Helping Patients Take Their Next Breath

VentFree™ Respiratory Muscle Stimulator

Power to Liberate – Preparing to Wean from Day One of Mechanical Ventilation.


The VentFree respiratory muscle stimulator activates the abdominal muscles in mechanically ventilated patients using proprietary non-invasive electrical stimulation applied during exhalation. As electrical stimulation does not require patient participation, therapy can begin from day one of mechanical ventilation while patients are sedated or delirious. This breakthrough approach, which is quick and simple to use, is intended to prevent abdominal muscle atrophy and reduce the time taken to liberate patients from mechanical ventilation.


Addressing an Unmet Clinical Need

Expiratory muscle atrophy is often found in mechanically ventilated patients and can result in insufficient cough, inadequate secretion clearance and reduced neuromuscular efficiency of the diaphragm. In addition, reduced expiratory muscle strength is associated with weaning failure and delayed extubation.

Patients who require more than four days of mechanical ventilation suffer from high rates of hospital mortality, morbidity and post-discharge complications.

Improving Clinical Outcomes

A pilot randomized controlled trial, which included 20 critically-ill, mechanically ventilated patients, found that mechanical ventilation duration and ICU length of stay were shorter in patients who received stimulation with the VentFree respiratory muscle stimulator compared to those who received placebo stimulation.

Reduced days on mechanical ventilation can potentially lead to reduced morbidity and mortality, improved quality of life and significant savings for the health care provider

The VentFree respiratory muscle stimulator is CE marked and is available for sale within the European Economic Area (EEA). Outside of the EEA, the VentFree respiratory muscle stimulator is an investigational device only and is not for sale.
