A group of 36 volunteers were ‘buried’ alive during a study for science. The new clinical trial has found that a user-carried avalanche safety device can prevent hypoxemia and hypercapnia for a significant amount of time in case a person is trapped alive under snow and debris. This can be critical in life and death situations. The volunteers’ safety was, of course, monitored constantly and were taken out as soon as their health parameters showed signs of dropping below a certain level.

The randomised and blinded study was conducted at a field site in Italy between January and March 2023. The test evaluated a novel airflow device designed to channel air from surrounding snow to the user’s airways. Unlike conventional systems, it operates without supplemental oxygen or a mouthpiece.
