Pathophysiology病理学
Soft tissue pressed
between bony prominence
and external surface for a
prolonged period of time.
软组织长期受压于骨骼隆突与外部硬面之间
1. Unrelieved pressure
未被释放的压力
2. press
血管受压
3. Can’t deliver Oxygen and
Nutrition
无法输送氧气和营养
4. Ulcer forms
形成溃疡

Common Sites易发部位
mon常见: yx尾部, Sacrum骶骨部, Heels足跟部
Reason病因:
less soft tissue is present between the bone and skin
这些部位的骨骼和皮肤间的软组织较少

Capillary Pressure毛细血管压
Normal Pressures正常值:
Arterial Capillary
动脉毛细血管压: 30-40mmHg
Mid Capillary
中间毛细血管压: 25mmHg
Venous Capillar:
静脉毛细血管压: 10-14mmHg
Need 17mmHg to Function;
需17mmHg才能活动;
Capillary Closing Pressure
毛细血管闭合压: 17-32mmHg
