This easy-use air system is for the professional treatment and prevention of up to stage II and III decubitis. A large cell mattress system, this device has two chambers, a CPR valve, and a head section which is static. The device is controlled by a microprocessor. Optimal pressure can be provided by this machine for patients who weigh between 40 – 160 kg. Non-slip coverings and air penetration are included to offer excellent comfort. Selective pressure relief reduces the chances of hollow positioning. Low vibrations in the machine cause it to run quietly.
