Brief summary

This prospective and observational trial over 55 pregnant women (third trimester) compares non invasive haemodynamic monitoring using Nexfin technology and ultrasonography technic

Interventions

OTHERhaemodynamic evaluation

continous haemodynamic monitoring is performed with digital Nexfin captor in two positions. in the same time transthoracic cardiac ultrasonography is performed to calculate cardiac output using velocity time index of aortic outflow chamber.

Design outcomes

Primary

Measure	Time frame	Description
Cardiac output measure	30 minutes	Cardiac output is measured with non-invasive digital Nexfin technology (ml/min) and compared with transthoracic echocardiographic measure of cardiac output (ml/min) used as reference. Echographic cardiac output (ml/min) is measured as the produce of cross sectional aera of left ventricular outflow track (cm²) multiplied by velocity time index (cm) multiplied by heart rate (beat/min)
