Root Cause

Digging a hole in the snow after avalanche burial rapidly depletes the limited air pocket and exhausts the victim; the correct action is to create an air pocket in front of the face and remain still to conserve oxygen.

雪崩掩埋后在雪中挖洞会迅速耗尽有限的空气囊并使受害者精疲力竭；正确做法是在面前制造一个空气囊并保持不动以保存氧气。

Workarounds

  1. 80% success As the avalanche slows, cup one hand over your mouth and nose to create an air pocket. When burial stops, remain still and calm to conserve oxygen.

Dead Ends

Common approaches that don't work:

  1. Dig vigorously to create a large cavity 98% fail

    Exhaustion and rapid oxygen depletion lead to unconsciousness within minutes

  2. Swim upward to try to reach the surface 85% fail

    Avalanche debris is too dense; swimming wastes energy and oxygen

  3. Shout for help continuously 90% fail

    Shouting wastes oxygen and sound is muffled by snow; rescuers use transceivers
