The Stryker Model 2941, IIssooAAiirr® system consists of a support surface and pump. The support surface is an air powered
support surface that consists of air cells and bladders that run across the surface to support the patient and side bolsters.
The surface is outfitted with a pump that provides the pressure source to inflate and deflate the air cells. The pump,
connected to the air cells through flexible hoses, monitors and automatically adjusts the air in the air cells dependent on the
type of therapy selected. This product includes alternating pressure (ALP), low air loss (LAL), max inflate, active sensor
technology (AST), and CPR deflate. Comfort control is provided through five levels of alternating low pressure and static
pressure.
IInntteennddeedd uussee
The IIssooAAiirr system helps in the prevention and treatment of pressure injuries or pressure ulcers (all stages, Unstageable
injury and Deep Tissue injury). Stryker recommends this product to be implemented in combination with clinical evaluation
of risk factors and skin assessments made by a healthcare professional. This product provides pressure redistribution and
is intended to assist in management of the microclimate of the patient skin.
The IIssooAAiirr system is intended for use with a bed frame and a top sheet. The system is intended for use in an acute care
and long-term care units, including general hospital use, critical care, step down care, Med/Surg, PACU, and progressive
care settings.
This product is not intended for use in a home healthcare environments, with pediatric patients, or in behavioral healthcare
units. This product is not sterile.
EExxppeecctteedd sseerrvviiccee lliiffee
The IIssooAAiirr support surface has a 3 year expected service life under normal use conditions and with appropriate periodic
maintenance.
The IIssooAAiirr pump has a 5 year expected service life under normal use conditions and with appropriate periodic
maintenance.
DDiissppoossaall//rreeccyyccllee
