Abdominal Functional Electrical Stimulation

Abdominal functional electrical stimulation does not require patient cooperation. Prior studies found that abdominal functional electrical stimulation can acutely improve respiratory function. Two pilot randomized trials of VentFree in critically ill mechanically ventilated patients found high treatment compliance and no serious device-related adverse events. Abdominal functional electrical stimulation applies neuromuscular electrical stimulation to abdominal wall muscles in synchrony with exhalation.
