More up to date North American stats also show that many more people die from two of the triple "H" than was thought. Hypoxia and Hypercapnia kill quickly, even folk dug out very fast getting advanced life support don't often survive.
Triple "H" syndrome is Hypoxia, Hypercapnia (i.e re breathing your own carbon dioxide) and Hypothermia.
Hypothermia can have a protective effect in rapid cold water immersion, but in an avalanche cooling is slow, especially as modern clothing retains heat so well. In fact its not so much the lack of oxygen as the hypercapnia that makes survival so poor in a an avalanche, and this with hypoxia is also related to snow density). 15 minutes as often shown in survival graphs is quite optimistic. You need to search fast and dig faster (which means practise these skills more) as time is not on the victims side.
When dropping in stay next to each others tracks, go one at a time well spaced and from a safe area to safe area. What's a safe area? Good question as sometimes there are none, but basically its somewhere out of any slide path that you can identify. Consider that if its a big slide it could encroach on your safety island so pick your spot with care.
Be prepared to carry out a rescue. You are on your own as organised rescue will be too late. Talk this over before dropping in. You should all have done an avy course and so will have the gear, done the pre checks and discussed a plan - won't you? If you have not done an an avy course then consider why the feck are you even doing this!
