High frequency jet ventilation.
Anaesthesia, 1984Summary A case is described where high frequency jet ventilation was used to avoid the cardiovascular depressant effects associated with conventional ventilation. Early weaning from inotropic and ventilatory support proved possible.

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.

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 ...

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.

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, 2005To 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, 2021Noninvasive 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.

High-frequency Oscillatory Ventilation
Anesthesiology, 2004Preliminary results with high-frequency oscillatory ventilation (HFOV) applied in neonates with severe hyaline membrane disease have been promising. Experimental data in surfactant-deficient animals have clearly demonstrated the advantages of HFOV, when compared with conventional mechanical ventilation, in improving gas exchange and pulmonary mechanics

High frequency ventilation applications in the OR
AORN Journal, 1983High frequency ventilation provides effective gas exchange at frequencies between 60 and 2,400 min-1. It can be potentially useful in the operating room for bronchoscopy, laryngoscopy, airway surgery, general surgery, and microscopic neurosurgery.

High-frequency ventilation: A review
Respiration Physiology, 1984As a new mode of assisted ventilation, high-frequency ventilation (HFV) embodies several types of devices, all of which employ tidal volumes much smaller and frequencies much greater than conventional mechanical ventilation (CMV). Due to the smaller swings of airway pressure during HFV, it is thought that some of the drawbacks of CMV may be overcome ...
