Evaluation of Left Ventricular Function to Predict Weaning Success in the Intensive Care Unit

"All participants will receive a standardized transthoracic echocardiographic (TTE) examination within 2 hours after meeting weaning criteria. The following cardiac function parameters will be recorded:~LVOT Velocity Time Integral (VTI)~Mitral Annular Plane Systolic Excursion (MAPSE)~E/e' ratio~E/A ratio~Mitral Deceleration Time (MDT)~Myocardial Performance Index (Tei index)~The echocardiographic data will be used to investigate the association between left ventricular function and weaning success."
