Cardiac outputDopplerStroke volumeVentricular functionAssessment of cardiac output (CO) and stroke volume (SV) is essential to understand cardiac function and hemodynamics. These parameters can be examined using three echocardiographic techniques (pulsed-wave Doppler, two-dimensional [2D], and three-...
Arterial pulse waveform analysis.These calculate the cardiac output from shock waves created by blood flow. Low Output If your heart doesn’t pump enough blood to supply your body and tissues, it could signalheart failure. Low output also could happen after you’ve lost too much blood, had a...
In order to calculate stroke volume, use the formula for cardiac output. Plug in the cardiac output and the heart rate and solve for the stroke volume using simple Algebra. What is normal cardiac output? In an adult at rest, the normal cardiac output ranges from 5-6 Liters per minute. ...

OBJECTIVE: To review the literature about the effect of normal pregnancy on cardiac output, with special attention to study design, measurement technique, position of the subject, and parity. DATA SOURCES: For studies from the period 1955-1987, we examined Cumulated Index Medicus (National Library...

Objectives: To determine the direction and magnitude of change in cardiac output (CO) during pregnancy. Study design: We performed serial measurements of CO on five occasions from 24 weeks gestation to term and once during the puerperium in 26 normal pregnancies (156 measurements) using Doppler ul...
