Abstract
An abdominal decompression apparatus is used to treat a variety of disorders including acute abdominal compartment syndrome, increased intra-abdominal pressure related morbidity in severely obese persons, and pre-eclampsia and other complications associated with increased abdominal pressure in pregnancy. The abdominal decompression apparatus is worn for an extended period of time (e.g., 6-12 hours at a time), with relatively low levels of pressure being applied (e.g., -20 to -45 mm Hg). Preferably, abdominal decompression is performed on a continuous basis with the final pressure being gradually achieved. In a preferred embodiment, the patient's urinary bladder pressure is used as a measure of intra-abdominal pressure. The sensed urinary bladder pressure can be used to gauge the effectiveness of treatment as well as to control parameters of the abdominal decompression device (e.g., time of use, pressure utilized, etc.).
