outstretch
To extend by stretching.
transitive
She knew from avalanche safety courses that outstretched hands might puncture the ice surface and alert rescuers. She knew that if victims ended up buried under the snow, cupped hands in front of the face could provide a small pocket of air for the mouth and nose. Without it, the first breaths could create a suffocating ice mask.
