(Intelligent Pressure Sensing) Technology is what separates the Primatech line surfaces from other products available in today’s market. I.P.S. Technology allows the system to deflate to zero pressure in the deflated zone and allows for accurate pressure levels in the inflated zone by monitoring the air pressure every six seconds. This controlled movement of the air cells gives the benefit of alternating pressure without the extremely high peak pressures. The result is better patient comfort, lower interface pressures, and superior results.
