Stryker Model 2972 IIssoolliibbrriiuumm® is a powered support surface with features that provide Pressure Redistribution, Low Air
Loss, and Lateral Rotation. IIssoolliibbrriiuumm is for use with the IInnTToouucchh® (revisions 4.0 or higher software) bed frame.
IIssoolliibbrriiuumm and IInnTToouucchh are an integrated bed and surface system that caregivers use to assist in patient care.
IInnddiiccaattiioonnss ffoorr uussee
The Stryker Model 2972 IIssoolliibbrriiuumm support surface is intended to assist in the prevention and treatment of all pressure
injury or pressure ulcers (includes all stages, unstageable and deep tissue pressure injury). As a recommendation,
healthcare professional should complete a clinical evaluation of risk factors and skin assessments. The intended users is
both healthcare HCPs (nurses, nurse aids, and medical doctors), transporters, and human patients. This product is for use
by human patients in a health delivery organization (HDO).
The IIssoolliibbrriiuumm patient-specific immersion is intended to assist in the management of microclimate of the patient’s skin,
patient repositioning, and the support in prevention of early mobility and pulmonary complications.
The IIssoolliibbrriiuumm powered support surface is not intended for use in or with:
• Oxygen rich environments
• Sterile environments
• Home care or long-term care facility settings
• Behavioral health populations
CCoonnttrraaiinnddiiccaattiioonnss
IIssoolliibbrriiuumm is contraindicated for use on patients with:
• Unstable fractures
• Unstable spinal cord injuries
EExxppeecctteedd sseerrvviiccee lliiffee
IIssoolliibbrriiuumm support surface has a five year expected service life under normal use, conditions, and with appropriate periodic
maintenance.
IIssoolliibbrriiuumm covers (top and bottom) have a two year expected service life under normal use, and conditions.

Physical Concepts Pressure Redistribution The ability of a support surface to distribute load over the
contact areas of the human body.
Pressure Redistribution setpoint Allows the operator to input patient weight range resulting
in automatic change of zoned sensor technology allowing
immersion and envelopment.
Lateral Rotation Therapy A feature of a support surface that provides rotation about
a longitudinal axis as characterized by degree of patient
turn, duration, and frequency.
BBaacckkSSmmaarrtt® Turn Assist A feature of a support surface that provides a single
position turn about a longitudinal axis.
Max Inflate Allows maximum firmness inflation for use when boosting a
patient and on lateral transfer, Promotes patient ease with
dangling, egress, and ingress.
Moisture management The top surface cover draws excess moisture away from
the patients skin and support surface interface.
Low Air Loss (LAL) Provides air flow to assist in the management of
(microclimate) the skin.
HHeeeellGGeell®1Technology A feature of the support surface to address pressure
redistribution in the heel area.
PPaattiieenntt SSppeecciiffiicc IImmmmeerrssiioonn™ Assists in managing microclimate of the patient skin,
patient repositioning, early mobility, and prevention of
pulmonary complications.
