Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Successful weaning is defined as sustained spontaneous breathing for at least 48 h after extubation. Failed weaning is defined as need for reintubation / NIV within 48 h of extubation.Timepoint: The patients who meet eligibility criteria will be assessed after 30 minutes of SBT for readiness to extubate, then ventilator indices (HR, MAP, RSBI, MV & Pao2/ Fio2) will be recorded at the end of successful SBT. | — |

| Successful weaning is defined as sustained spontaneous breathing for at least 48 h after extubation. Failed weaning is defined as need for reintubation / NIV within 48 h of extubation.Timepoint: The patients who meet eligibility criteria will be assessed after 30 minutes of SBT for readiness to extubate, then ultrasound indices like diaphragmatic thickness, diaphragmatic excursion and speed of diaphragmatic contraction will be recorded at the end of successful SBT. | — |
