Fish breathing is medical slang for a sign of acute respiratory distress when a person gulps in air through his mouth in an attempt to breathe. It's so called because the opening and closing of the mouth resembles a fish periodically sucking in water. It usually means that something in the respiratory tract or the heart has gone horribly wrong (i.e. gunshot wound, multiple organ failure, pneumonia).
