What Is Air Fluidized Therapy?
Air Fluidized Therapy (AFT), often called a "sand bed," is a specialized Group 3 support surface designed for patients with severe pressure injuries and complex wound care needs. Using millions of tiny ceramic beads suspended by warm filtered air, the mattress creates a fluid-like surface that allows patients to float while remaining fully supported. AFT allows patients to experience:

Maximum Pressure Redistribution
Helps reduce pressure on vulnerable areas and supports wound healing.
Reduced Friction & Shear
Protects fragile tissue and helps minimize additional skin breakdown.
Support for Complex Wounds
Often prescribed for Stage III and Stage IV pressure injuries and flap procedures.
Advanced Clinical Support
Designed for patients whose wounds require the highest level of pressure relief.

Who May Benefit from Air Fluidized Therapy?
Air Fluidized Therapy may be appropriate for patients experiencing:
- Stage III pressure injuries
- Stage IV pressure injuries
- Multiple pressure injuries
- Non-healing wounds
- Flap or graft procedures
- Complex wound care needs
- Failure to progress on a qualifying Group 2 support surface
Our team can help determine eligibility requirements and assist with insurance review and documentation collection.
