Summary

Acute circulatory failure (ACF) is a common cause of admission in intensive care unit (ICU). Echocardiography is a widespread tool nowadays for the initial assessment and the hemodynamic monitoring. An interesting data from this exam is the Left ventricular outflow tract (LVOT) velocity time integral (VTI), reflecting stroke volume, and therefore cardiac output. A new tool for automated recording has been developped on the VENUE GE echograph. This study aims at assessing this automated measurement of LVOT VTI compared with the classic manual method.

Conditions

  • Acute Circulatory Failure

Interventions

DEVICE

Echocardiographic exam

An echocardiographic exam is realised after inclusion, measuring especially : * LVOT VTI * Respiratory variation of inferior veina cava diameter For theses two measurements, the manual method is first recorded, and then the automated one is done. For patients that need fluid resuscitation of at least 250mL in less than 10minutes (indication at the discretion of the physician in charge of the patient), a second echocardiography is done according to the same protocol described before.
