Question

ww, considering only DIRECT cause and effect (not what your body would do if...), fill in the chart below, evaluate cach factor, then determine if systole (related to Coordigstole (related to TPR) are directly affected. Use Increase (1), Decrease (D), or No Change (N). (OR ARROWS ARE FINE TOO) Expect problems like this on the quiz next week! CONDITION CO HR (Heart rate) Stroke (Cardiac output) CHANGE IN SYSTOLE Peripheral CHANGE IN Resistance DIASTOLE (Viscosity) (Length) area. area) 1/CSA cross sectional (change in Epinephrine (similar to NorEpi) Gaining 5 pounds Acetylcholine Pregnancy (gain of 25-30 pounds and 1 liter blood) Polycythemia (high Ht) Dehydration

Answer 1

CONDITION	HR	SV	CO	CHANGE IN SYSTOLE	V	L	1/CSA2	PERIPHERAL RESISTANCE	CHANGE IN DIASTOLE
EPINEPHRINE	I	I	I	I	D	D	I	D	I
GAINING 5 POUNDS	i	I	I	I	D	D	I	D	I
ACETYLCHOLINE	D	D	D'	D	I	I	D	I	D

CARDIACOUTPUT = SV x HR

CO INVERSELY PROPORTIONAL TO V

CO DIRECTLY PROPORTIONAL TO SYSTOLE

V DIRECTLY PROPORTIONAL TO PR

PR DIRECTLY PROPORTIONAL TO L

PR INVERSELY PROPORTIONAL TO CROSS SECTIONAL AREA

SV DIRECTLY PROPORTIONAL TO DIASTOLE
