Failure of weaning is associated with longer ventilation duration, prolonged ICU stay, and increased risk of complications and death. Therefore, simple and reliable bedside tools are needed to better understand respiratory muscle function and to help predict weaning outcomes.\n\nThis prospective, observational, single-center study aims to evaluate respiratory muscle function using bedside ultrasound in adult ICU patients with pneumonia receiving invasive mechanical ventilation. The diaphragm, parasternal intercostal muscles, and anterior scalene muscles will be assessed using ultrasound during the weaning process. Measurements will be performed serially, starting from the first day when patients demonstrate meaningful spontaneous breathing effort and continuing until successful extubation, tracheostomy, or ICU mortality.\n\nUltrasound measurements of muscle thickness and thickening fraction will be analyzed in relation to weaning outcomes. In addition, ventilator parameters and commonly used weaning indices will be recorded at the time of each ultrasound assessment. The findings of this study are expected to improve understanding of respiratory muscle involvement during weaning and may contribute to earlier identification of patients at risk of weaning failure.",[24,25,26,27],"Pneumonia","Invasive Mechanical Ventilation","Weaning From Mechanical Ventilation in Care Unit","Respiratory Muscle Dysfunction",[29,30,31,32,33],"Mechanical Ventilation Weaning","Respiratory Muscle Ultrasound","Diaphragm Ultrasound","Parasternal Intercostal Muscle","Anterior Scalene Muscle","NOT_YET_RECRUITING","2026-02-05",{"date":37,"type":38},"2026-02-12","ACTUAL",{"date":40,"type":20},"2026-02-15",{"date":42,"type":20},"2027-02-15",{"name":44,"class":45},"Bursa Sevket Yilmaz Training and Research Hospital","OTHER_GOV"]
