Not really maybe
Quite a dangerous picture someone put together and i would hate seeing one actually doing it as the picture portrays.
First of connecting the tubing with hot glue and tape is obviously not really reliable, it may work but a good tug and it may come right of.
The suggested helium tank on the picture is ballon time helium, which is notoriously famous here as the 80% helium only and is not near enough of purity.
The CPaP mask pictured doesn't provide a good enough seal to keep outside air from contaminating the low oxygen environment.
All these flaws combined of the suggested method would probably only result in you sitting and feeling stupid, nothing other than a faster heart rate would come of this.
