High-frequency Percussive Ventilation in the Management of Elevated Intracranial Pressure

The Journal of Trauma: Injury, Infection, and Critical Care, 1988
We evaluated 38 patients with combined head injury and respiratory failure requiring manipulation of mean airway pressure in order to achieve satisfactory oxygenation. All patients were initially maintained on conventional ventilatory support. When entry criteria were met, patients were transitioned to high-frequency percussive ventilation (HFPV) and ...

High-Frequency Percussive Ventilation

A & A Case Reports, 2015
We report the case of a 48-year-old woman who developed severe septic shock and lung injury after community-acquired pneumonia. She was supported on arteriovenous extracorporeal membrane oxygenation (ECMO) for 19 days. To facilitate decannulation and separation from ECMO, we began trials of high-frequency percussive ventilation (HFPV) using the ...

Benefits of intratracheal and extrathoracic high-frequency percussive ventilation in a model of capnoperitoneum [PDF]

Journal of Applied Physiology
The present study examines an alternative and innovative mechanical ventilation modality in improving oxygen delivery, CO2 clearance, and respiratory mechanical abnormalities in a clinically relevant experimental model of capnoperitoneum. Our data reveal that high-frequency oscillations combined with conventional ventilation improve gas exchange, with

High frequency percussive ventilation in burn patients: hemodynamics and gas exchange

Burns, 2003
High frequency percussive ventilation (HFPV) is a recent ventilatory mode, which combines conventional cycles with high frequency percussions. HFPV was initially instituted as salvage therapy after acute respiratory failure following smoke inhalation injury achieving in each case a dramatic improvement of blood oxygenation, PaCO(2) and ventilatory ...

Use of High-Frequency Percussive Ventilation to Expand Organ Donor Pool

Journal of Intensive Care Medicine, 2017
A 34-year-old woman was brought in to the emergency department after a motor vehicle accident. She had signs of traumatic head injury with Glasgow Coma Scale score of 3, and her neurological examination was consistent with brain death. She was persistently hypoxic on conventional mechanical ventilation and high-frequency percussive ventilation was ...

Effect of Low Frequency Percussion in Drilling Hard Rock

Journal of Petroleum Technology, 1958
Introduction In the development of a fluid-operated hammer drill for accelerated penetration of hard rock formations in oil wells, a research investigation was conducted to evaluate the percussion effects obtained with different design characteristics and to determine the possibilities of percussion in the low ...

High-frequency percussive ventilation improves perioperatively clinical evolution in pulmonary resection*

Critical Care Medicine, 2009
During thoracotomy, positive end-expiratory pressure is applied to the dependent lung and continuous positive airway pressure (CPAP) inflates the nondependent lung to avoid hypoxemia. These methods do not allow the removal of produced secretions. We hypothesized that high-frequency percussive ventilation(HFPV) can improve both conditions and reduce ...

High frequency percussive ventilation (HFPV). Case reports.

Minerva anestesiologica, 2003
Treatment of acute respiratory failure is still a hot issue in intensive care everyday practice: in the last few years high frequency ventilation techniques have been employed as a therapy for adult respiratory distress syndrome (ARDS) and acute respiratory failure (ARF). We applied high frequency percussive ventilation (HFPV) to 3 patients affected by

Development of an innovative instrument for the online characterization of high frequency percussive ventilators

2009
Sophisticated and expensive equipments are required for measuring the respiratory parameters (pressure and flow) during high-frequency percussive ventilation. The use of pressure transducers of new generation with high sensitivity and reduced response time, proposed in this work, per-mit to simplify the flow measure and to develop a DSP-based system ...
