Neurally Adjusted Ventilatory Assist in Adults at Risk of Delayed Weaning From Mechanical Ventilation

Many patients admitted to intensive care have heart or lung problems. Patients with these conditions often require longer durations of support from breathing machines. Survival and long-term recovery are improved if the investigators can remove the breathing support quickly. In this study, the investigators will focus on patients with severe lung or heart disease to examine whether a particular type of breathing machine (NAVA ventilator) will allow us to remove breathing support more quickly and with less need for sedative medications, when compared to current practice.
