Method and system of measuring the intra-abdominal pressure of a patient

摘要

A method and apparatus for measuring the intra-abdominal pressure (IAP) within a patient having a naso-enteric tube. The system senses the IAP of the patient by means of a fluid filled sensing conduit that transmits the pressure in the naso- enteric tube to a pressure measuring device such as a pressure transducer or a manometer tube. The sensing fluid in the sensing conduit may be saline, air, or feeding solution. When a pressure transducer is used, the IAP is determined and displayed on a patient monitor. Alternatively, the IAP may be determined from the height of the sensing fluid within the sensing conduit.
