INTRODUCTION
Pressure injuries are dened as localized injuries of the skin and/or underlying tissue over a bony
prominence as a result of pressure or pressure in combination with shear. Support surfaces or specialized
mattress systems are used as part of an overall, multi-disciplinary, multi-dimensional care plan intended to
prevent and treat pressure injuries.
The Harmony support surface is a high quality, tri-therapy active blower system that combines true low air
loss and dynamic alternating pressure. Specically designed for the prevention and treatment of pressure
injuries, while optimizing patient comfort.
Indications for Use
Effective pressure redistribution therapy, wound management and device selection should be based on
the patient’s specic clinical condition and complete assessment of needs, recognizing that pressure
prevention devices are only one component of a comprehensive pressure injury management program.
Support surfaces are not substitutes for turning, repositioning or functional weight shifts by caregivers.
The Harmony, Tri-Therapy Mattress Replacement System is intended for:
1) Pressure redistribution for individuals with but not limited to the following conditions:
2) Shear & Friction Reduction:
Friction is dened as the resistance of motion in a parallel direction relative to the common boundary of two
surfaces. For patients this can occur when the skin rubs against another surface.
Shear (or shear stress) is the force per unit area exerted parallel to the perpendicular plane of interest.
Shear strain occurs when skin is distorted or deformed as a result of shear stress.
3) Spinal Cord Injury:
The Harmony system can be used for patients with spinal cord injury once the acute injury has been
stabilized and these patients have been assessed and cleared by the appropriate clinician.
These instructions and recommendations are in accordance with the 2019 Clinical Practice Guidelines of
the National Pressure Injury Advisory Panel (NPIAP), the European Pressure Ulcer Advisory Panel (EPUAP)
and the Pan Pacic Pressure Injury Alliance (PPPIA).
Contraindications
Patient conditions for which the application of pressure relieving therapy on a true low air loss, blower-
based system is contraindicated are as follows:
1) Unstable spinal cord injuries
• At risk for or present pressure injuries
• Neurological conditions
• Amputations
• Grafts
• Burns
• Dermatological conditions
• Flaps
• Rehabilitation needs
• Pain management as prescribed by a
physician.

14
General Repositioning
Patients should be turned or repositioned based on their individually planned treatment schedule or per
facility policy. Support surfaces are not substitutes for turning/repositioning or functional weight shifts.
Hand Check Procedure:
A suitable way to verify that the patient is not bottoming out is to perform a hand check as described below:
1) Ensure that the patient is lying supine (on his/her back) in the middle of the mattress.
2) Place a hand with four (4) ngers stacked vertically beneath the air cell directly underneath the sacral region.
3) Ensure that the 4 ngers can slide with minimal resistance between the patients’ sacral region and the
lower portion of the mattress.
4) Adjust the comfort setting as needs.
5) Wait for the mattress to adjust to the selected range.
6) Revaluate with the hand check and adjust to patients’ comfort level.
Recommended Linen:
Drive DeVilbiss Healthcare bed support surfaces are designed to be used with appropriate linens. Deep
pocketed tted or at sheets are recommended. Multiple layering of linens or underpads beneath the
patient should be avoided, when possible, for the prevention and treatment of pressure injuries.
Incontinence
Moisture against the skin surface is an extrinsic risk factor for acquiring a pressure injury as it weakens
the skin tissue leading to maceration. To protect skin integrity, incontinence barrier pads may be used to
absorb excess moisture.
Warning
Specialty active and reactive support surfaces are designed to redistribute pressure and reduce shearing/
friction forces against the patients’skin. Patient migration is possible due to the nature of these products.
Always ensure the patient is positioned properly within the connes of the bed and specialty system.
