Ards occurs when fluid fills up the air sacs in your lungs. Too much fluid in your lungs can lower the amount of oxygen or increase the amount of carbon dioxide in your bloodstream. ARDS can prevent your organs from getting the oxygen they need to function, and it caneventually cause organ failure.
