Brief Summary:
In ventilated patients with acute respiratory failure endotracheal suctioning may lead to alveolar derecruitment, which can be monitored by means of functional residual capacity (FRC) measurements. Regional distribution of ventilation can be followed at bedside using electrical impedance tomography. The investigators hypothesize that a FRC guided recruitment strategy, aimed at restoring a baseline FRC value after open endotracheal suctioning, improves oxygenation and regional distribution of ventilation. In addition the investigators research the impact of such a strategy on the inflammatory response to mechanical ventilation.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Supportive Care
Official Title: Functional Residual Capacity Guided Alveolar Recruitment Strategy in Patients With Acute Respiratory Failure After Cardiac Surgery
Study Start Date : October 2010
Estimated Primary Completion Date : December 2011
Estimated Study Completion Date : May 2012


Arm Intervention/treatment
Experimental: FRC guided
Patients receive an alveolar recruitment manoeuvre if FRC falls below 94% of baseline FRC
Procedure: alveolar recruitment manoeuvre
Increase of airway pressures in a stepwise manner from set peak inspiratory pressure/ positive end-expiratory pressure up to 40/15 mbar and back over 2 minutes.
Active Comparator: Saturation guided
Patients receive an alveolar recruitment manoeuvre if peripheral oxygen saturation falls below 90%
Procedure: alveolar recruitment manoeuvre
Increase of airway pressures in a stepwise manner from set peak inspiratory pressure/ positive end-expiratory pressure up to 40/15 mbar and back over 2 minutes.



Primary Outcome Measures :
  1. Regional ventilation [ Time Frame: 6 hours ]
    Regional distribution of ventilation over 6 hours of treatment


Secondary Outcome Measures :
  1. arterial oxygenation and inflammation [ Time Frame: 6 hours ]
    Changes of arterial oxygenation and inflammatory parameters in the blood during 6 hours of treatment
