Changes in gastrointestinal function in critically ill patients hold crucial indicative significance in the assessment of the overall disease treatment and prognosis. Bowel sounds, as an important non-invasive clinical means for monitoring gastrointestinal functional changes, currently mainly rely on auscultation, which suffers from drawbacks such as strong subjectivity, low precision, and poor scientific rigor, thereby limiting the effective clinical application of bowel sound monitoring. Therefore, this project aims to develop a multi-parameter fusion gastrointestinal function monitoring system for critically ill patients based on bowel sounds. This system enables the objective and accurate acquisition of bowel sounds. Meanwhile, by integrating vital sign parameters such as heart rate, pulse, respiration, peripheral perfusion based on pulse, and blood pressure, it establishes alarm thresholds and ranges for the overall direction of gastrointestinal functional changes. The system is characterized by continuous monitoring, non-invasiveness, portability, and low cost. It assists clinicians in enhancing the accuracy of predicting the direction of gastrointestinal functional changes in critically ill patients, providing a reliable basis for continuous dynamic monitoring and early intervention in clinical settings.
