Summary

Echocardiographic measurement of inferior vena cava (IVC) collapsibility index (CI) with automated software analyses has been introduced. This study aims to assess the accuracy of IVC-CI (caval index) measurements as well as the ability to track fluid responsiveness (FRes) over time comparing the automated echocardiographic method with the pulse pressure variation (PPV) technique and the manual echocardiographic method in cardiac surgery patients.

Detailed description

It is expected to have insights about the concordance rate. The automated echocardiographic method of measuring CI method may or may not meet the criteria for interchangeability with the thermodilution technique or the manual echocardiographic method.

Conditions

• Hemodynamic Monitoring
• ICU
• Cardiac Surgery

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Automated echocardiographic inferior vena cava measurement	Patients will be place in supine position. view: subcostal view, importantly supine is standard position for IVC measurement, the IVC is larger in the right lateral decubitus position and vice versa, alternatively directly through a transhepatic approach. Measures will be performed in the two dimensional mode close to the hepatic vein (1 - 3cm from the IVC connection to the right atrium). The IVC will be measured by MM-Mode manually and with the automated mode (both measures will be recorded. In the manual mode this measure requires concurrent utilization of M-Mode and two dimensional mode
