Clinical Mechanism
Engineered against the four dimensions
Interface pressure over time — AERIS stays below the 32 mmHg threshold.
→ Mechanics
TX 13.5–32 mmHgSustained pressure above the capillary closing pressure (~32 mmHg) restricts perfusion. AERIS TX reduces interface pressure to 13.5–32 mmHg and redistributes load zone by zone — the HC line targets a 30–60 mmHg comfort / anti-pressure range.
→ Time
0–30° · 15–120 minTissue offloaded for > 2 hours carries ischemic risk. Automatic 0–30° rotation returns pressure toward zero on a cycle, supporting reperfusion without manual handling.
→ Perfusion
p = 0.04 O₂ · p = 0.001 flowAlternating-pressure sequences have been shown to increase tissue oxygen saturation (p = 0.04) and skin blood flow (p = 0.001).
→ Microclimate
25–40°C · 0.3 m/minMoisture and heat promote injury. 25–40°C airflow at 0.3 m/min with high-absorbency linen helps keep skin dry, supporting the barrier against incontinence-associated dermatitis.
