WebAlthough this technique is seldom used to determine CO, it can be calculated by the following equation: CO = VO 2 / (CaO 2 − CvO 2) To calculate CO, the oxygen contents of arterial and venous blood samples are measured, and whole body oxygen consumption is measured by analyzing expired air. Web13 dec. 2016 · Cardiac output is calculated by multiplying the stroke volume by the heart rate. Stroke volume is determined by preload, contractility, and afterload. The normal range for cardiac output is about 4 to 8 L/min, but it can vary depending on the body’s metabolic needs. Cardiac output is important because it predicts oxygen delivery to cells. blank order sheet template free https://b2galliance.com
