High-frequency ventilation with an uncuffed endobronchial tube

One-lung ventilation via tracheostomy and left endobronchial microlaryngeal tube.

Corrective measures for compromised oxygen delivery during endotracheal tube cuff deflation with high-frequency percussive ventilation.

OBJECTIVE To determine the effect of endotracheal-tube cuff deflation on airflow and F(IO2) during high-frequency percussive ventilation (HFPV), and explore methods of correcting the cuff-deflation-associated decrease in mean airway pressure and F(IO2) at the carina. METHODS Using a mechanical lung model in our respiratory research laboratory, we measured circuit pressure near the connection ...

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...

Use of high-frequency jet ventilation in neonates with hypoxemia refractory to high-frequency oscillatory ventilation.

OBJECTIVE To describe the response to high-frequency jet ventilation in infants with hypoxemic respiratory failure unresponsive to high-frequency oscillatory ventilation. METHODS This was a retrospective analysis of chart records on demographics, ventilator settings, blood gas analysis and calculated oxygenation index prior to and during the first 7 days of high-frequency jet ventilation in t...

Superimposed high frequency ventilation with conventional mechanical ventilation.

A 73-year-old man with ARDS-multiple organ failure due to Chlamydia psittaci, was successively supported with conventional respiratory techniques. After 48 hours of no clinical improvement, HFV was superimposed to CMV in order to combine the advantages of each one. Since improvement has been seen in all ventilatory parameters, this method is suggested as another mode of ventilation for patients...
