Aims: To compose a normogram regarding cardiac output during pregnancy measured with ultrasonic cardiac output monitor (USCOM), a non‐expensive simple continuous wave Doppler device and to investigate if this machine could be useful for haemodynamic monitoring during pregnancy. 
Non-Invasive Methods for Maternal Cardiac Output Monitoring
In a non-obstetric population, the optimization of cardiac output (CO) had been shown to improve survival and to reduce postoperative complications, organ failure and the length of stay 1 . CO
Maternal hemodynamics in normal pregnancy: reference ranges and role of maternal characteristics
The main aim of this study was to construct reference ranges of maternal central hemodynamic parameters during pregnancy. The second aim was to determine the maternal and pregnancy characteristics

TLDR
Methods and devices for the measurement of CO are described and compared, and recommendations are formulated for their use in pregnancy with the aim of standardizing the assessment of CO and peripheral vascular resistance in clinical practice and research studies on maternal hemodynamics.
Non-invasive assessment of maternal hemodynamics in early pregnancy.
TLDR
Applanation tonometry and Doppler Ultrasound for assessment of maternal hemodynamics in early pregnancy revealed similar associations between different hemodynamic parameters and maternal characteristics as have previously been reported in advanced pregnancy and non-pregnant subjects.
Non-invasive cardiac output monitoring (NICOM®) can predict the evolution of uteroplacental disease-Results of the prospective HANDLE study.
TLDR
NICOM® derived maternal haemodynamic profile at 14 weeks' gestation has the novel potential to identify pregnancies which will ultimately develop uteroplacental disease.

To determine if hemodynamic assessment in ‘low‐risk’ pregnant women at term with an appropriate‐for‐gestational age (AGA) fetus can improve the identification of patients who will suffer maternal or
Accuracy and precision of USCOM versus transthoracic echocardiography before and during pregnancy.
TLDR
Monitoring hemodynamic status throughout pregnancy may help in identifying women with maladaptation predisposing to hypertensive complications and therefore absolute values of USCOM and TTE cannot be used interchangeably.
Accuracy and precision of the ultrasound cardiac output monitor (USCOM 1A) in pregnancy: comparison with three-dimensional transthoracic echocardiography.
TLDR
USCOM has acceptable agreement with 3D-TTE for the measurement of CO in pregnancy, particularly in the FT mode, and the positive bias of the USCOM may be due to the hyperdynamic cardiovascular state in pregnancy.

TLDR
First trimester screening of maternal haemodynamics may allow for earlier detection of circulatory derangements, selection of patient precise interventions, and improved maternal-foetal outcomes.

Non-invasive cardiac output determination by two-dimensional independent Doppler during and after cardiac surgery.
TLDR
Using the ultrasonic cardiac output monitoring (USCOM) device it is possible to determine noninvasive beat-to-beat CO in postcardiac surgery patients without the possible complications associated with invasive right heart catheterization.
A longitudinal study of cardiac output in normal human pregnancy.
TLDR
The mitral flow velocity findings suggested decreased ventricular compliance or increased preload in late pregnancy, and left ventricular mass increases because of increased wall thickness.
Noninvasive maternal stroke volume and cardiac output determinations by pulsed Doppler echocardiography.
TLDR
The findings verify the accuracy of an important noninvasive technique for quantitating maternal stroke volume and cardiac output by pulsed Doppler echocardiography and should provide an alternative approach to invasive monitoring in the study of normal and abnormal maternal circulatory hemodynamics.
Clinical evaluation of USCOM ultrasonic cardiac output monitor in cardiac surgical patients in intensive care unit.
TLDR
The USCOM monitor is accurate, rapid, safe, well-tolerated, non-invasive and cost-effective in intensive care monitoring, but its suitability for use in high and low cardiac output states requires further validation.
New perspectives in the assessment of cardiac chamber dimensions during development and adulthood.
TLDR
Because height is a nonderived variable that relates linearly with cardiac dimensions independent of age, it offers a simple yet accurate means of assessing the normalcy of cardiac dimensions in children and adults.
Maternal Hemodynamic Changes Associated with Furosemide Treatment
TLDR
While furosemide improved the hyperdynamic circulation in pregnancy, it did not lower blood pressure or cause clinically significant vasoconstriction.
Maternal Cardiovascular Hemodynamic Adaptation to Pregnancy
TLDR
Myocardial contractility seems to be increased during all trimesters of pregnancy, thus gradually provoking the development of a mild ventricular hypertrophy, which also begins during early pregnancy.
CRITICAL CARE ISSUES FOR THE NEPHROLOGIST: The Pulmonary Artery Catheter in Critical Care
TLDR
Goal of high level invasive monitoring of cardiopulmonary function with pulmonary artery catheterization are organ salvage and minimizing complications associated with critical illness.
