? Is there a change in the effort needed to breathe while wearing a mask even though the outcome for O2 levels in the blood remains nominal?
Thanks for all your efforts here – it’s all refreshingly useful!
Just an observation. You note a modest rise in paCO2 but above that comment in the article about nurses during a 12 hour shift, in the non-highlighted portion of the excerpt you display, that study showed a more significant rise in paCO2 of about 10 mm.
