Alternate™/Mighty Air™

Alternation Low Air Loss

Alternate, and its bariatric counterpart, Mighty Air, offer active pressure redistribution with 1-in-3 alternating pressure. The surfaces’ low air loss capability and high-tech fabric combine to help control patient microclimate, while immersion mode promotes proper envelopment. Both surfaces are sized to fit most Med-Surg and ICU bed frames.

Two Therapy Modes

1-in-3 alternation provides optimal pressure redistribution by dropping every third cell during the programmed cycle times (3 to 20 minutes). In immersion mode, the 4-way stretch top cover allows for optimal envelopment, as the patient comfortably sinks into the surface.

Low Air Loss

Laser-cut holes in the air cells provide constant low air loss to support the patient microclimate—dissipating moisture and keeping the skin/surface interface cool and dry.

Patient Success Story

"It’s given me a better quality of life. It's allowed me to continue to work," said Mike. "It’s sped the time up almost double as far as the healing’s concerned."

Fabric Characteristics

breathable icon

Breathable: The specialized top cover fabric promotes airflow for improved patient microclimate but remains resistant to fluids.

low friction icon

Low Friction: A quilted inner layer partners with the top cover to reduce friction and shear—enhancing patient comfort and healing.

advanced chemical resistance icon

Advanced Chemical Resistance: Cover fabrics are highly chemically resistant and RF-welded—two factors that support infection control and prevention.

A pressure ulcer/injury is localized damage to the skin and/or underlying soft tissue, usually over a bony prominence or related to a medical device. The injury can present as intact skin or an open ulcer and may be very painful.
