Open Access Abstract Introduction The ventilator and the endotracheal tube impose additional workload in mechanically ventilated patients breathing spontaneously. The total work of breathing WOB includes elastic and resistive work. In a bench test we assessed the imposed WOB using 3100 A 3100 B SensorMedics high-frequency oscillatory ventilators. Methods A computer-controlled piston-driven test lung was used to simulate a spontaneously breathing patient. The test lung was connected to a .
