decompression

The reduction of atmospheric pressure. Particularly, various techniques for preventing decompression sickness (also called caisson disease by gradual decompression. Decompression sickness is caused by the evolution of nitrogen bubbles in the body as a result of the effects of reduced atmospheric pressure. Normal symptoms of decompression sickness are the bends, chokes, and creeps; unconsciousness; and neurological symptoms. It can be potentially fatal if the original higher pressure is not restored. Fighter crews use pressure suits and pressure breathing to avoid the effects of decompression sickness. A sudden decrease in cabin pressure, which may be the result of either some component of the aircraft—such as doors, windows, or the cockpit canopy—giving way or a rupture taking place in the structure, is called explosive decompression. See also chokes and creeps.

decompression

The restoration of compressed data back to their original size. See data compression.

Although abdominal decompression is commonly referred to as an 'open abdomen', the term 'temporary abdominal closure' is less dramatic and a more accurate description thereof.
These were not patients who had abdominal decompression for IAH and ACS.
In our experience when the etiology of the IAH and ACS is aggressive fluid resuscitation for shock syndromes and significant ascites is evidenced, percutaneous abdominal decompression is an effective and safe alternative of treatment.
