Study Notes
Pressure Ulcers
- A pressure ulcer is considered a type of wound that develops when sustained pressure on the skin restricts blood flow, leading to tissue damage and cell death.
Causes of Ulcerations
- Ulcerations can be caused by factors besides sustained pressure on the skin, including:
- Inadequate nutrition
- Friction
- Shear forces
- Moisture
- Infection
Effects of Sustained Pressure
- Sustained pressure on the skin can lead to:
- Tissue ischemia
- Cell death
- Necrosis
- Ulceration
Classification of Pressure Ulcers
- A pressure ulcer is a type of chronic wound that develops over a bony prominence.
Skin Anatomy
Epidermis Layer
- The primary function of the epidermis layer of skin is to provide a barrier against external factors, such as water loss and infection.
Skin Cancer
- Skin cancer is typically first visible on the epidermis layer of skin.
Hypodermis Layer
- The main function of the hypodermis layer of skin is to attach the skin to underlying tissues and provide thermoregulation.
Dermis Layer
- The dermis layer of skin contains:
- Blood vessels
- Nerve endings
- Hair follicles
- Sweat glands
- Sebaceous glands
