Key features

  • An Automatt sensor pad, below the entire length of the mattress, works with the automatic pump, constantly readjusting cell pressure to keep the interface pressure below 10 mmHg for up to 40% of the operating cycle.
  • Five heel cells incorporate vent valve technology, allowing the caregiver to fully remove interface pressure from this high risk area, and providing zero pressure for the most vulnerable patients, such as those with limb ischemia or existing wounds.
  • The mattress can be transformed from a powered support surface into a sealed static air mattress for up to 12 hours, providing a uniform stable surface for patient transportation, nursing procedures, moving & handling and providing basic support in the event of a power failure.
  • Cardio Pulmonary Resuscitation (CPR) and Rapid Air Deflate Release (RADR) is a quick release, single-handed function located on the mattress control unit that enables rapid air deflation for emergencies, short-term physiotherapy, patient transfers and handling or storage.
