2.3 Hypertension Flashcards
1
Q
Hypertension
A
- systolic BP > 140mmHg
- diastolic BP > 90mmHg
2
Q
The force exerted against the walls of arteries by the blood as it is pumped from the heart
A
Blood pressure
3
Q
Systolic BP
A
- highest pressure exerted
- ventricular contraction
- top number
4
Q
Diastolic BP
A
- lowest pressure exerted
- Relaxed ventricles
- bottom number
5
Q
The difference between the systolic & diastolic pressure
A
pulse pressure
6
Q
opposing forces to blood flow as the arterial channels become more distant from the heart
A
peripheral vascular resistance
7
Q
persistent elevated systemic blood pressure
A
Primary hypertension
8
Q
elevated blood pressure resulting from an identifiable underlying process.
A
Secondary hypertension
9
Q
Systolic pressure greater than 180mmHg and diastolic pressure higher than 120mmHg…
A
Hypertensive emergency
10
Q
Clinical manifestations of primary hypertension
A
headache - back of head,
usually asymptomatic
