Helping Patients Take Their Next Breath

VentFree™ Muscle Stimulator

A respiratory electrical muscle stimulator that is designed to reduce the number of days a patient spends on mechanical ventilation.

Clinical Background

Over one million patients in the United States (US) are estimated to undergo mechanical ventilation (MV) every year. Approximately half of them have difficulty weaning from MV, and many end up requiring prolonged ventilator support. In the US, the overall health-care cost of these patients in the acute care setting is estimated to be more than $16 billion annually. Furthermore, patients requiring prolonged MV are susceptible to a wide range of clinical complications and excess mortality. The current standard of care to wean patients requiring prolonged MV is to have them undergo daily spontaneous breathing trials (SBTs). These trials are carried out using a variety of strategies intended to progressively reduce the extent of MV support while, concurrently, reconditioning the respiratory muscles weakened during the preceding pre-weaning period of MV. This process can last between days and months. In the most severe of cases, patients may never wean from MV. Unfortunately, there are presently no medical devices or medications that can accelerate the process of weaning from MV and reduce the number of ventilator-dependent patients.

How Can The VentFree Muscle Stimulator Help?

The VentFree muscle stimulator is an electrotherapy device that applies stimulation to the abdominal wall muscles in synchrony with mechanical ventilation. It is being designed to reduce the time to wean patients from mechanical ventilation. The VentFree muscle stimulator is not available for sale in the United States. Check back here in the coming months for more updates on the product.
