Final answer:
Pressure ulcers, also known as bedsores or decubitis ulcers, are caused by constant and unrelieved pressure on the skin and underlying tissues. These ulcers can be prevented by relieving pressure and practicing good skincare.
Step-by-step explanation:
Pressure ulcers, also known as bedsores or decubitis ulcers, are caused by constant and unrelieved pressure on the skin and underlying tissues. This pressure reduces blood flow to the area, resulting in tissue damage and necrosis. Bedsores are most commonly seen in elderly individuals who are immobile or have debilitating conditions.
For example, if a patient is confined to a bed or wheelchair and not repositioned regularly, the pressure on their skin can lead to the development of bedsores. These ulcers usually occur on bony areas of the body, such as the hips, heels, tailbone, or elbows. If left untreated, the ulcers can become infected and potentially life-threatening.
To prevent pressure ulcers, it is important to relieve the pressure by repositioning regularly, using supportive devices like cushions or mattresses, and practicing good skincare.
