Asynchronies during mechanical ventilation are associated with mortality.

Purpose: This study aimed to assess the prevalence and time course of asynchronies during mechanical ventilation (MV).

Methods: Prospective, noninterventional observational study of 50 patients admitted to intensive care unit (ICU) beds equipped with Better Care™ software throughout MV. The software distinguished ventilatory modes and detected ineffective inspiratory efforts during expiration (IEE), double-triggering, aborted inspirations, and short and prolonged cycling to compute the asynchrony index (AI) for each hour.
