Ultrasound Evaluation of Cardiac Function During Spontaneous Breathing Trials
Recruiting now · Not applicable
Conditions studied: Weaning Invasive Mechanical Ventilation, Weaning-induced Pulmonary Edema, Weaning Failure of Mechanical Ventilation, Spontaneous Breathing Test, Intensive Care Units (ICUs)
In brief
The goal of this clinical trial is to evaluate the evolution of a cardiac ultrasound index (E/E') during 3 spontaneous breathing trials in Intensive Care Unit (ICU) adults (over 18 years) patients at risk for weaning failure. The main objective is to find out which spontaneous breathing trial is the least demanding in terms of heart work. Investigators will compare 3 consecutive spontaneous breathing trials in a random order to see if one is superior to the others. Participants will not have to perform any specific procedure apart from breathing without respiratory support during the spontaneous breathing trial. During these trials, the investigator will perform cardiac ultrasound measurements.
