Introduction
This manual is designed to assist with the operation and maintenance of the Stryker IsoAir™ System (“IsoAir™”).
Carefully read this entire manual before using or beginning maintenance on the Pump or Support Surface. To ensure
safe operation of this equipment, it is recommended that methods and procedures are established for educating and
training staff on the safe operation of the Pump and Support Surface.
INTENDED USE OF THE PRODUCT
The IsoAir™ is a therapeutic support system used to assist in the prevention and treatment of all categories/stages of
pressure ulcers (including stages I, II, III, IV, Un-stageable, and Deep Tissue Injury).
This system is intended for use in acute care and long-term care, including the home environment.
CONTRAINDICATIONS
The IsoAir™ System is intended for use as prescribed by a licensed physician. The IsoAir™ System is contraindicated
for use with certain medical conditions and treatments. Always consult with the patient’s physician before commencing
therapy with the IsoAir™ System.
PRODUCT DESCRIPTION
The IsoAir™ System offers Alternating Low Pressure (ALP) and Moisture Management (MM) on demand. The system
consists of a main control unit (Pump), which provides a pressure source for inflating and deflating the air cells in the
support surface. The support surface consists of a series of air cells that run laterally across the surface to support the
patient, and side bolsters.
The AST feature is an auto-sensing function that is used to provide optimal immersion.
PRODUCT & THERAPY OVERVIEW
The IsoAir™ helps to prevent and treat pressure ulcers. The air cells in the support surface are positioned every 4
inches (10 cm) from the head to the foot. Two types of therapy are available, Pressure Redistribution and
ALP. Pressure Redistribution therapy fills the cells with just enough air to deeply immerse the patient into the surface.
This immersion distributes pressure to support the patient as evenly as possible. ALP therapy will alternately inflate
and deflate every other cell to relieve pressure and allow blood to flow into the tissue more easily. This function will
continue to cycle every 6 minutes.
An additional feature called Moisture Management (MM) is available. MM enhances patient comfort and helps to
prevent and treat pressure ulcers by removing moisture through the top cover. Air is pumped into the surface in the
seat and torso areas to evaporate the moisture.
The Pump is connected to the air cells through flexible hoses. The Pump monitors and adjusts the air in the air cells
automatically. If less air is required then the Pump opens a valve to vent some out. If more air is required then the
Pump turns on its air compressor and opens a valve to direct more air into the cell.
There are two ways that the firmness / softness of the surface can be set. Manual mode allows the user to select one
of five preset levels. AST mode utilizes sensors in the seat area of the surface. These sensors determine the amount
of immersion of the patient. If the mattress is too soft and the patient is immersed too much, the Pump will increase the
air pressure in the surface. Conversely, if it is too hard the Pump will decrease the air pressure in the surface.
ISOAIR™SYSTEM COMPONENTS
The IsoAir™System is composed of a Support Surface (Mattress) and a Pump. The Surface has a built in Hose
Assembly that connects to the Pump via the CPR Connector.
The Pump is supplied with two power cords, a long cord and a short cord. The long cord is for wall connection and the
short cord is for connecting directly to the power socket built into some Stryker bedframes.
The system is accompanied by an Operation/Maintenance Manual.

while this mode is active). The cells will remain inflated to maximum pressure for 15 minutes. A countdown timer is
displayed on the display, indicating the time remaining in Max Inflate override mode. An alert tone is emitted when
the Max Inflate override mode times out.
While the Max Inflate override mode is active, activating either main therapy mode (via the ALP or PRESSURE
REDISTRIBUTION Keys) will disable Max Inflate override mode.
Pressing the AST key does not affect the MAX Inflate operation.
After Max Inflate override mode times out or is disabled, the Pump resumes operation based on the therapy mode
setting and pressure settings in effect prior to initiating the Max Inflate Override mode.
PRESSURE REDISTRIBUTION (STATIC) FUNCTION
Pressing the Pressure Redistribution Key activates the Pressure Redistribution therapy mode, which keeps all cells
at constant pressure and allows for manual adjustment of cell pressure (PRESSURE UP and PRESSURE DOWN
Keys will function normally while this mode is active). Activating MAX INFLATE or ALP mode (via their respective
Keys) will disable Pressure Redistribution therapy mode.
