Assessment of Process and Outcome of Protocol-based Weaning From Mechanical Ventilation in the Medical Patients

This is a prospective, single-center, observational study to describe characteristics of weaning process and factors associated with duration of weaning and its outcomes in all consecutive adult (aged 19 years and older) patients receiving mechanical ventilation for at least two calendar days in medical intensive care units since November 2017. Details of the patients' weaning process and spontaneous breathing trial (SBT) in addition to clinical, laboratory, and outcome data will be collected in a specified format on the day of the assessment by respiratory care practitioners.
