FREE AIR
Abnormal air in the abdomen. Typically air should be seen only in the bowel ("intestine"). Air outside of bowel can be a sign of perforated ("leaky") stomach or bowel, which can be a life-threatening condition. Free air can be a normal finding after recent surgery in the abdomen.
FREE FLUID
Water within the abdomen or pelvis that sloshes around freely (i.e. not trapped in one spot). In some cases, it is a normal finding. For example, young female patients can have small amount of free fluid in the pelvis. Other times, it is abnormal. It can be from a number of different causes (both benign and cancerous).
