How can you prevent someone who's paralyzed from getting bed sores?

See below: By being meticulous with bedcare.

Cause and effect: Bedsores are caused by pressure that damages the tissues. Unless you can float, pressure relief is impossible.

Good nutrition, keeping the skin moist and healthy, keeping bony areas away from themselves helps.
