Also known as Adult Respiratory Distress Syndrome is a life threatening lung condition in which fluid accumulates in the lung leading to low levels of oxygen in the blood.
When a healthy person breathes, air will enter the nose and mouth passing through the trachea (windpipe) to reach the alveoli (air sacs) of the lungs. Oxygen will pass from the alveoli to small blood vessels surrounding the alveoli called the capillaries and from the capillaries to the bloodstream where it will be carried to different parts of the body. When the lung is injured from many causes including severe burns fluid and blood will leak from the capillaries into the alveoli, this will prevent air from entering the alveoli leading to decreased oxygen in the bloodstream and in turn decrease the oxygen supply to different organs which will affect their function. The lungs become inflamed, the inflammation will lead to scaring and fibrosis of the lungs causing the lungs to become stiff. This stiffness of the lung with fluid will make breathing very difficult for the patient.
