What is intra abdominal pressure?

Intra-abdominal pressure (IAP) refers to the pressure within the abdominal cavity, which is influenced by various factors such as body position, respiratory activity, and the presence of intra-abdominal organs and fluids. It plays a crucial role in maintaining core stability, facilitating organ function, and supporting venous return to the heart. Elevated IAP can lead to conditions such as abdominal compartment syndrome, which can impair organ function and overall health. Monitoring IAP is particularly important in critically ill patients and those undergoing major abdominal surgery.
