Breathing under snow e.g. while buried by a snow avalanche is possible in the presence of an air pocket but limited in time as hypoxia and hypercapnia rapidly develop. Snow properties influence levels of hypoxia and hypercapnia but their effects on ventilation and oxygenation in humans are not fully elucidated yet.
