A recent study from Hawaii showed significantly lower percent mortality with Adaptive Support Ventilation (ASV®).
The retrospective, observational study compared a group of 684 general ICU patients treated with conventional, non-automated ventilation to a second group of 196 patients managed with automated ventilation (ASV). Although there was no significant difference in the duration of ventilation, percent mortality on the ventilator was significantly lower in the ASV group (8.6% vs. 27.3%).
During the discussion, the authors touched on the benefits for clinical staff, noting that there were fewer nuisance alarms and the physicians were called less often for changes related to tidal volume and respiratory rate. They also stated that the closed-loop ventilation process seemed to perform well on the whole spectrum of patients, even those complex ones with multi-system failure ARDS.
