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.

High-Frequency Market Making to Large Institutional Trades

The Review of financial studies, 2018
We study high-frequency trader (HFT) marker maker behavior in the presence of large trade packages. HFTs lose money on trading and make money from liquidity rebates.

High-Frequency Magnetics

2019
When the magnetic material is used as the high-frequency devices such as RF inductor, the domain walls do not move; so, a soft magnetic material with an uniaxial magnetic anisotropy is often used in the case. A magnetic field is applied in the direction of the hard axis, and magnetization rotation is used in the soft magnetic material.

On high-frequency insulin oscillations

Ageing Research Reviews, 2008
Insulin is released in a pulsatile manner, which results in oscillatory concentrations in blood. The oscillatory secretion improves release control and enhances the hormonal action. Insulin oscillates with a slow ultradian periodicity (approximately 140 min) and a high-frequency periodicity (approximately 6-10 min).

High-Frequency Audiometry in Children

Scandinavian Audiology, 1988
On the grounds of recent literature and of their own previous studies, the authors have examined a group of 25 normal-hearing children, ranging from 7 to 10 years of age, with high-frequency audiometry. The results were compared with those obtained in a group of young adults.

High frequency oscillation

European Journal of Pediatrics, 1994
During high frequency oscillation (HFO) small volumes are delivered at frequencies up to 40 Hz; both inspiration and expiration are active. Oxygenation is controlled by the mean airway pressure level and carbon dioxide elimination by the delivered volume and, less so, by frequency. In some infants the delivered volume can be 50%-100% of the dead space.

Ventilation at high respiratory frequencies

Anaesthesia, 1982
Summary This paper reviews the development of different methods of ventilation at respiratory rates higher than 60 per minute (1 Hz) along with data on experimental and clinical uses of the techniques. The definitions and terms that have been used for these high rates at the present time are confusing.

Ultrasound Patterns of Vitiligo at High Frequency and Ultra‐High Frequency

Journal of Ultrasound in Medicine
ObjectivesTo detect ultrasonographic anatomical alterations in all the skin layers in patients with vitiligo.MethodsA prospective observational color Doppler ultrasound study was performed in nonsegmental face and/or neck vitiligo patients without a history of previous treatments. Two sites, a lesional area and a contralateral clinically healthy region,
