Fick principle - Wikipedia

WebFick's principle states that the arteriovenous oxygen (AV-O 2) difference is inversely proportional to the cardiac output. A normal AV-O 2 difference is about 20–50 mL/L. At low cardiac outputs, greater extraction of oxygen is present from the tissues and the mixed venous saturation is low, resulting in a high AV-O 2 difference. WebThe need to quantify blood flow through the heart has led to the development of different techniques for its measurement. The 3 main approaches are the Fick method, dye … myfax website

WebCalculation of cardiac output and pulmonary blood flow by the Fick method is the routine for use in patients with septal defects and associated shunts. The method depends on the fact that oxygen uptake by the lungs is equal to oxygen consumption in the tissues. WebCardiac output is therefore calculated using the formula: Cardiac output = Oxygen consumption / Arteriovenous oxygen gradient; Normal values: Normal cardiac output is 4-8 L/min; Normal cardiac index is 2.5-4 L/min/m²; Normal stroke volume is 60-100 ml/beat; Normal stroke volume index is 33-47 ml/beat/m²
