Frequency 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 کاملRESPIRATION AND THE AIRWAY Frequency dependence of lung volume changes during superimposed high-frequency jet ventilation and high-frequency jet ventilation
Editor’s key points † Superimposed high-frequency jet ventilation (SHFJV) involves simultaneous normal frequency (12–20 min) and high-frequency jet ventilation (HFJV) (.500 min). † SHFJV may improve ventilation and gas exchange compared with HFJValone, but the optimum frequencies for SHFJV are unknown. † In this animal model, end-expiratory and tidal volumes determined by opto-electronic plethy...
متن کاملHigh - 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 کاملSuperimposed high-frequency jet ventilation for laryngeal and tracheal surgery.
OBJECTIVE To describe our experience with superimposed high-frequency jet ventilation (SHFJV), which does not require any endotracheal tubes or catheters, for performing laryngeal and tracheal surgery. DESIGN A case series of 500 patients. SETTING A university medical center. PATIENTS Four hundred sixty adult patients and 40 children in a consecutive sample who required laryngeal or trach...
متن کاملComparison of superimposed high-frequency jet ventilation with conventional jet ventilation for laryngeal surgery.
BACKGROUND New ventilators have simplified the use of supraglottic superimposed high-frequency jet ventilation (SHFJV(SG)), but it has not been systematically compared with other modes of jet ventilation (JV) in humans. We sought to investigate whether SHFJV(SG) would provide more effective ventilation compared with single-frequency JV techniques. METHODS A total of 16 patients undergoing min...
