Blood pressure is defined as the product of:
D i.e. Peripheral resistance x cardiac output The overall blood flow in circulation of adult at rest is about 5 liter/min which equals to cardiac output because it is the amount of blood pumped by hea per unit time. So Blood pressure = Cardiac output x peripheral resistanceQ or Blood flow (Q) x resistance (R) Venous returnQ = MSFP -- RAP MSFP = Mean systemic filling pressure = Right RAP atrial pressure RVR RVR = Resistance to venous return
Systolic pressure x pulse
Diastolic pressure x pulse rate
Pulse pressure x pulse rate
Cardiac output x peripheral resistance
