High-frequency ventilation

The Journal of Pediatrics, 1984
Complete physiological understanding of HFV requires knowledge of four general classes of information: 1) the distribution of airflow within the lung over a wide range of frequencies and VT (sect. IVA), 2) an understanding of the basic mechanisms whereby the local airflows lead to gas transport (sect.

High-frequency Ventilation

Clinics in Perinatology, 2021
High-frequency ventilation (HFV) is an alternative to conventional mechanical ventilation, with theoretic benefits of less risk of ventilator lung injury and more effectivity in washout CO2. Previous clinical studies have not demonstrated advantages of HFV in preterm infants compared with conventional ventilation, so rescue HFV has been used when ...

High frequency ventilation

Journal of Paediatrics and Child Health, 1997
Abstract:The 1990s have seen a dramatic resurgence of interest in high frequency ventilation (HFV). The role of HFV in the rescue of infants failing conventional mechanical ventilation (CMV) is now relatively well established. However, the wider role of HFV in the routine management of respiratory failure in the newborn is more contentious.

High-Frequency Ventilation

Seminars in Respiratory and Critical Care Medicine, 1998
High-frequency ventilation (HFV) provides respiratory gas exchange using positive airway pressure-driven tidal breaths that are often smaller than anatomic dead space and breathing frequencies several times faster than normal. Gas transport with HFV involves nonconvective mechanisms such as Taylor dispersion, coaxial flow, and augmented diffusion ...

High-Frequency Percussive Ventilation

Critical Care Medicine, 2005
To review the technique and clinical application of high-frequency percussive ventilation in critically ill patients.Literature search and descriptive review.High-frequency percussive ventilation is a time-cycled, pressure-limited mode of ventilation that delivers subphysiologic tidal volumes at rates that can exceed 500 breaths/min.

Nasal High-Frequency Ventilation

Clinics in Perinatology, 2021
Noninvasive high-frequency oscillatory (NHFOV) and percussive (NHFPV) ventilation represent 2 nonconventional techniques that may be useful in selected neonatal patients. We offer here a comprehensive review of physiology, mechanics, and biology for both techniques.
