What is considered high frequency ventilation?

High-frequency ventilation (HFV) is a form of mechanical ventilation that combines very high respiratory rates (>60 breaths per minute) with tidal volumes that are smaller than the volume of anatomic dead space [1].

What is high frequency percussive ventilation?

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.

Is high frequency oscillatory ventilation invasive?

Although HFV has been applied in many neonatal intensive care units, nasal high-frequency oscillatory ventilation (nHFOV) is a relatively new non-invasive modality, and evidence for its use is limited.

Is high frequency ventilation used in adults?

High-frequency oscillatory ventilation (HFOV) is a lung-protective strategy that can be utilized in the full spectrum of patient populations ranging from neonatal to adults with acute lung injury. HFOV is often utilized as a rescue strategy when conventional mechanical ventilation (CV) has failed.

Why is high frequency ventilation used?

It reduces the risk of volutrauma and thus helps prevent ventilator-induced lung injury. It also maintains constant alveolar inflation and thus prevents the inflate – deflate cycle and improves oxygenation.

What is high pressure ventilation?

High-pressure non-invasive positive pressure ventilation (NPPV) is a new strategy targeted at maximally reducing arterial carbon dioxide. However, high inspiratory positive airway pressure (IPAP) might cause respiratory adverse events likely to diminish the benefit of NPPV.

What is jet ventilation used for?

Invasive Airway Access Transtracheal jet ventilation is an invasive technique used for oxygenation and ventilation in the management of a difficult airway. Jet ventilation through a rigid bronchoscope is commonly used in the operating room during interventional pulmonology procedures and laryngeal surgery.

What is HFPV?

High frequency percussive ventilation (HFPV) is a specific mode of HFV that has been successfully applied in the treatment of acute respiratory failure after smoke inhalation; it has also been more widely used in pediatric than in adult patients.

What is the difference between an oscillator and a ventilator?

High-frequency oscillation (HFO) ventilation differs from conventional ventilation in that very small breaths are delivered very rapidly (180 to 900 breaths per minute). HFO helps with the opening of collapsed lung tissue by providing constant positive pressure in a person’s airway.

How does high frequency oscillatory ventilation work?

HFOV 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 (less than the dead space of the lung and the circuit).

Which of the following are advantages of high frequency ventilation when compared with conventional ventilation?

High Frequency Percussive Ventilation HFPV improves oxygenation, improves ventilation, and lowers airway pressures (peak, mean, and end-expiratory), compared to other modes of mechanical ventilation.

What are the different types of mechanical ventilation?

The two main types of mechanical ventilation include positive pressure ventilation where air is pushed into the lungs through the airways, and negative pressure ventilation where air is pulled into the lungs.
