Summary

This study looks at whether measuring blood flow in the stomach and intestines can help predict feeding intolerance in critically ill patients. Researchers will monitor 500 ICU patients receiving tube feeding and track symptoms like vomiting, bloating, or diarrhea. The goal is to build a prediction model that helps doctors adjust feeding plans earlier and reduce complications.
