“…at the Y‐piece or ventilator, difficult to interpret ( 11). In order to compensate for the tube resistance with subsequent pressure changes in the ventilator to increase respiratory comfort ( 12, 13), the automatic tube compensation (ATC) concept has arisen ( 14, 15), i.e. continuous calculation of and compensation for the assumed pressure drop over the endotracheal tube during both inspiration and expiration.…”

“…The measured signals were digitized with 100 Hz (12‐bit resolution, SDM863, Burr Brown, Tucson, AZ, USA) and stored on a computer hard disk. ATC was used in inspiration and expiration with a simplified approach compared to the original description ( 6). Most importantly, the ventilator used in this study (Evita 2, Dräger, Lübeck, Germany) did not produce subatmospheric pressure in expiration.…”

“…Automatic tube compensation (ATC) is a new ventilatory option designed to support spontaneously breathing tracheally intubated patients ( 6). The pressure drop across the endotracheal tube is compensated for in inspiration by an increase of airway pressure, and in expiration by a decrease of airway pressure, according to actual gas flow.…”

“…If the ventilator is used for weaning purposes, the additional work of the ventilator-humidifier circuit is superimposed on this workload 4,5 . The effects of various breathing patterns on the respiratory work imposed by the endotracheal tube have been studied extensively [1][2][3][6][7][8] . The performance of various ventilators providing CPAP has also been examined 2 .…”

The effects of continuous positive airway pressure (CPAP) provided by the Siemens Servo 900C ventilator were compared with a continuous flow system (CF-CPAP) in patients weaning from the ventilator. Thirteen patients were studied using both systems at a CPAP level of 0.5 kPa. Additional work of breathing (Wapp) and derived variables were determined in relation to the minute volumes of the patients. The Wapp imposed by the ventilator exceeded the Wapp of CF-CPAP in all patients. The difference in Wapp between ventilator-and CF-CPAP was greater at higher ventilatory needs. The increments in Wapp imposed by the ventilator were positively correlated with the actual end-expiratory pressures (EEP). The EEP increasingly exceeded the preset CPAP level of the ventilator at higher minute volumes. An inspiratory threshold due to a gradient between EEP and preset CPAP greatly increased the Wapp imposed by the ventilator. As this threshold was attributed to the resistance of the PEEP device of the ventilator, it indicates that the additional work related to the expiratory valve should be taken into account when the Siemens Servo 900C ventilator is used for weaning purposes.
