OK, I am a master scuba instructor. (seriously)
No is your answer, that would not work for many reasons. Hold your breath for 1.5 min? OK, but after doing that you will gasp and take several deep breaths to compensate for the O2 shortage, that's just physiology. BTW, the number one rule of breathing (<--key word) compressed air is you NEVER HOLD YOUR BREATH.The only thing near what you are talking about is Snuba, where there is compressed air on the surface and you are tethered with a hose. (think commercial diver without all the gear.)
If you hold your breath while breathing compressed air you are asking for trouble. The depths you would be diving would probably be in the 30' depth area, which are the most dangerous as volumes double in that first ~33'. (I think it's 0.45psi per foot, in saltwater) Imagine if you are in 10'swells and you are right under one when you take a deep breath at 10'. While the swell is over you you are now at 20' and don't even know it, as it passes you are immediately back at 10', a huge pressure change quickly. That's why I teach my divers to take medium breaths and not filling their lungs up all the way when doing beach entries and swimming out under waves and swells.
What you want to do would be dangerous, not to mention you would need to be certified to by compressed air...even a pony bottle. Take a scuba class and just go scuba diving, you can stay down for an hour easily at shallower depths and it's very relaxing.
