Abstract Introduction Non-invasive ventilation NIV with a helmet device is often associated with poor patient-ventilator synchrony and impaired carbon dioxide CO2 removal which might lead to failure. A possible solution is to use a high free flow system in combination with a time-cycled pressure valve placed into the expiratory circuit HF-BiPAP . This system would be independent from triggering while providing a high flow to eliminate CO2. Methods Conventional pressure support ventilation PSV and time-cycled biphasic pressure controlled ventilation BiVent delivered by an Intensive Care Unit ventilator were compared to HF-BiPAP in an in vitro lung model .
