About this trial
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.
Eligibility criteria
Qualifiers
Age ≥ 18 years
Clinical diagnosis of shock as determined by the treating ICU physician (e.g., hypotension requiring vasopressors or evidence of end-organ hypoperfusion)
Able to obtain informed consent from the patient or a legally authorized representative
Enrollment within 24 hours of ICU admission
Disqualifiers
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)
