Methods: This will be a multi-center centered, pragmatic, double blinded RCT. Mechanically ventilated patients in the ICU, who are deemed ready to be extubated will be included. All patients will have a CLT done prior to extubation. The results of the CLT in the intervention arm will be communicated to the treating physician, and decision to extubate will be left to the treating team, while the results of the CLT for patients in the control arm will not be communicated to the treating physician, and the patient will be extubated, regardless of the result of the CLT.
