Patient Education: Alternating Air Mattress
What is an Alternating Air Mattress?
An alternating air mattress is a special bed that helps prevent or treat pressure ulcers (bedsores). It has air cells inside that fill and empty with air in turns. This gently shifts pressure from one area of the body to another. By doing this, the mattress helps protect the skin and improve comfort for patients who must spend a lot of time in bed.
Purpose of the Mattress
Helps prevent bedsores by reducing pressure on the skin.
Improves blood flow by changing pressure points.
Increases comfort for patients who cannot move often.
Safety and Use
1. Power and Electricity
The mattress needs electricity to run the pump.
If the power goes out, the mattress will flatten. A flat mattress will not protect the skin.
During a power failure, caregivers must turn and reposition the patient at least every 2 hours to prevent skin breakdown.
Keep an extra blanket or cushion ready in case the mattress deflates.
2. Repositioning is Still Needed
Even though the mattress helps, patients should still be turned and repositioned often.
Heels should be “floated” by placing a pillow under the lower legs so the heels do not touch the mattress.
Arms, hips, and back should be checked often for redness, warmth, or open skin.
3. Daily Care
Keep sheets wrinkle-free and dry. Wrinkles or moisture can increase skin breakdown.
Do not place extra pads, heavy blankets, or plastic under the patient, as this can block airflow.
Check the pump daily to make sure it is running properly. You should feel the air cells inflating and deflating.
4. Safety Around the Bed
Keep cords out of walkways to prevent tripping.
Make sure the pump is plugged into a safe outlet, not overloaded with other devices.
Keep food, liquids, and pets away from the pump.
Important Reminders for Families
An alternating air mattress is a tool to help prevent bedsores, but it does not replace good nursing care.
Patients still need to be turned, positioned, and checked regularly.
Report any new skin redness, open areas, or pain to your nurse or doctor right away.

TRUE OR FALSE: During a power failure, patients must still be turned and repositioned often.
TRUE OR FALSE: Heels should be floated with a pillow under the lower legs.
TRUE OR FALSE: The mattress replaces the need for turning and positioning.
TRUE OR FALSE: Sheets should be smooth and dry to protect the skin.
TRUE OR FALSE: Wrinkled sheets can cause skin breakdown.
TRUE OR FALSE: It is safe to put heavy blankets or plastic under the patient on this mattress.
TRUE OR FALSE: The pump must be plugged in for the mattress to work.
TRUE OR FALSE: You should check the pump daily to make sure it is running.
TRUE OR FALSE: Repositioning is important even with the mattress.
TRUE OR FALSE: A flat mattress during a power outage will not protect the skin.
TRUE OR FALSE: Pets and liquids should be kept away from the pump.
TRUE OR FALSE: If you see redness or open skin, you should report it to your nurse or doctor.
TRUE OR FALSE: The mattress should be kept against the wall for stability.
TRUE OR FALSE: Cords should be kept out of walkways to prevent tripping.
