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 کاملMeasurement of end-expiratory pressure during transtracheal high frequency jet ventilation for laryngoscopy.
An anaesthetic technique using high frequency jet ventilation has been proposed for direct laryngoscopy, but this may expose the patients to the risk of barotrauma. In order to assess this risk, we have measured end-expiratory airway pressure (EEP) through the injector using two three-way solenoid valves mounted in series. At the end of insufflation the first valve was switched off and the appa...
متن کاملTranstracheal high frequency jet ventilation for endoscopic airway surgery: a multicentre study.
Serious complications during high frequency jet ventilation (HFJV) are rare and have been documented in animals and in case reports or short series of patients with a difficult airway. We report complications of transtracheal HFFJV in a prospective multicentre study of 643 patients having laryngoscopy or laryngeal laser surgery. A transtracheal catheter could not be inserted in two patients (0....
متن کاملTranstracheal jet ventilation in a porcine model
Hypoxemia is a frequent event during difficult airway management. We propose to use transtracheal jet ventilation (TTJV) early during the management of complex difficult airway scenarios. The objective of this porcine study is to highlight the benefit of oxygenation via prophylactic TTJV. Eighteen pigs (Sus scrofa) were divided into two equal groups. In Group A, pigs were anesthetized and no lu...
متن کاملVessel dilator cricothyrotomy for transtracheal jet ventilation.
Needle cricothyrotomy is a safe, relatively easy procedure and has been described to enable pulmonary ventilation for patients in both elective and emergency situations. Conventional IV cannulae are short, thin-walled, and easily kinked and, therefore, do not provide a secure system to jet oxygen into the trachea. The vessel dilators of most 7-9 French introducer kits are firm, pliable, resist ...
