How Does the Dolphin FIS System Help with Wound Healing?
The FIS System measures the patient’s weight, surface area, and other characteristics to create an individualized immersion profile that prioritizes patient comfort. By eliminating gradient shear forces, this technology helps promote friction reduction, improved tissue perfusion and healing from skin grafts and pressure ulcers.
The Next Generation of Immersion Therapy
The Emerg® Auto-Emersiontherapy™ system customizes fluid-like surface immersion by automatically sensing and adjusting the pressure environment specific to the patient’s therapy needs. Speak with our representative to learn more about this advanced therapy system.

FAQS
Both Emerg® Auto-Emersiontherapy™ and the Dolphin Fluid Immersion Simulation® System are immersion mattresses that simulate a fluid medium and automatically adjust to each patients’ pressure points. However, Emerg is manufactured by Ethos, while the Dolphin FIS System was created by Joerns Healthcare. Emerg offers features like Touchscreen TEC-Nology and side bolsters for stability, while the Dolphin FIS mattress replacement is compatible with a wider range of existing bed frames.
This support surface is designed for patients with spinal cord injuries and other mobility-limiting medical conditions with high risks for pressure injuries.
The Dolphin FIS System requires battery power to operate. However, it has a 12-hour battery life, which allows for continuous therapy during power outages.
