Assessment of Stroke Volume in Shock Using Echocardiography Versus Bioreactive Impedance

Completed

Conditions studied: Shock, Critical Illness

In brief

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 join

Age: 18 and older, up to 90. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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

You may not qualify if…

• 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
