What degree of change in blood pressure should indicate an immediate termination of exercise because it indicates possible cardiovascular failure?
a. a sudden, significant rise in systolic pressure
b. diastolic pressure increase by more than 15 mmHg
c. a sudden, significant drop in diastolic pressure
d. systolic pressure increasing by more than 15 mmHg
Answer: b. diastolic pressure increasing by more than 15 mmHg
Diastolic pressure increasing by more than 15 mmHg indicates immediate termination of exercise because it indicates possible cardiovascular failure. Diastolic pressure should change minimally or even decrease slightly during even maximal intensity exercise.
