Intra-abdominal pressure (IAP) is the steady-state pressure inside brthe abdominal compartment. Based on literature, approximately more brthan half of the critically ill patients develop intra-abdominal brhypertension (IAH) within their stay in the intensive care units (ICUs). brSince perfusion pressure of the abdominal organs is a function of brIAP, elevated IAP results in diminished organ perfusion, multiple brorgan failure, and death depending on the severity of IAH. Therefore, brmonitoring IAP is necessary for patients hospitalized in the ICU. brPresently, the reference standard for IAP monitoring is an invasive brmeasurement method through the bladder. This measurement brtechnique reflects the abdominal pressure with relatively high braccuracy and reliability, however, it carries a high risk of infection and bris not applicable to patients with hematomas or other pelvic masses. brAdditionally, it is a non-continuous IAP measurement technique that brcan be used every 6 to 8 hours. Consequently, there is a huge brdemand for developing a novel non-invasive IAP measurement brmethod for critically ill patients. This project aims to design and brfabricate a microwave-based sensor on the basis of a novel radarbased technique known as transient radar method (TRM) for noninvasive IAP monitoring. In the long term, however, we aim to brdevelop a certified medical device based on this research project with bra worldwide application for intra-abdominal pressure measurement.br
