- • Define all terms in the following mathematical relationships and explain why these relationships are valid: a. Pulse pressure = systolic pressure - diastolic pressure b. MAP = diastolic P + 1/3(systolic P - diastolic P) c. MAP= CO x TPR or CO = MAP/TPR (total peripheral resistance is combined resistance of all vessels in systemic circuit) d. MAP = HR X SV x TPR e. Flowarteriole u 1/Rarteriole or Flow = AP/R arteriole note P is pressure and R is resistance ***Note R on its own or expressed as Rarteriole refers to the pressures/flow/resistance in a single location (vessel/arteriole). TPR is the total peripheral resistance in the systemic circuit and any calculation with it as a term refers to MAP, Flow, etc. in the entire systemic circuit. Apply these mathematical relationships to show what happens to blood pressure and distribution of blood when arteriorlar resistance, blood volume, heart rate, or stroke volume changes • State Poiseuille’s Law R=(8Ln ) (ftr"); using this law describe how resistance in a blood vessel changes with changes in blood vessel length, viscosity of blood, and blood vessel radius. In humans describe which factors are relatively constant and which play a significant role in determining resistance to blood flow
