Changes in systemic carbon dioxide levels during simulated avalanche burial using a one-way valve device: a randomized, double-blind, crossover trial.

Key Points

• To assess changes in systemic carbon dioxide levels during avalanche burial using a one-way valve device.
• Conducted a randomized, double-blind, crossover trial
• Monitored systemic carbon dioxide levels during simulated avalanche conditions
• Terminated per protocol or when safety criteria were surpassed
• Increased carbon dioxide levels through one-way valve device
• Markedly prolonged burial time with the device
• Desaturation of oxygen prevented in the monitored group
