Intra abdominal pressure monitoring

Foley
Pressure transducer zeroed at level of symphisis and inserted into aspiration port of IDC
Clamp catheter
Instil 50-100mL of saline
Can measure indirectly by placing U shaped loop in Foley with apex of loop at level of symphisis (10mmHg = 13.6cm H20)

Abdominal compartment syndrome occurs in a graded manner
Anuria is usuallt present by 30mmHg

30cm H20 (22mmHg) is a critical level requiring therapy used by some
Clinical judgment is required
Sequentially rising measurements in the face of pulmonary, renal and cardiovascular compromise may necessitate decompressive laparostomy
