Jet ventilation through jet stylets.
To the Editor-The case report by Baraka’ of jet ventilation through an airway exchange catheter (Cook Critical Care, Bloomington, IL) complicated by tension pneumothorax and cardiac asystole highlights some of the serious dangers of jet ventilation. I would like to focus on three aspects of the case report. The lessons from these can be added to the recommendations made by Baraka at the end of ...
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 کاملVentilation and Fan Pressure Optimization for VAV Systems
Meeting today's ventilation and comfort requirements in multiple-space VAV systems can be challenging. Building heating and cooling loads are typically not static; therefore VAV systems need to be flexible to respond to the continually changing outdoor conditions and occupant activities. To optimize comfort and minimize energy usage in this dynamic environment, the HVAC control system must also...
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...
متن کاملOxygen jet ventilation for microlaryngoscopic procedures.
Sir,—Intermittent jets of oxygen may be used to ventilate patients undergoing microlaryngoscopy with a Venturi injector or by flushing oxygen directly through a small-bore endotracheal tube as we have used in 10 adult patients (table I). The patients were premedicated with pethidine 75 mg and atropine 0.6 mg and anaesthesia was induced with propanidid 250-500 mg followed by suxamethonium 100 mg...
