You are on the right track, partial pressure is a very hard subject to get your head around, I know saruration divers that dont have a clue about it, it sometimes gets me confused and I have been a comercial diver / supervisor / superintendent for near 40 years, breathing at a partial pressure of 1.6 would bring on oxygen poisoning after a while
Correct answer is a PP of .21 normal PP for a working diver is between .4 & .6 but most bail out bottles would give a PP of 1.6 to 2 but that is for very short periods
Formula for working it out is depth x percentage O2 devided by 100
Cheers
