Answer 12

treadmill test

Question 13

claudication is ___

Answer 13

extremity pain during exercise caused by low blood flow

Question 14

Treadmill Test

≤ ___% elevation at 1.5 miles/hour

Answer 14

≤12% elevation at 1.5 miles/hour for 5 mins or until symptoms increase to such severity to stop

Question 15

post exercise ABIs are obtained immediately and then every ___ minutes until pressures return to normal

Answer 15

2 minutes

Question 16

ankle pressures that drop to low or unrecordable levels immediately after exercise and then increase to resting levels < 6 mins suggest ____

Answer 16

single level obstruction

Question 17

ankle pressures that drop to low or unrecordable levels immediately after exercise and then increase to resting levels > 6 mins suggest ____

Answer 17

multilevel obstruction

Question 18

___ is an alternate method to obtain Doppler signals when mobility, lungs, and heart are compromised

Answer 18

reactive hyperemia

Question 19

reactive hyperemia = post exercise ankle pressures ____ 17% to 34%

Answer 19

reactive hyperemia = decrease in ankle pressures post exercises

Question 20

single-level disease = ankle pressure drop ___ 50%

Answer 20

single-level disease = ankle pressure drop < 50%

Question 21

multilevel disease = ankle pressure drop ___ 50%

Answer 21

multilevel disease = ankle pressure drop > 50%
