Emerg was designed to reduce the risk of therapy errors and automatically sense and adjust the pressure environment specific to the patient’s needs without additional adjustments. Emerg mimics a fluid medium and provides greater immersion into the surface while enveloping the bony prominence. Immersion into a surface increases the contact area between the body and the therapy surface resulting in lower pressures. Optimizing pressure redistribution will result in reduced soft tissue distortion, friction, and shear vs shearing.
