Root Cause

Shouting when buried in snow wastes precious oxygen and sound is muffled by snow, making it ineffective; rescuers use transceivers and probes, not hearing.

被雪掩埋时大声呼救会浪费宝贵的氧气，且声音被雪层阻隔，无效；救援者使用信标和探杆，而非听觉。

Workarounds

  1. 80% success Create an air pocket by cupping hands over mouth before snow settles, then remain still to conserve oxygen. Use an avalanche transceiver (beacon) for signaling.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Shouting causes hyperventilation and CO2 buildup, reducing consciousness time from ~15 min to under 5 min.

  2. 90% fail

    Snow absorbs sound; even a 1m depth muffles shouts to inaudibility for rescuers >2m away.
