How does high frequency percussive ventilation work?

High frequency percussive ventilation (HFPV) employs high frequency low tidal volumes (100–400 bursts/min) to provide respiration in awake patients while simultaneously reducing respiratory motion.

Is high frequency ventilation used in adults?

High intrathoracic pressures may thus lead to further regional lung injury. HFOV settings in adults are also different from those of pediatric patients. Lower frequencies (4–8 Hz in adult vs 8–12 Hz in pediatric patients) and pressure amplitudes of up to 60 cm H2O are often used in adults.

What is high frequency oscillatory ventilation?

High frequency oscillatory ventilation (HFOV) is a type of mechanical ventilation that uses a constant distending pressure (mean airway pressure [MAP]) with pressure variations oscillating around the MAP at very high rates (up to 900 cycles per minute). This creates small tidal volumes, often less than the dead space.

What is high frequency positive pressure ventilation?

HFV is a new technique of ventilation that uses respiratory rates that greatly exceed the rate of normal breathing. There are three principal types of HFV: High frequency positive pressure ventilation (HPPV, rate 60-150/minute);

What does high-frequency ventilation mean?

High-frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than 4 times the normal value. (>150 (Vf) breaths per minute) and very small tidal volumes. High frequency ventilation is thought to reduce ventilator-associated lung injury (VALI), especially in the context of ARDS and acute lung injury.

High frequency oscillatory ventilation (HFOV) is an alternative method of mechanical ventilation which can help a patient out in specific circumstances, and can be used as a ‘lung protective strategy’ in the management of some severe lung conditions. In short: when a child or infant can no longer move…

What is a VDR ventilator?

The Volume Diffusive Respirator (VDR) ventilator is about the only thing in the last 20 or so years that has had any significant effect on smoke inhalation injury, Barillo said. This is especially important in that smoke inhalation is the single most important factor in predicting survival of burn patients.
