The aim of this study is to determine, whether a liberal transfusion strategy is helpful to liberate patients from prolonged invasive mechanical ventilation.
Patients who are difficult to wean according to the criteria by Boles et al  are limited by the capacity of their respiratory muscles.
Improved oxygen delivery achieved by blood transfusions however is known to decrease the work of breathing  and thus in theory can improve weaning success .
This study is designed as a prospective, randomized, open labeled blinded End-point evaluation to test the hypothesis that a liberal transfusion strategy decreases the time needed for weaning.
