Dec 8, 2022 · HFJV resulted in improved ventilation at lower peak and mean airway pressures, as well as more rapid radiographic improvement of pulmonary interstitial emphysema, in comparison with rapid-rate CV.

Choose HFJV for greater ventilator efficiency, improved physiologic impacts, easier operation, and increased therapeutic flexibility. Learn more about the fundamentals of High-Frequency Jet Ventilation, and why it’s superior to other modes of ventilation.

The Bunnell Life Pulse (www.bunl.com) is a flow interrupter that uses a pinch valve to generate a stream of high frequency pulses. These rapid pulses of fresh gas generate the tidal volumes, which allow ventilation to occur primarily from flow streaming (Taylor Dispersion), which allows ventilation to occur even with below dead space tidal volumes.

May 25, 2022 · When vulnerable patients need vital care, Bunnell sets the standard. Bunnell’s High-Frequency Jet Ventilator provides superior physiologic impacts and unique therapeutic flexibility. It’s also highly effective and easy to operate. Learn more about the life-saving technology that has been saving babies since 1988.

The Life Pulse High Frequency Jet Ventilator (HFVJ) is a microprocessor-controlled infant ventilator capable of delivering and monitoring between 240 and 420 breaths/min; hence, HFJV delivers very small tidal volumes at supra-physiological frequencies.

Dec 8, 2022 · Guidelines for HFJV use in neonates, focusing on initial settings, adjustments for various clinical scenarios, and optimizing respiratory outcomes.

HFJV utilizes delivery of oxygen using small VT (<2 mL/kg) at very fast rates (100 to 400 breaths/minute). Gas exchange during HFJV occurs by several mechanisms: mass movement, enhanced molecular diffusion, coaxial gas flow, and pendelluft movement.

High-frequency jet ventilation (HFJV) describes a technique of mechanical respiratory support based on the delivery of gases under conditions of constant flow and low pressure. Among the benefits ascribed to HFJV are lessened interference with hemodynamic function and reduced danger of barotrauma.

May 10, 2022 · High-Frequency jet ventilation is a well-established form of mechanical ventilation that delivers short bursts of high-velocity gas into the endotracheal tube at rates of 240–660 cycles/min. HFJV is the preferred mode of ventilation in the treatment of airleak,...

May 1, 2021 · High-frequency ventilation is commonly utilized with neonates and with children with severe respiratory failure. Both high-frequency oscillatory ventilation (HFOV) and high-frequency jet ventilation (HFJV) are used extensively in neonates. HFJV can also be used in older, larger children.
