Introduction: The Adaptive Support Ventilation (ASV) mode is one of the most advancedventilation modes. Examining the available scientific texts which analyze thevarious results of applying this mode, would improve the cardiac surgery patients’conditions undergoing this mode. This study has been accomplished in order to recognizeclinical experiences in using this mode in cardiac surgery patients.Design & setting: In this systematic review data banks such as PubMed, Science Direct,High Wire, Ovid and ProQuest and the Google Scholar searching motor wereused. The chosen articles were limited to English language ones. Also the chosen articleswere from 1994 to the end of 2013. The used key words were cardiac surgery,ASV, weaning, ICU and clinical experiences.Participants & Interventions: Based on the relation between the papers and the questionof the study and the expert’s opinion of the research group, the related papers havebeen chosen and analyzed.Measurements and Main Results: Among 105 papers which were found at the end ofsearching in the data banks, 8 completely related papers were chosen. The only variablethat had commonly been considered in all of them was the patients’ disconnectiontime from the mechanical ventilator. The other four variables included intubation time,patients’ ICU and hospital stay, sedative requirements and numbers of ABGs.Conclusions: The results indicate that ASV is a user friendly ventilation mode and candecrease both patients’ ICU & hospital stay and health care expenses due to the decreasedintubation time. Related studies to this research are limited so this means moreconsiderations in this background are suggested.
