Both IMV and PSV can be used during the weaning process. It is important to note that regardless of which technique one uses, the rate at which the level of ventilatory support is reduced is usually determined by the patient's lung disease and the resolution of loads that the disease has imposed. Nevertheless, there are substantial differences between the IMV and the pressure-support approach to weaning that may affect patient comfort, synchrony, muscle reconditioning, and thus perhaps the ease with which a patient is weaned. Understanding these differences will allow reasonable application of PSV today and will guide future research on the relationships between mechanical ventilatory support and ventilatory muscle function.
