Use of a fully closed-loop ventilation mode in long-term ventilated ICU patients: a prospective study.

IntelliVent-ASV® is a closed-loop ventilation mode that automatically adjusts ventilation and oxygenation settings in passive and active breathing patients. The minute volume is adjusted according to end-tidal CO2 (ETCO2) information in passive breathing patients (and respiratory rate in active breathing patients), and oxygenation is adjusted according to SpO2 information. This study reports the ventilation and oxygenation delivered by IntelliVent-ASV® in long-term ventilated ICU patients.
