What is blood pressure? Where does the pressure come from?
|
- force exerted on walls of artery
- by pulsing blood under pressure from heart |
|
|
What happens during diastolic pressure?
|
- ventricles relax
- diastolic blood pressure = minimal pressure exerted against arterial walls |
|
|
How do you identify hypertension? Think about the 'high' effect
|
- diastolic readings higher than 90 mm Hg
- systolic readings higher than 140 mm Hg |
|
|
What is orthostatic hypotension? Think about getting up for school, it's a drag!
|
- aka postural hypotension
- occurs in normotensive person - low blood pressure when rising to upright position |
|
|
What does pulse pressure indicate? Provide an example
|
- difference between systolic and diastolic pressure
- ex. blood pressure 120/80, pulse pressure = 40 |
|
|
What happens during systolic pressure?
|
- heart's contraction forces blood under high pressure into aorta
- peak of maximum pressure ejected |
|
|
How do you identify hypotension? Think Lil' Jon
|
- systolic blood pressure falls to 90 mm Hg or lower
|
|
|
List three examples that contribute to hypotension
|
- dilation of arteries in vascular bed
- loss of substantial amount of blood volume - failure of heart muscle to pump adequatey |
