The Invacare microAir Lateral Rotation Mattress offers the benefits Lateral Rotation, Alternating Pressure and On-Demand Low Air Loss. The MA90Z is a deep flotation therapy system that can directly replace specialty hospital beds.

The MA90Z is portable, and readily attached to most hospital and nursing home beds. The MA90Z replaces the mattress on standard medical beds. It provides continuous flotation in all turning modes assuring that patients do not “bottom out” on a hard bed surface. The mattress will maintain the patient on an air flotation surface during a power failure. When power is restored, the system will resume operation without intervention by the care giver.

Get all 3 therapy modes:
Lateral Rotation mattress provides subtle, gentle turning. Additional therapies include Alternating Pressure and on-demand Low Air Loss.

Programmable Rotation:
The microAir Lateral Rotation Mattress is capable of turning/rotating the patient up to 30 degrees. The pump system is programmable so you can set or change rotation intervals. This eliminates caregivers having to manually re-position the patient through the day or night.

Best for Prevention and Treatment:
The microAIR Lateral Rotation Mattress combines the benefits of Lateral Rotation, Low Air Loss and on-demand Low Air Loss pressure relief in a single portable system. The system's two selectable turning angles provide the ability to bilaterally rotate patients a partial turn. This reduces the risk of complications associated with immobilization. In addition, the MA90Z offers unmatched patient comfort and pressure ulcer management by regulating heat and moisture, relieving pressure and reducing friction and shear. The process is automatic and completely adjustable.

Easy-to-use control panel:
The user-friendly control panel allows the system to be customized to meet individual needs. New features like quick CPR deflate, panel lockout, low pressure alarm, and 24-hour backup help improve patient care. As with all microAIR products, the MA90Z is easy to install on a standard hospital bed and simple to operate and maintain. In fact, the microAIR Lateral Rotation Mattress by Invacare benefits everyone. It enhances patient care quality and increases caregiver productivity, all at an economical cost.

About Automatic Wireless Mode:
When the bed articulates to 30°, the transmitter in the head of the mattress signals the control unit to increase the pressure in the mattress by 80% to prevent the patient from bottoming out.

Lateral Rotation & Head Elevation:
The MA95Z will rotate the patient with the head elevated up to 40 degrees (or until the Fowler adjustment kicks in).

Price is for Mattress only, does not include hospital bed.

Input Voltage:
The MA90Z runs on 110V, 60Hz, standard U.S. voltage and draws about 2 Amps. If you need to run off 220V you will need a power converter. Any power converter used should be capable of supplying 110V, 60Hz., 200 Watts. ($10-$50 online).
example: see LiteFuze 500 Voltage Transformer

Bed Rails:

The MA90Z series mattress (including bariatric) is recommended to be installed on medical bed frames with bed side or assist rails. It is preferred that the rails be in the raised position whenever a patient is on the bed. Health care professionals assigned to each case should make the final determination whether side or assist rails are warranted after assessing patient risks of entrapment and falls.
