預防壓瘡的核心概念在於「壓力再分配（Pressure Redistribution）」。長時間的單一姿勢會導致皮膚與皮下組織缺血缺氧，進而壞死。每 2 小時更換姿勢是臨床公認最有效的預防策略，能有效分散骨突處的壓力。此外，護理師應結合營養評估、皮膚護理與使用適當的輔助減壓器材（如氣墊床）來全面性預防。
Repositioning the client every two hours is the most effective preventive measure because it redistributes pressure and restores blood flow to ischemic tissues. This standard practice mitigates the risk of pressure ulcer development by preventing prolonged compression over bony prominences.
