Volunteers Buried in Snow for Science
A clinical trial of a safety device, which channels oxygen to a buried person's face, suggests it may improve avalanche survival.
When a person is trapped in an avalanche, there is very little time before their oxygen supply runs out.
A new safety device that channels air to the buried person's face may extend survival and increase the chance of a successful rescue.
- Participants were buried face-down under at least 50 centimeters of snow.
- The goal was to remain there safely for 35 minutes.
A safety device helped maintain a buried person's oxygen levels for up to 35 minutes, tests show, buying crucial time for an avalanche rescue.
Avalanche rescuers take part in a training exercise at a ski resort in the French Alps.
