True³ Digital TRI-PHASIC Technology
Most current support surfaces (Low Air Loss, Air Fluidized) are immersion technologies – pressure reduction through body mass distribution. True³ Digital Systems are based on TRI-PHASIC, Multiple Cell Alternating Technology – True Offloading by Sequential Pressure Relief. It is Important to know the differences in these technologies to effectively evaluate these systems.
TRI-PHASIC, Multiple Cell Alternating Technology
The True³ Digital Mattress System does not function by “immersion” for standard body mass distribution of pressure. Instead, pressure alternates cyclically through a series of 3-cell groupings throughout the mattress system. The True³ Digital System TRI-PHASIC Technology employs a 3-Cell alternating cycle (A – Peak Pressure, B – Midlevel Pressure, and C – Minimum to Zero Pressure) which automatically changes the pressure in the cells every 2.5 minutes. This TRI-PHASIC Alternation ensures that one-third of the body has pressure relief every 2.5 minutes (full body pressure relief every 7.5 minutes).
Cyclical pressure alternation helps to prevent prolonged, damaging capillary occlusion and to stimulate the flow of blood (reactive hyperemia) and lymphatic fluids to provide oxygen and remove waste.
TRI-PHASIC pressure alternation provides the Support and the Offloading that allows the patient to be placed “on the system” instead of “in the system”. True³ systems support the patient normally so that the neck, spine, and pelvis can remain in a more natural position. This relieves the back, hip, and neck pain that can result from skeletal misalignment in patients lying down within “immersion” systems.
“Reactive” versus “Active” Support Surface
Most of the current support surface technologies are immersion technologies (sinking a patient into a surface) based on pressure reduction through body mass distribution (“Reactive”). True³ Digital Mattress Systems employ TRI-PHASIC Alternating Pressure technology based on true offloading through sequential, cyclical pressure relief (“Active”). It is Important to know the differences in these classifications to effectively evaluate the systems.
“REACTIVE” SUPPORT SURFACE
“ACTIVE” SUPPORT SURFACE
Industry Experts & the NPUAP classify support surfaces as “Reactive” or “Active”.
“Reactive” systems are defined as those systems (powered or unpowered) that are designed to increase the area of the body in contact with the surface by immersion. The patient sinks into the mattress like in a hammock. This often creates neck, hip and back pain (because of the unnatural curvature of the spine and pelvis) causing the patient to be uncomfortable. This discomfort can result in lowered patient compliance and may even require pain medication to manage. Pressure is redistributed for pressure reduction, but PRESSURE is CONSTANT unless the patient is moved. PRESSURE is NEVER reduced to zero.
“Active” systems are defined as those systems (always powered) that are designed to make periodical changes in pressure regardless of patient movement. In addition to pressure reduction, these cyclical pressure changes provide True Offloading through sequential pressure relief.
True³ Digital Mattress Systems are designed on the “Active” model. They provide cyclical, sequential changes in pressure to the patient’s skin by employing TRI-PHASIC Alternating Technology to automatically change the patient interface pressures every 2.5 minutes. One-third of the body experiences pressure relief every 2.5 minutes (the entire body experiences pressure relief every 7.5 minutes). This cycle allows for the body to be sequentially offloaded 8 times per hour. PRESSURE is NOT CONSTANT. PRESSURE is sequentially REDUCED to ZERO.
Defining Active Pressure Redistribution
“As each patient presents with a unique and changing risk profile, it is not possible to determine a universally ‘safe’ pressure-duration threshold for each individual. A principal design goal is, therefore, to mimic the protective effect of repositioning by periodically reducing contact with the support surface to a level that is as low as practically achievable for as long as possible. Off -loading cycles ideally occur several times each hour to reduce the risk of ischemia reperfusion injury; a condition associated with vessel occlusion (closure or blockage) for as little as one to two hours.”
“Active surfaces, by the very nature of their design, periodically off-load the tissue, meaning that they are considered the modality of choice for patients who cannot be regularly repositioned. Examples might be end-of-life care, intensive care, long-term care where reduced sleep interruption is preferred, or simply patient choice.”
What Can True³ Digital Systems Do for You?
