The Invacare MicroAIR Alternating Pressure Mattress Systems are a powered alternating pressure mattress replacement designed to aid in the prevention and treatment of pressure ulcers (bed sores). The MA65 reduces interface pressure by alternately inflating and deflating 20 individual 8-inch air cell bladders every 5, 10, 15 or 20 minutes. 

Patients with immobility or perceptual problems who remain bedridden for extended periods can develop open sores at points where the weight of the body compresses the skin, often under bony prominences like the hips or shoulders. These sores are called pressure ulcers. 

The alternating pressure mattress replacement system helps in pressure ulcer treatment and management by shifting pressure to different parts of the body in a repeating cycle, which prevents any body area from being under pressure all the time.
