What this trial studies
This clinical trial aims to compare the effectiveness of new non-invasive techniques, the Index of Contractility Monitor (ICON) and the Ultra Sonic Cardiac Output Monitor (USCOM), in measuring cardiac output, systolic ejection volume, and vascular filling in pregnant women. The study will assess these measurements against the gold standard of trans-thoracic ultrasound during the first and third trimesters of pregnancy. Additionally, it will evaluate patient comfort, examination time, and examiner satisfaction with each technique. Participants will be enrolled from the first trimester and monitored until delivery, with specific consultations scheduled for measurements.
Why it matters
Potential benefit: If successful, this study could provide safer and more comfortable methods for monitoring cardiac function in pregnant women.
How similar studies have gone: While the specific combination of techniques in this study may be novel, similar non-invasive approaches have shown promise in other studies.
