Transtracheal jet ventilation may be used even with partial airway obstruction. Airway obstruction below the vocal cords that renders exhalation difficult or impossible is a relative contraindication. Bed turned 90 degrees (Anesthesia on the right side of bed) prior to patient entering room.

2012年10月8日 · HFJV is a versatile, safe and effective technique with growing indications for elective and emergency use. This article aims to give the reader an understanding of the basic science necessary to practice HFJV safely, and increase familiarity with the equipment and techniques used.

High-frequency jet ventilation (HFJV) parameters and settings: Driving pressure: major determinant of tidal volume. Driving pressure settings are usually 20–25 psi in adults, with a maximum of 50 psi

Jet ventilation is a commonly used modality for the oxygenation of patients undergoing maxillofacial and laryngotracheal surgery. It is a highly versatile way of providing oxygenation, enabling gas delivery at multiple points along the airway.

2023年1月29日 · Advances in jet ventilation tube design have facilitated safe anesthesia for laryngeal surgery. High-frequency jet ventilation (HFJV) via a catheter placed in the cricothyroid membrane is useful for oxygenating patients undergoing microlaryngcopic and laser surgery.

A jet frequency of 8–10 min21 allows adequate time for exhalation via passive recoil of the lung and chest wall and prevents air-trapping and build up of pressure in small airways.

Assuming the peak inspiratory pressures are <40cmH2O, a trial of jet ventilation is instituted on ALL patients for no less than 30 minutes. The purpose of this trial is to: If Jet ventilation is used for the mapping and ablation, an ABG will be obtained in the following instances: 15 minutes after instituting Jet ventilation.

Elective use of jet ventilation includes management of the anticipated difficult airway using pre-emptive placement of a trans-tracheal jet cannula, direct laryngoscopy, and vocal cord surgery.

In anesthesiology, jet ventilation provides an important alternative to conventional ventilation methods, particularly during surgeries that require access to the airway. Its ability to deliver small, rapid bursts of gas makes it invaluable in complex airway management scenarios.

High-frequency jet ventilation allows ventilation through a laryngoscope with a jet or suction channel or a specially designed small-diameter catheter. This provides an unobstructed surgical field and is an effective method of ventilating patients with high-grade laryngeal stenosis or …
