    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
