Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of pressure and flow triggering systems during continuous positive airway pressure.
Compare the inspiratory work of breathing (WOBI) during pressure triggering (PT), and flow triggering (FT) using two microprocessor ventilators. ⋯ FT reduces the WOB compared with PT, regardless of the ventilator used. The reduction in WOB during FT is related to improved responsiveness and changes in the posttrigger phase.
