Summary

This study looks at whether a fast, automatic eye test can predict delirium (sudden confusion) in intensive care patients who need a breathing machine. Delirium is common and serious, but current screening methods take time and training. Researchers will measure pupil reactions in 213 adults on day 3 of ventilation and see if those results can forecast delirium over the next two weeks. The goal is to make detection easier and faster.
