High Frequency Oscillatory Ventilation (HFOV) with Dr. Martin Kneyber--Part 2

May 6, 2024

Dr. Martin Kneyber discusses the physiologic rationale for HFOV, patient populations benefiting from it, evidence supporting its use, expert patient management, and future research. Topics include mean airway pressure, chest movement in HFOV, corner frequency's impact on ventilation, optimizing strategies for oxygenation, and CO2 monitoring in critically ill children.

Dr. Martin Kneyber is Chief of the Division of Paediatric Critical Care Medicine at the Beatrix Children’s Hospital, University Medical Center the Netherlands. He is interested in better understanding the respiratory pathophysiology in mechanically ventilated children. His basic science research focuses on ventilator-induced lung injury and its relationship with multiple system organ failure, he is also a principal investigator for PROSpect–Prone and Oscillation pediatric clinical trial.

Learning Objectives:

By the end of this podcast, listeners should be able to discuss:

The physiologic rationale supporting the use of high frequency oscillatory ventilation (HFOV).
Patient populations most likely to benefit from HFOV.
Key published evidence that informs our use of HFOV in pediatric critical care.
An expert approach to managing a patient with HFOV.
Next steps in research that will direct our understanding of the use of HFOV in pediatric critical care.
