WebMean Arterial Pressure. As blood is pumped out of the left ventricle into the aorta and distributing arteries, pressure is generated. The mean arterial pressure (MAP) is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP) according to the following relationship, which is based upon the ... WebBlood pressure (BP) is determined by cardiac output (CO) and total peripheral resistance (TPR), as represented by the formula BP = CO x TPR. Cardiac output (CO) is affected …
