Background: Mechanical ventilation is used frequently to provide respiratory support in patient that go to Coronary artery by pass grafting surgery. One of the most common respiratory modes used for patients receiving CABG is Synchronized Intermittent Mandatory Ventilation. Other mode can be used is Adaptive Supportive Ventilation to decrease pulmonary complication. Aim: The general aim of this research is to measure the effects of Adaptive Support Ventilation (ASV) on duration of mechanical ventilation and Hospital Stay in CCU compare with Synchronized Intermittent Mode of Ventilation (SIMV) as controls among patients undergoing CABG surgery. Method: Randomized controlled trial design “single-blind controlled trial” was used in this study. 100 patients, was included and divided into two group, (1) patients on ASV mode; (2) patients on SIMV mode. The study carried out in the cardiac Care Unit at AL-Istishari Arab Hospital (IAH) in Palestine. Results: The results showed that there is no statistically significant difference between ASV and SIMV regarding gender, age and BMI (P>0.05). The percentage of smokers’ hookah among ASV was statistically significant differences compared with SIMV (18% vs. 42.0%, respectively,
P<0.05). The mean of mechanical ventilation duration was lower statically significant in ASV patients compared with SIMV (4.88±0.48 hr. vs. 5.98±0.77 hr. respectively and P < 0.005). By same away, the mean of length of stay in CCU was lower statically significant in ASV patients compared with to SIMV (3.66±0.56 vs. 6.02±0.84 days respectively and P < 0.005). The average number of ABGs in this study was lower statically significant in ASV patients compared with to SIMV (4.00±0.64 vs. 5.86±0.64 respectively and P < 0.005). Finally, the average respiratory rate, SPO2, SBP, DBP, set rate, FIO2, was higher statistically significantly different in ASV compared to SIMV during the first 12 hr. after CABG surgery. The mean of heart rate in ASV groups was lower statistically significant than SIMV groups. There are no statistically significant differences between SIMV and ASV regarding average FIO2, PEEP, IE ratio, SBP, DBP and minute volume.Conclusion: ASV compared to SIMV were statistically significant differences regarding to mechanical ventilation duration, the length of stay in CCU, average number of ABGs, respiratory rate, heart rate, SPO2, SBP, DBP, set rate, and FIO2. In contrast, there is no association between the type of ventilation and socio-demographic characteristics.
