ARDS. A lung injury caused by many different conditions where the membrane separating the air space from the blood space becomes porous allowing fluid to fill up the air spaces and prevent o2 transport. The lung becomes stiff and difficult to inflate increasing the work of breathing. Most people will require a ventilator and ICU care.
ARDS... ...Is a problem where the small blood vessels in the lungs become leaky (capillary leak), causing the lungs to get very congested. This makes the lungs stiff and decreases the ability for oxygen to diffuse into the blood. ARDS can be caused by a variety of inflammatory process (such as infection, injury, burns, pancreatitis, etc.). ARDS can also be caused by blood transfusion or medications.
