Pletsch-Assuncao R, et al. - Herein, researchers assessed the accuracy of criteria for diagnosing pressure overassistance during pressure support ventilation. They found that a respiratory rate of 17 breaths/min was the parameter with the greatest accuracy for diagnosing overassistance. In addition, for confirming or excluding pressure support overassistance, respiratory rates of less than or equal to 12 or greater than or equal to 30 served as useful clinical references.
