Technical Performance and Reflection Capacity of the Anaesthetic Conserving Device—A Bench Study with Isoflurane and Sevoflurane

摘要

ObjectiveThe anaesthetic conserving device (AnaConDa^®, Sedana Medical, Sundbyberg, Sweden) facilitates administration of isoflurane or sevoflurane by liquid infusion. An anaesthetic reflector inside the device conserves exhaled anaesthetic and re-supplies it during inspiration. In this bench study, we examined the influence of infusion rates and ventilatory settings on the resulting anaesthetic concentrations on patient (Cpat) and ventilator side of the reflector (Closs) to describe its technical performance.
