Utilization of impedance cardiography in noninvasive assessment of hemodynamic status in cirrhotic patients.

Background/aims: This study aimed to assess hemodynamic alterations noninvasively using a dedicated device Task Force® Monitor providing various hemodynamic data utilizing impedance cardiography and beat-to-beat blood pressure analysis via a vascular unloading unit.

Methods: Forty-seven patients with cirrhosis awaiting hepatic transplantation and 26 healthy volunteers matched for age and gender were enrolled. Basic hemodynamic status of these patients (following temporary interruption of any drugs affecting the cardiovascular system) was evaluated noninvasively by Task Force® Monitor with patients in the supine position.
