Brief summary
This observational study examined double triggering asynchrony in28ICU patients on mechanical ventilation. Researchers collected data on patient characteristics, health conditions, and outcomes to understand how this problem affects critically ill patients. Findings may help improve ventilator care in intensive care units.
