3. Figure 2
(A) The artificial breathing device (AvaLung, Black Diamond Equipment, Salt Lake City, UT) used during snow burial is shown. White arrows show flow of inspiratory air and dark arrows show flow of expiratory air. The subject breathes in and out through the mouthpiece (A). Inhaled air enters from the snowpack through the one-way inspiratory valve (B) on the side of the housing inside the mesh-protected harness on the chest. Expired air leaves the lungs through the mouthpiece and travels down the respiratory tubing to the housing and then passes through an expiratory one-way valve located at the bottom of the housing (B) and travels through respiratory tubing inside the harness around to the back (C). (B) A backpack with a built-in AvaLung (Covert AvaLung Pack, Black Diamond Equipment).

Participant responses to the following survey questions in the (A) Wasatch range and (B) Teton range. Question 10: How much will an avalanche air bag improve survival if caught in an avalanche? Question 11: How much will an AvaLung improve survival if caught in an avalanche? Dotted bars indicate AvaLung; hatched bars indicate air bag. The x-axis represents the multiple choice answers offered to the participants on the survey. The instructions were to circle one of the possible answers only. The y-axis demonstrates the number of responses.
