Nasoenteric Tube Placement Success Predictor

The calculator is based on a logistic regression model derived from a retrospective cohort of 287 ICU patients. It incorporates eight clinical and anatomical predictors, including the angle between the gastric greater curvature and the pylorus, the vertical distance from the lowest tube point to the iliac crest, insertion depth, procedure duration, SOFA score, and operator competency level.

The tool is designed for pre-procedural risk stratification to guide the selection of blind versus image-guided placement. The code is provided as a standalone HTML file and can be run locally in any modern web browser without server dependencies.
