The Food and Drug Administration has issued an Emergency Use Authorization (EUA) for the VentFree Respiratory Muscle Stimulator in order to potentially reduce the number of days adult patients, including those with COVID-19, require mechanical ventilation, according to a press release from Liberate Medical.

In comparison with mechanical ventilation, which is invasive and commonly weakens the breathing muscles, the VentFree system uses noninvasive neuromuscular electrical stimulation to contract the abdominal wall muscles in synchrony with exhalation during mechanical ventilation, according to the press release. This allows patients to begin treatment during the early stages of ventilation while they are sedated and to continue until they are weaned off of ventilation.

A pair of pilot randomized, controlled studies, completed in Europe and Australia, showed that VentFree helped to reduce ventilation duration and ICU length of stay, compared with placebo stimulation. The FDA granted VentFree Breakthrough Device status in 2019.

VentFree has been authorized for use only for the duration of the current COVID-19 emergency, as it has not yet been approved or cleared for usage by primary care providers.
