Question asked
on 1/25/2014
I'm a surfer and I use a portable Oxygen Concentrator when exercising on land. I have a recommendation from my Pulmonologist to use a 3 liter setting for my oxygen concentrator. For surf contest I would like to have a X treme sport Noprene vest and a Nitrox Back up supply is that doable? Do I need a prescrption? What Nitrox product is comparable to a 3 liter setting? Is the nitrox refillable at my local dive shop ? They say that the cylinder must be right and they need a Dr's prescription.

OK, first off these are filled from an existing tank so doing nitrox would not be a problem you would need a certification unless the dive shop you are dealing with will take your prescription since this is not for scuba. As for a 3 liter setting you would need calculate to percentage of O2 in the tank. Hope this helps!! Thanks, Bill
