Sternomastoid, Rib Cage, and Expiratory Muscle Activity During Weaning Failure.
Predicting if a patient will be able to wean from mechanical ventilation is an important part of critical care medicine. Previous observations have been made that the use of inspiratory and expiratory muscles may differ for those who fail weaning compared to those who successfully resume independent breathing. In this study, the authors have demonstrated via EMG analysis that the timing and pattern of ventilatory muscle use may be able to predict failure to wean. Since physical therapists are highly trained to observe and manipulate motor patterns, including those of ventilation, they may be able to give critical input to the health care team regarding ability of a patient to breathe independently. Likewise, interventions aimed at altering dysfunctional motor patterns of ventilation may lead to improvements in ventilator weaning.
