Amico’s Powered Therapeutic Mattresses play an important role in your decision for ulcer prevention. With the option of air-filled, low-air-loss and alternating air mattresses, pressure relief can be achieved with the use of technology to create dynamic surfaces. Pressure ulcers result from prolonged pressure that cuts off the blood supply to the skin, causing the skin and other tissue to die. The damage may occur in as little as 12 hours and may go unnoticed until the skin begins to break down, days later.
