blood pressure Flashcards
1
Q
describe blood pressure in the arteries and veins
A
arteries - pulsate - reflects beating heart
veins - continuous - loss of forward motion
2
Q
What is MAP
A
mean arterial pressure
3
Q
how is MAP calculated
A
diastolic + (systolic - diastolic)/3
4
Q
why is MAP not an average of diastolic and systolic
A
because they do not last for equal times
5
Q
what are normal blood pressure readings
A
systolic - 120mmHg
diastolic - 80mmHg
MAP - 93mmHg
6
Q
what factors affect blood pressure
A
age - arteries become stiffer with age
gender - men have higher BP generally
7
Q
what happens to blood pressure during dynamic exercise
A
mean - stays the same
diastolic - diastolic decreases
systolic - systolic increases
8
Q

A
mean - rises
diastolic - rises
systolic - rises
