Fast Push #2: Safeback SBX for Avalanche Asphyxia Prevention
In this episode of Wilderness Medicine Updates, host Patrick Fink delves into groundbreaking technology designed to improve safety during avalanche events. The focus is on SafeBack SBX, a Norwegian-developed device that supplies air to users buried in avalanches, potentially extending survival time. Patrick reviews new research published in the Journal of the American Medical Association, which demonstrates significant efficacy in delaying hypoxia during simulated avalanche burials. The episode provides an in-depth analysis of SafeBack SBX, its mechanisms, study results, and its comparative and complementary role alongside existing safety technologies like airbags. Concluding with potential applications and limitations, Patrick aids listeners in deciding whether SafeBack SBX is a worthy addition to their avalanche safety gear.
