Continuous Non-invasive Hemodynamic Monitoring in Early-onset Severe Preeclampsia: a Comparison of Echocardiography, Bioreactance, and Finger Cuff Measurements

Continuous Non-invasive Hemodynamic Monitoring in Early-onset Severe Preeclampsia: a Comparison of Echocardiography, Bioreactance, and Finger Cuff Measurements

The purpose of this study is to compare the feasibility and accuracy of two methods of non-invasive hemodynamic assessments - bioreactance as assessed by non-invasive cardiac output monitoring (NICOM; Cheetah Medical) and pulse wave analysis as assessed by finger cuff arterial pressure (ClearSite, Edwards Life Sciences) - compared to hemodynamic assessments by intermittent echocardiography in early onset preeclampsia.
