A new avalanche backpack will increase a victim's survival window from 15 To 90 minutes.
Avalanche caused deaths don’t result from a lack of oxygen. Dense avalanche debris sits at around 60-70% air. Victims succumb to carbon dioxide poisoning as gas builds up in the snow around them. The SBX seeks to limit that carbon dioxide buildup by pumping oxygen into the snow surrounding one’s mouth while pushing away the built up carbon dioxide. In an avalanche a victims pull the t-shaped handle located on the shoulder strap. This activates a fan located in the SBX Clean Air Intake placed on one’s back. That fan pumps oxygen from an area lacking CO2 buildup to the Clean Air Outlets on the wearer’s shoulders.
