Evaluation of 4 new generation portable ventilators.
BACKGROUND Portable ventilators are increasingly utilized in the intra- and inter-hospital transport of patients. We evaluated 4 portable ventilators, Impact EMV, CareFusion LTV 1200, Newport HT70, and Hamilton T1, in terms of triggering, delivered tidal volume (V(T)) accuracy, battery duration, delivered F(IO(2)) accuracy, and gas consumption. METHODS Triggering was tested using a microproce...
متن کاملAccuracy of automatic tube compensation in new-generation mechanical ventilators.
OBJECTIVE To compare performance of flow-adapted compensation of endotracheal tube resistance (automatic tube compensation, ATC) between the original ATC system and ATC systems incorporated in commercially available ventilators. DESIGN Bench study. SETTING University research laboratory. SUBJECTS The original ATC system, Dräger Evita 2 prototype, Dräger Evita 4, Puritan-Bennett 840. INT...
متن کاملContinuous positive airway pressure in new-generation mechanical ventilators: a lung model study.
BACKGROUND A number of new microprocessor-controlled mechanical ventilators have become available over the last few years. However, the ability of these ventilators to provide continuous positive airway pressure without imposing or performing work has never been evaluated. METHODS In a spontaneously breathing lung model, the authors evaluated the Bear 1000, Drager Evita 4, Hamilton Galileo, N...
متن کاملNew generation neonatal high frequency ventilators: effect of oscillatory frequency and working principles on performance.
BACKGROUND Several new generation neonatal ventilators that incorporate conventional as well as high frequency ventilation (HFOV) have appeared on the market. Most of them offer the possibility to use HFOV in a volume-targeted mode, despite absence of any preclinical data. With a bench test, we evaluated the performances of 4 new neonatal HFOV devices and compared them to the SensorMedics HFOV ...
متن کاملPortable ventilators
Mechanical ventilators used in intensive care units are sophisticated devices. The guiding principle in their design is the provision of optimal lung ventilation. They incorporate precise but sizeable pneumatic components intended to utilize piped gases and mains electricity. However, when transporting patients receiving ventilatory support, these devices are rarely suitable because of their si...
