What this Trial Is About
This study aims to evaluate the correlation between stroke volume measurements obtained by transthoracic echocardiography and bioreactance-based noninvasive cardiac output monitoring. The primary objective is to assess the level of agreement between these two modalities in critically ill patients.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Age 218 years

- Enrollment within 24 hours of ICU admission
You will not qualify if you...
- Pregnancy
- Known severe aortic valve disease or dynamic left ventricular outflow tract obstruction
- Morbid obesity (BMI > 40) that precludes accurate echocardiographic imaging
- Presence of cardiac arrhythmias (e.g., atrial fibrillation with rapid ventricular response) affecting stroke volume measurements
- Implanted cardiac assist devices (e.g., LVAD, pacemaker dependency)
- Imminent death or decision for comfort care only
