Divers probably know more about air and mixed gases than most of the general public, because that understanding forms an integral part of the training required for diver certification.
For example, did you know that oxygen becomes toxic at depth?
Breathing air with a higher than normal percentage of oxygen can cause convulsions and even death at more than 33 meters of depth.
But divers do exploit the benefits of oxygen enriched air when diving at more conventional depths and they call the enriched air “Nitrox.” You can pre order nitrox from most dive centers and most diving boats, with anything from 34% up to 40% oxygen. I know from personal experience how beneficial nitrox is, having dived four times a day using it in The Red Sea for ten days. Diving is hard work, and the depth takes a real toll on your body – I know I would have been exhausted with that schedule using plain old air.
Divers also learn early on in their training that oxygen is essential for any diving related issues. For anything from a post diving headache to a serious case up DCS (The bends) the recommended treatment is to get the diver straight onto oxygen.
If you’re diving with a dive school, it may well be that they carry medical oxygen, but if they don’t or you are diving privately, then get yourself a can of Booost and keep it in your dive kit. It’s no substitute for medical oxygen, but it may well help to increase personal oxygen levels while waiting for the emergency services. And a few puffs taken after a dive can help that feeling of tiredness we all get post dive.
Booost canned oxygen will be available late January/early February. kirkscubagear is proud to be the supplier of Booost in Canada.
