This study, published in the Journal of Physiotherapy, questioned whether Inspiratory Muscle Training (IMT) improves inspiratory muscle strength in adults receiving mechanical ventilation. It also asks if it improves the duration or success of weaning; if it affects the length of stay, reintubation, tracheostomy, survival, or the need for post-extubation non-invasive ventilation; if it’s tolerable; and whether it causes adverse events.
The intervention used was Inspiratory Muscle Training (IMT) versus sham or no IMT.
The study revealed that “Inspiratory muscle training improves weaning success, with potential reductions in length of stay and the duration of non-invasive ventilatory support after extubation. Patients who are having difficulty weaning may particularly benefit from the training, especially in weaning success and the duration of mechanical ventilation.”
