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 output is indexed to the patient’s body size by dividing it to the BSA: CI (L/min/m 2) = CO/BSA = SV x HR / BSA. Where BSA (body surface area) is calculated from patient …
