Clinical Management of Intra-Abdominal Hypertension via Pressure Measurement Devices
Intra-abdominal pressure (IAP) is the steady-state pressure concealed within the abdominal cavity. In critically ill patients, monitoring this pressure is vital to prevent Abdominal Compartment Syndrome (ACS), which occurs when elevated IAP leads to multi-organ dysfunction.
Measurement Methodology and Pathophysiology
The most common method for measuring IAP is the trans-bladder technique, utilizing a specialized pressure transducer system.
Procedure: A small volume of sterile saline (usually 20–25 mL) is injected into the bladder through a Foley catheter. The catheter is then clamped, and the pressure of the fluid column is measured at the end of expiration.
Grading Hypertension: * Grade I: 12–15 mmHg
