Weaning indicators
While the criteria for intubation and ventilation have been studied extensively and are recorded in the corresponding guidelines, the specifications for extubation or the temporary interruption of weaning measures are harder to find and are only sometimes evidence-based. Extreme forms of a patient's incapacity to adequately assume the work of breathing can of course be easily identified with blood gas analysis and based on clinical symptoms, but the determination of the right time for weaning or extubation is often difficult in clinical practice. Weaning indicators can significantly support clinical assessment as part of a prolonged weaning process. They include the Rapid Shallow Breathing Index, the occlusion pressure measurement P01, and Negative Inspiratory Force (NIF).
