I thought that the hyperventillating was to get rid of excess CO2, not necessarilly build up extra O2. But, then again, I'm not really up on this at all, so I could be very wrong.scubamate:Along with what rab stated, you can hyperventillate yourself 2-3 quick deep breaths to build up extra O2 This should enable you to stay under longer. Don't over hyperventillate as it can cause you to pass out, and passing out in the water isn't a good thing.
True. Hyperventilation suppresses the build up of CO2 to the point where the urge to breathe is delayed. This is a dangerous activity. Through normal deep ventilation you can have an efficient gas exchange and feel "enriched" with a lungful of air. A minute underwater is more than enough time to explore and enjoy what there is to see. Your best bet is to stay within your comfort zone, practice and continue to gain comfort in the water. Refrain from hyperventilation. Keep a qualified partner on hand esp. during any in-water activities. The safest way to enhance your breath hold is to train your cardio-respiratory systems. Once you have attained a level of satisfactory fitness here, then you might begin some specificity training. Just keep posted and keep posting!cmalinowski:I thought that the hyperventillating was to get rid of excess CO2, not necessarilly build up extra O2.
