High Frequency Ventilation

Also known as: HFV, high frequency oscillation ventilation, HFOV.

What is high frequency ventilation?

High frequency ventilation is a form of mechanical ventilation that is only used in rare instances when extra protection is needed for the lungs. It involves a high delivery of gas to accommodate rapid respiratory rates.

What happens during the procedure?

There are different forms of high frequency ventilation, and the precise nature of the treatment will vary based on the form that is used. The commonalities, however, involve a machine that delivers air to a catheter, which in turn delivers it to an endotracheal tube to the lungs. The machine delivers air at a high volume to accommodate rapid respiration rates.

Is any special preparation needed? 

High frequency ventilation is not a common mechanical ventilation technique. A doctor will determine whether it is the appropriate approach for your situation.

What are the risk factors?

High frequency ventilation can be dangerous in certain population, including those with respiratory failure or severe airflow obstruction.
