Successful weaning is when spontaneous breathing is sustained for more than 48 hours after extubation. Despite a plethora of individual and composite weaning indices being available, most indices have not found much clinical utility, and weaning continues to be largely based on clinical assessment. Heart rate, acidosis, consciousness, oxygenation, and respiratory rate (HACOR) is a new score for prediction of failure of noninvasive ventilation (NIV) in hypoxemic patients receiving NIV. The present study explores its utilization in weaning from invasive ventilation.
