WebDuring one cardiac cycle the entire CO and SV pass through the LVOT and AV, making them ideal areas to interrogate, although other locations within the heart and great vessels can be used. Oesophageal Doppler uses the same principles for calculating CO from the descending aorta. SV and CO can be derived as follows, using the AV as an example: WebAug 16, 2024 · CO = HR * SV A cylinder’s area = (π*r2) * h where ‘r’ is the radius of the cross sectional area and ‘h’ is the cylinder’s height. If we model the left ventricular outflow tract (LVOT) as a cylinder, this area would …
