High - frequency Jet Ventilation
High-frequency jet ventilation (HFJV) describes a technique of mechanical respiratory support based on the delivery of gases under conditions of constant flow and low pressure. Among the benefits ascribed to HFJV are lessened interference with hemodynamic function and reduced danger of barofrauma. The theoretical and technical aspects of HFJV are discussed and the clinical experience with 39 pa...
متن کاملFrequency dependence of lung volume changes during superimposed high-frequency jet ventilation and high-frequency jet ventilation.
BACKGROUND Superimposed high-frequency jet ventilation (SHFJV) has proved to be safe and effective in clinical practice. However, it is unclear which frequency range optimizes ventilation and gas exchange. The aim of this study was to systematically compare high-frequency jet ventilation (HFJV) with HFJV by assessing chest wall volume variations (ΔEEV(CW)) and gas exchange in relation to variab...
متن کاملHigh-frequency jet ventilation during radiofrequency ablation: a case report.
High-frequency jet ventilation (HFJV) has been used in emergency airway scenarios and various surgical procedures. Although substantial literature is available regarding HFJV in these situations, there is only 1 publication to date concerning its use for cardiac radiofrequency ablation procedures. The following case study describes a 49-year-old man undergoing radiofrequency ablation in which H...
متن کاملManual jet ventilation v. high frequency jet ventilation during laser resection of tracheo-bronchial stenosis.
Manual jet ventilation (20 b.p.m.) and high frequency jet ventilation (300 b.p.m.) were compared during laser resection of tracheo-bronchial stenosis under general anaesthesia. Both methods provided similar blood-gas tensions at the 10th min of surgery in patients with tracheal stenosis. In patients with bronchial stenosis high frequency jet ventilation resulted in modest hypercarbia and manual...
متن کاملMeasurement of entrainment ratio during high frequency jet ventilation.
We have measured tidal (VT), entrained (Ve) and "blowback" (Vbb) volumes during high frequency jet ventilation (HFJV) through a Mallinckrodt Hi-Lo Jet tracheal tube in anaesthetized patients. The above volumes were calculated by digital integration of the appropriate regions of flow curves derived from a pneumotachograph placed between the bias flow tubing and the tracheal tube. At a driving pr...
