Aquari Immersion Simulation System

Aquari Immersion Simulation System

Aquari Immersion Simulation is a support surface system that engages surgical patients in an immersive and 3-dimensional manner to maintain tissue symmetry, perfusion and minimize pressure injury risk.

Real-time analysis precisely adjusts the surface

Aquari analyzes the pressure waveform generated by the patient when sinking into the surface, then precisely adjusts the air density in the pad to simulate immersion in a fluid medium. 

As a result, the Aquari technology not only delivers better outcomes* for patients undergoing surgery but also addresses broader challenges associated with pressure injuries such as readmission rates and extended length of stay.**

•  Normalizes tissue symmetry and perfusion
•  3-dimensional envelopment
•  Proven clinical pressure injury reduction

Delivering Better Outcomes

Perioperative pressure injury prevalence rates for certain high risk surgery such as orthopedics are as high as an astonishing 55%. The true cost of a pressure injury is measured in patient suffering, litigation, increased length of hospital stay and the associated cost.

The Aquari is a successful approach because it is based on a simple notion: Rather than the body being forced to conform to a surface, the surface conforms to the body.

How It Works

Aquari dynamically changes the molecular density of the air in the surface in response to patient load. This creates true 3-dimensional envelopment to maintain blood flow and tissue perfusion by evenly redistributing pressure. The result? Minimize high pressure points, reducing tissue deformation and contribute to pressure injury reduction.


Aquari may be used for any surgical procedure performed on a general surgical table. Best suited for long procedures and for patients at risk for pressure injuries.

Surface Conforms To The Body

Surface Conforms To The Body

Aquari combination of immersion and envelopment benefits the patient by:

•  Minimizing vascular occlusion, maintaining near normal blood flow
•  Decreasing tissue ischemia
•  Reducing soft tissue distortion from pressure and shear
•  Maintaining near normal tissue symmetry
•  Compatible with most positioning and warming devices
•  Improving patient comfort
