Variations of cardiac output are frequent in pregnant women during obstetrical procedures, and may participate to poor foetal outcomes through decrease of uteroplacental bloodflow. Thus, monitoring maternal cardiac output appears of major interest, as it would open the way to early initiation of hemodynamic supportive management.

The ccNexfin© is a non-invasive hemodynamic monitoring device, whose relevance for continuous monitoring of cardiac output has been reported in a non-pregnant population.

The hypothesis is that ccNexfin© gives acceptable measurement of maternal cardiac output in pregnant women.
