High-frequency oscillatory ventilation was first described in 1972 [8] and is used in neonates and adult patient populations to reduce lung injury, or to prevent further lung injury. [9] HFOV is characterized by high respiratory rates between 3.5 and 15 hertz (210 - 900 breaths per minute) and having both inhalation and exhalation maintained by ...
The SensorMedics High-Frequency Oscillatory Ventilator is a patented high-frequency (>150 R f) mechanical ventilator designed and manufactured by SensorMedics Corp. of Yorba Linda, California. After a series of acquisitions, Vyaire Medical, Inc. marketed the product as 3100A/B HFOV Ventilators. [ 1 ]
In a HFV-A scenario, the ventilator uses pressure to apply an inspiratory breath and then applies an opposite pressure to force an expiratory breath. In high-frequency oscillatory ventilation (sometimes abbreviated HFOV) the oscillation bellows and piston force positive pressure in and apply negative pressure to force an expiration. [15]
Pendelluft is one mechanism by which ventilation occurs during High-frequency oscillatory ventilation [6] A final example of pendelluft is if two separate individuals are mechanically ventilated with one ventilator, as might be considered during a shortage of ventilators (such as during a pandemic ).

The most commonly used high frequency ventilator and only one approved in the United States is the 3100A from Vyaire Medical. It works by using very small tidal volumes by setting amplitude and a high rate set in hertz. This type of ventilation is primarily used in neonates and pediatric patients who are failing conventional ventilation. [46]
Heated humidified high-flow therapy, often simply called high flow therapy, is a type of respiratory support that delivers a flow of medical gas to a patient of up to 60 liters per minute and 100% oxygen through a large bore or high flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
