Explain the formation of decubitus ulcers

FORMATION OF DECUBITUS ULCER:

Decubitus Ulcer, also termed as Bed sores often occur when the pressure of one’s body weight cuts off the blood supply to that organ where the pressure is applied leading to death of tissues.

It is most common among the patients who are bed ridden and among the people who sits or sleeps for a majority amount of time. When an individual is seated or is sleeping for a long time, the body exerts a pressure at the point of contact that is in between the body and the firm surface, like bed or a wheelchair. This would lead to cut off of blood supply to the point where the pressure is applied which would lead to damage of skin and tissues eventually leading to the death of tissues.
