Difficult weaning is fortunately a rare occurrence in mechanically ventilated patients in ICU. When faced with this problem, a vast number of factors must be carefully considered simultaneously: physiological adjustment, technical problems (tubing, circuit resistances, ...) . The most promising approach to difficult weaning to date centers on the respiratory muscle function which represents the most common factor allowing weaning success or failure.
