In the event of burial by an avalanche, the probability of survival is significantly reduced after just a short time under the snow cover. Despite the increasing use of avalanche equipment and airbag backpacks, the mortality rate is still around 13%.
Although airbag backpacks reduce the probability of (full-body) burial, they are of course no guarantee of survival in the event of an avalanche. In the event of a burial, in addition to injuries caused by falling and blunt force trauma, the risk of suffocation due to lack of oxygen is a decisive risk factor. The exhaled air contains a high proportion of carbon dioxide, which in turn is inhaled and, in extreme cases, causes the victim to suffocate.
This is precisely where the Advenate IAS system comes in: The breathing system separates the inhaled air from the exhaled air and releases it to the outside through a tube system at the bottom of the backpack. The release handle of the airbag system acts as a mouthpiece, which is inserted into the mouth in the event of an avalanche and fixed in the mouth like a snorkel. This means that both rescue systems can be activated simultaneously. The separation of "used" air and fresh air guarantees up to 60 minutes of breathing time, according to the manufacturer. In addition, the Alpride airbag system with a volume of 150 liters provides sufficient buoyancy to prevent burial altogether if possible.
