Routine use of weaning predictors: not so fast.
Weaning from mechanical ventilation remains a major challenge for critical care physicians. Because subjective criteria are inaccurate, objective measurements consisting of clinical criteria and physiologic tests (weaning predictors) have been used to facilitate decision-making. An integrated weaning index calculated as the product of static compliance and arterial oxygen saturation divided by the frequency-tidal volume ratio appears to be more accurate than other currently available predictors. Despite the accuracy of this new test, a beneficial effect on outcome is yet to be proven.
