Respiratory Gas Shifts to Delay Asphyxiation in Critical Avalanche Burial

Does a novel device delay the onset of hypoxemia and hypercapnia during critical avalanche burial by enhancing airflow to users’ airways?Median burial durations were 35.0 minutes in the intervention group, with no events (defined as Spo <80%), and 6.4 minutes in the control group, with 7 events. The device demonstrated its efficacy in simulated burial scenarios delaying hypoxemia and hypercapnia, and stabilizing ventilatory and cardiovascular parameters.Integrating this innovative technology into personal avalanche safety equipment, alongside existing tools like avalanche airbags and transceivers, could increase survival rates by extending the time available for successful rescue.
