[Aus-soaring] CADO versus Hypobaric hypoxia
One paper (see below) concludes that Combined Altitude Depleted Oxygen (CADO) is just as effective a tool for hypoxia awareness training as hypobaric hypoxia. It could be said that an explosive decompression is not a usual scenario for glider pilots at altitude (unless you are in a pressurised cockpit for extreme altitude flights), hence a gradual 'physiological ascent' by turning down the oxygen ratio will simulate the insidious nature of hypoxia during an ascent more realistically. Decompression chambers have been associated with occurrences of the bends, I know of one person who had the bends following a chamber run.

Re: [Aus-soaring] CADO versus Hypobaric hypoxia
But then again, there is this presentation that say there are differences between normobaric hypoxia (i.e breathing oxygen poor mixtures at sea level pressure), CADO (in a chamber at 10,000' altitude breathing an oxygen poor mixture) and hypobaric hypoxia ( HH i.e full chamber to 25,000'). It depends whether you want to know what you hypoxia symptoms (in normobaric and CADO) are versus the rapidity of onset in HH (to reinforce the urgency of the situation). Thinking back to my previous post, one cause for sudden hypoxia for glider pilots would be a sudden malfunction of the oxygen supply system or running out of O2! http://www.amma.asn.au/amma2011/downloads/Smith%20-%20Hypoxia.pdf ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
