Validation of a Non-invasive Hemodynamic Monitor (NexFin) in Pregnant Women

Validation of Non-invasive Monitoring of Blood Pressure and Cardiac Output in Healthy Pregnant Women During Cesarean Section

Blood pressure and cardiac output can be measured invasively in pregnant women. Non-invasive monitoring devices are desirable, but until now, no equipment has proven validity. This study aims at validating the non-invasive monitoring device NexFin (second generation Finometer) in pregnant women.

Validation will be a direct beat-to-beat comparison of data from NexFin and the invasive measurements of blood pressure and calibrated cardiac output as an integrated part of LiDCO Plus. Both comparison of absolute values and the two different devices trending abilities will be analyzed.

Inclusion Criteria:

• Healthy singleton pregnancies at term scheduled for cesarean delivery

Exclusion Criteria:

• Twins, or multiple gestation, pre-eclampsia, gestational hypertension
