Fluid Immersion Simulation
What is FLUID IMMERSION SIMULATIONTM (FIS)? The short answer: A technology that simulates the effects of a body "floating" in a fluid, thus alleviating vertical shear forces which deform soft tissue.

Fluid Immersion SimulationTM is a state of the art pressure redistribution technology. It incorporates concepts from physics like Boyle's Law (Air Viscosity) and the Archimedes Principal (buoyancy) into algorithms that simulate immersion in a fluid. By using a microprocessor and sophisticated dynamic pressure waveform analysis software, the system is able to analyze in a three dimensional volumetric format the anthropometric characteristics (shape) of a patient engaged on the mattress.

By providing active feedback and detection and correction for the support surface based on the mass and area in contact with the surface, the system is able to approximate immersion in a fluid medium. Consequently, the supported object is truly floating, cradled in a simulated fluid environment without experiencing soft tissue strain. CT and PET scans verify the system's ability to maintain normal tissue symmetry. FISTM has been further validated by perfusion studies that demonstrate the system's ability to maintain micro-circulation to peripheral tissue which is critical when trying to prevent or heal deep tissue injury.




Our Auto-Vector FISTM Unit offers a unique display of patient's "Immersion Profile" indicating presence of harmful shear forces and subsequent validation of corrective action taken by the micro-computer.

Figure 1.

CT scan of subject in prone position. Natural symmetry of the gluteal area, showing distances from the most posterior point of the ischial tuberosities to the skin surface as 91mm and 86mm.

Figure 2. Two-dimensional surface

CT scan of subject in the supine position on a two-dimensional surface. Subcutaneous tissue and muscle has compressed and distorted, as well as the lumen diameter of micro-circulation has been reduced, with complete loss of gluteal fold. Distances from the most posterior point of the ischial tuberosities to the skin surface are 75mm and 78mm.

Figure 3. Three-dimensional surface

CT scan of subject on the our three-dimensional Dolphin BedTM surface. Natural symmetry of the gluteal area returns and maximization of the normal lumen diameter of micro-circulation, with restoration of tissue symmetry. Distances from the most posterior point of the ischial tuberosities to the skin surface are now 109mm and 99mm.
