Hi Tech, Wireless Help for Climbers

Mark Baard writes "Alpinists may soon be using wearable sensors and tricorder-like medical scanners to bail out their buried comrades. Computer scientists Bernt Schiele and Florian Michahelles, at the Swiss Federal Institute of Technology, are designing A-Life, a portable device that transmits and receives avalanche victims' vital signs through snow, up to 80 meters away."

Knowing a Victim's Vitals Good For Rescuers

[n8]

I have been a ski patroller at a small local area for 9 years now and I had the unfortunate privelidge of being on the mountain when a fellow ski patroller was killed in an avalanche during Avalache Control. What nobody knew at the time was that the patroller that was killed was buried in such a way that he had no air pocket and most likely died within the first 3 minutes of being buried. Yet, the rescue team put themselves into a position where they were attempting save someone in very hazardous avalanche conditions who was actually already dead. The rescue team actually set off more avalanches accidentally and partially buried members of the team.

Rescue attempts like this are always extremely dangerous for the people involved. If they had some way of knowing whether the person was alive it would be very valuable information when trying to make the decision whether or not to risk other people's lives in order to save a buried person.
