IIssoolliibbrriiuumm®, Stryker Model 2971/2972, 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.
IInntteennddeedd uussee
The IIssoolliibbrriiuumm support surface assists in the prevention and treatment of all pressure injury stages (including stages 1, 2,
3, 4, Unstageable and Deep Tissue Pressure Injury). Before implementing IIssoolliibbrriiuumm, a healthcare professional should
complete a clinical evaluation of risk factors and skin assessments. The IIssoolliibbrriiuumm patient-specific immersion to assist in
managing microclimate of the patient skin, patient repositioning, early mobility, and the prevention of pulmonary
complications.
The IInnTToouucchh and IIssoolliibbrriiuumm system is for use by patients in an acute care setting. The acute care settings may include
critical care, step down, progressive care, medical / surgical, sub-acute care, and post anesthesia care unit (PACU), or
other locations as prescribed. The patient, accessories, and any extra loading must not exceed the safe working load of
IInnTToouucchh or IIssoolliibbrriiuumm.
The operators for the system are healthcare professionals (nurses, nurse aids, and doctors) who can use all system
operations (for example: bed motion functions, nurse call, siderail communications, bed exit, or therapy options). Patients
and bystanders can use the bed motion functions, nurse call, and siderail communications but are restricted from the use of
the powered support surface functions. Trained professionals install, service, and calibrate the IInnTToouucchh and IIssoolliibbrriiuumm
system.
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.

• for use with patients that weigh less than 50 pounds
• for use with a full oxygen tent
• to support more than one individual at a time
• for use with a patient less than two years old
• in a home healthcare environment
• as a sterile product
• for use in the presence of flammable anesthetic mixture with air rich in oxygen or nitrous oxide
NNoottee -- When IIssoolliibbrriiuumm is on the IInnTToouucchh bed, a half-oxygen tent within the sidreails is allowable. Do not enclose any
part of the support surface foot box with the half-oxygen tent.
IIssoolliibbrriiuumm is not intended for use on patients with the following:
• unstable fractures
• unstable spinal cord injuries
