Assessment of Stroke Volume in Shock Using Echocardiography Versus Bioreactive Impedance

Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Adult patients aged 18 years or older 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
  • * 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
