Measurement via the drainage tubing sampling port (versus catheter) allows  The BARD® Intra-abdominal Pressure (IAP) Monitoring Device is intended for the monitoring of intra-abdominal pressure via a Foley urinary catheter. BACKGROUND: Increased intra-abdominal pressure (IAP) is an adverse complication seen in critically ill, injured, and postoperative patients. are also linked with elevated IAP [11,12,13]. The bladder is then filled with either water or an x-ray dye. Because measurement of IAP by an indwelling catheter in the urinary bladder is simple, minimally invasive, and reproducible, it has been forwarded as the gold standard. Likely primaries include malignancies of the transverse colon, gallbladder, urinary bladder, liver, and omen-tum. After emptying via the catheter, the bladder was filled with saline at 37°C, through a second 5-French urethral catheter, at a constant rate of 50 ml/min with Abdominal tap, or paracentesis, is a procedure to remove excess fluid from the abdominal cavity, which is the area between the abdominal wall and the spine. Diagnosis relies on intra-abdominal pressure (IAP) measurement, as clinical estimation and abdom-inal perimeter are poorly correlated with the actual IAP [1-5]. 9 The technique of intravesical pressure (IVP) measurement 81011 has been validated 12 and remains the body position when we use different methods to measure IAP. Although there are many risk factors for the development of IAH, in the era of goal-directed therapy for shock, brisk volume resuscitation and volume overload are the most Suprapubic catheterization via percutaneous cystostomy is done by a urologist or another experienced physician.
