High-Frequency Percussive Ventilation Revisited

Journal of Burn Care & Research, 2010
High-frequency percussive ventilation (HFPV) has demonstrated a potential role as a rescue option for refractory acute respiratory distress syndrome and as a method for improving inhalation injury outcomes. Nevertheless, there is a lack of literature examining the practical application of HFPV theory toward either improving gas exchange or preventing ...

High frequency percussive ventilation and low FiO2

Burns, 2012
High-frequency percussive ventilation (HFPV) is an effective rescue therapy in ventilated patients with acute lung injury. High levels of inspired oxygen (FiO(2)) are toxic to the lungs. The objective of this study was to review a low FiO(2) (0.25)/HFPV protocol as a protective strategy in burn patients receiving mechanical ventilation greater than 10 ...

High-frequency percussive ventilation for intercontinental aeromedical evacuation

American Journal of Disaster Medicine, 2011
High-frequency percussive ventilation (HFPV) has been used for the management of patients with smoke inhalation injury for more than 20 years and is considered a standard of care at many burn centers. Because the ventilator is powered by air and oxygen rather than electricity, prehospital use has been limited by largevolume medical gas requirements ...

Performance characteristics of high-frequency percussive ventilation under hyperbaric conditions

Undersea and Hyperbaric Medicine, 2021
Introduction: Safe administration of critical care hyperbaric medicine requires specialized equipment and advanced training. Equipment must be tested in order to evaluate function in the hyperbaric environment. High-frequency percussive ventilation (HFPV) has been used in intensive care settings effectively, but it has never been tested in a hyperbaric

High-frequency Percussive Ventilation for Severe Inhalation Injury

Anesthesiology, 2014
998 April 2014 A HEALTHY 26-yr-old with singed nares, carbonaceous tracheal secretions, and respiratory distress was intubated following a house fire. Bronchoscopy (fig.) revealed soot throughout the tracheobronchial tree consistent with severe inhalational injury.

Use of High Frequency Percussive Ventilation in Inhalation Injuries

Journal of Burn Care & Research, 2006
Inhalation injury causes significant morbidity and mortality, accounting for nearly 80% of non-fire-related deaths and affecting nearly 25% of all patients hospitalized with thermal injury. High-frequency percussive ventilation (HFPV) has been reported to decrease both the incidence of pulmonary barotrauma and pneumonia in inhalation injury.

High-frequency percussive ventilation compared with conventional mechanical ventilation

Critical Care Medicine, 1985
In seven patients with severe respiratory distress, conventional mechanical ventilation and PEEP were used initially for respiratory support, which was changed to high-frequency percussive ventilation (HFPV) at the same level of airway pressure and FIO2.
