2026년 7월 8일 업데이트: Angela Bianco, Icahn School of Medicine at Mount Sinai

TREMOFLO: Gestational Changes in Hemodynamics and Respiratory Mechanics in Association With Pre-eclampsia

This study focuses on elucidating the changes of hemodynamics assessed by USCOM and respiratory mechanics assessed by impedance oscillometry (IOS) over the course of pregnancy and the postpartum period. Additionally, to understand how these changes over the course of gestation relate to the development of preeclampsia.
