Objective: The most efficient recruitment maneuver (RM) for oxygenation in patients under mechanical circulatory support with acute respiratory distress syndrome (ARDS) has not been described yet. In this study, we have evaluated the effects of three recruitment maneuvers on oxygenation and intracranial pressure. Materials and Methods: 20 sheep have been randomly grouped as follows: ARDS control, ARDS+TV(Tidal Volume), ARDS+CPAP(Continuous Positive Airway Pressure), ARDS+PEEP(Positive End Expiratory Pressure). Arterial blood gas tests have been done before ARDS, after ARDS, and 5,10, and 30 minutes after the maneuver. Intracranial pressures had been followed up. Results: There was a statistically significant increase in Pa02 (Partial arterial oxygen pressure) values in all groups 5 minutes after RM (P < 0,01). There was a statistically increase in Pa02 values in all groups 10 and 30 minutes after the RM (P < 0,01). TV group had significantly more increase in PaO2 increase at the 30th the other groups (P < 0,01). CPAP group had more increase in intracranial pressures just after the RM and at 5 and 10 minutes after the RM. This increase was statistically significant (P < 0,01). All groups had similar intracranial pressure values 30 minutes after the RM. There was no statiscally signifciant difference between the groups (P > 0,05). Conclusion: ICP monitorisation should be carried out in patients with ARDS while performing recruitment maneuvers.
