How do changes in I‑time affect ventilation on VDR?

Learning Objectives:

By the end of this two-part series, listeners should be able to discuss:

1. The physiologic rationale supporting the use of high-frequency percussive ventilation (Volumetric Diffusive Respiration, or HFPV).
2. Patient populations most likely to benefit from HFPV.
3. Key published evidence that informs our use of HFPV in pediatric critical care.
4. An expert approach to managing a patient with HFPV.
5. Next steps in research that will direct our understanding of the use of HFPV in pediatric critical care.
