Did you feel a headache or any pain (during or after)?


Oh maybe I should get a co2 sensor too, didn't know that exist! Did you get 2-in-1? I only have an oxygen meter rn but bit worried about co2 too.

No all in one. Easy to get for co2. O2 is a little expensive

Did you feel a headache or any pain (during or after)?

After yes, for the last attempts

Ya suppose it is,just some little tricks need to be careful about like you should squeeze all air out of the bag before you pump in inert gas n breathe out as much as you can before pull your head into the bag,both ensure no O2/Co2 wouldn't involve

Hi, sorry, how is it possible to squeeze all air out the bag? I read you have to put your head in the bag but that it doesnt have to stick to your face, so possibly it has air in it ? Or maybe i don't understand the process
Thank you
