Question 1

CO=5 L/min @rest
with Exercise doubles HR and SV
Find CO

Answer 1

COr=5
5=HRSV
COe=2HR2SV
COe=4HR*SV
COe=4(5)
=20

Question 2

HR 80 bpm
EDV 110 ml
ESV 60 ml
Find CO

Answer 2

CO=80(110-60)
=CO (ml)
CO(ml)=4000
4000/1000=4 L/min

Question 3

EDV 90ml
ESV 25 ml
R-R 0.9s
FIND CO

Answer 3

CO=(60/0.9)*(90-25)
CO=4.36L/min

Question 4

HR 70 bpm
SV 70 cc
Find CO

Answer 4

CO=(70)(70)
COml/1000
=4.9

Question 5

HR 60 bpm
EDV 135ml
ESV 85 ml
FIND CO

Answer 5

CO=60*(135-85)
=3L/min

Question 6

EDV=180ml
R-R interval=750msec
EF=0.70
FIND SV

Answer 6

SV=180*70
convert to seconds/1000
126

Question 7

LV contains 170cc
EF 60%
70bpm
FIND CO

Answer 7

CO=(70)(0.6170)

Question 8

EDV 120 ml
ESV 70 ml
HR 88bpm
FIND CO

Answer 8

CO=88(120-70)
=4.4

Question 9

R-R 1.2 s
EDV 133 ml
ESV 48 ml
FIND CO

Answer 9

CO=(60/12)(133-48)
