First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a soda lime canister can remove carbon dioxide from the air pocket that forms around a person buried in snow. In an avalanche, the air pocket quickly fills with exhaled CO2, leading to suffocation. 22 healthy volunteers breathed into a simulated snow air pocket with and without the soda lime device. The goal was to see if the device could delay dangerous CO2 buildup and low oxygen levels, potentially increasing survival time.
