The mattress is intended for the prevention of bedsores and the treatment of stage 1-2 bedsores. The mattress consists of 16 roller-shaped chambers in which air circulates in a variable cycle. Air circulating in the mattress gently stimulates the surface of the skin, thereby promoting better blood circulation in areas of increased danger. The mattress has a quick-release (CPR) function and micro-ventilation holes that prevent moisture from accumulating in the mattress-skin contact area. Comes with an air compressor and fluid-tight cover. The air pressure is adjustable. 30–60 mmHg, cycle duration – 10 minutes. The compressor can be set in two working modes – static (when the same air pressure is constantly maintained in all chambers) or dynamic (the air pressure is changed in cycles – some chambers are full, others are empty).
