In pregnancy there is increased blood volume, heart rate (HR), stroke volume (SV), and cardiac output (CO).Present study was to assess the predictive value of serial measurements of cardiac output between 8 – 32 weeks of pregnancy for prediction of maternal disorders. Cardiac output was measured by thoracic electrical impedance plethysmography at 10 + 2 weeks, 14? + 2 weeks, 18? + 2 weeks, 22? + 2 weeks, 26? + 2 weeks, 30? + 2 weeks of pregnancy. These women were followed till 7 days post-partum.? Pregnant women having high cardiac output developed hypertensive disorders and those having low cardiac output developed Intrauterine growth restriction and oligohydramnios.
