Experimental model of laryngotracheal stenosis in infants: effects of different high‐frequency jet ventilation patterns on pulmonary parameters

Abstract

The results from our experimental model support the safe and effective clinical use of supraglottic HFJV in infants with tracheal stenosis. Moderate driving pressures provide acceptable pulmonary pressures in normal compliant lungs.

Influence of Tracheal Obstruction on the Efficacy of Superimposed High-frequency Jet Ventilation and Single-frequency Jet Ventilation

“…Nonlinear frequency dependency 10 or obstruction dependency 19 of most of our outcome variables have been reported previously. Therefore, the transformation of parameters was necessary to fit the linear mixed models to our observations (table 1).…”
