14
What are 4 types of chronic wounds
1. Pressure sores
2. Arterial insufficiency ulcers
3. Venous insufficiency ulcers
4. Diabetic ulcers
15
What is a pressure sore

1. Sacrum
2. Heels
3. Ischial tuberosity
4. Greater trochanter
5. Malloeli
17
What causes a pressure sore
Compression of tissues reduces blood perfusion in tissues and produces necrosis

Full thickness skin loss including damage to subcutaneous tissue
22
What is a stage IV pressure sore
Full thickness skin loss with destruction or damage to muscle, bone, or support structures
23

What causes arterial insufficiency ulcers (3)
1. Arteriosclerosis
2. Arterial occlusion
3. Arterial disruption
26
What is a venous insufficiency ulcer
Area of local blood loss due to deficiency in venous drainage
