Pressure injuries are painful and slow to heal, but they are largely preventable. This guide explains how alternating-pressure mattresses, well-matched cushions and a simple repositioning routine work together to protect skin.
Frequently Asked Questions
How often should someone be repositioned?
Every two to four hours is a common starting point, but the right interval depends on the individual's risk level, skin condition and the equipment in use. Follow the guidance of the treating clinician.
What is the difference between a static and an alternating-pressure mattress?
A static mattress spreads weight across a larger surface area. An alternating-pressure mattress actively inflates and deflates cells in cycles, so no single area stays under load — generally recommended for higher-risk users.
Do wheelchair users need a pressure cushion too?
Yes. Seated pressure concentrates over a small area, so a pressure-relief cushion matched to the user's weight and risk level is as important as the mattress used at night.
