How do air mattresses help?

Alternating air mattresses help to prevent this from ever occurring in the first place. They are often referred to as anti-decubitus mattresses.

By using different activities and modes, the air actually stops pressure build-ups from happening.
Consequently, this slows down any pressure injuries taking hold and promotes better circulation in vulnerable areas of the body.

Alternating air mattresses can offer pressure relief or pressure redistribution.
