Cardiac Output and Cardiac Index – What

WebUsing the Fick Principle ’s equation of ( cardiac output = oxygen consumption/arterio-venous oxygen difference), cardiac output can be calculated. Both methods render normal cardiac output to around 5 litres … WebThe blood concentration of oxygen is expressed as mL O 2 /ml blood, and the VO 2 is expressed in units of mL O 2 /min. If CaO 2 and CvO 2 are 0.2 mL and 0.15 mL O 2 /ml blood, respectively, and VO 2 is 250 mL O 2 /minute, then CO = 5000 mL/min, or 5 L/min. Ventricular stroke volume would be the cardiac output divided by the heart rate. WebCardiac Power Output < 0.6 (Severe left ventricular dysfunction), Pulmonary artery pulsatility index < 1.0 (Severe right ventricular dysfunction) The rationale for only requiring SvO2, MvO2/PaO2, and Hb to calculate CI, is explained in the Med C Guide pages 34-37.
