Final answer:
Skin breakdown or pressure injuries can be caused by excessive pressure, injuries to the skin, and infections. It is important to prevent and treat these conditions to maintain skin integrity.
Step-by-step explanation:
Skin breakdown or pressure injuries can be caused by various factors. One common cause is excessive pressure or friction on the skin, which can lead to the formation of bedsores or decubitis ulcers. Bedsores occur when constant, long-term pressure is applied to certain bony body parts, reducing blood flow and causing tissue death.
In addition, injuries to the skin, such as burns, wounds, and scars, can also contribute to skin breakdown. These injuries can result from sharp objects, heat, or excessive pressure on the skin. Furthermore, infection can occur when the skin's physical barrier is damaged, allowing microbes to enter deeper tissues and causing wound infections.
In summary, skin breakdown or pressure injuries can be caused by excessive pressure, injuries to the skin, and infections. It is important to prevent and treat these conditions to maintain skin integrity.
