Summary

This study looked at how a low dose of ketamine, a medicine often used for anesthesia, affects breathing and brain activity in 15 critically ill patients who were on breathing machines (ventilators) in the ICU. The goal was to see if ketamine could help stimulate breathing and improve airway function. The results help doctors understand how ketamine might be used to support breathing in these patients.
