What is pressure injury?

Pressure injury can affect people who spend a long time in one position, for example, because of paralysis, illness, old age, or frailty.

Also known as pressure ulcers and bedsore, pressure injury can happen when there is friction or unrelieved pressure on one part of the body. The sores can affect any part of the body, but the bony areas around the elbows, knees, heels, coccyx, and ankles are more susceptible. Bedsores are treatable, but, if treatment comes too late, they can lead to fatal complications.

The area may be very red and inflamed. The wound may be foul-smelling like rotting flesh, and bleed with weep fluid(Picture ①~④)
