BP equation
BP = CO x SVR
Normal CO
4-8L/min
SVR (systemic vascular resistance) determined by?
blood viscosity, length of vessel, and diameter of vessel
MAP + normal range
average pressure in the arterial circulation through the cardiac cycle. (70-100)
MAP equation
(SBP + 2DBP)/3
Arteriosclerosis
hardening of vessels, usually due to plaque build-up
Hypertension
Based on 2 or more readings on separate occasions
SBP: 130 or higher
DBP: 80 or higher
htn risk factor for:
- Coronary artery disease
- Heart failure
- Renal failure
- Peripheral artery disease
- Stroke
- Retinopathy (damage to BV behind eye)
MODIFIABLE risk factors

, Nur 170-
Obesity, lifestyle, smoking, things you can change
NON-MODIFIABLE risk factors
genetics, age, gender, fam history, race (african-american ^ risk)
Vague symptoms
headaches in AM, fatigue, dizziness, flushing
Organ specific symptoms
Nocturia, confusion, N/V, chest pain, SOB, vision and retinal changes
Normal
<120 AND <80
Elevated
120-129 AND <80
Hypertension I
130-139 OR 80-89
Hypertension II
>/= 140 OR >/= 90
Primary Hypertension
"essential hypertension"
no known cause
90% of all cases
Secondary Hypertension
Identifiable underlying process (treatment focused on underlying cause)
5-10% of all cases
Tests
ECG, UA, Serum Creatinine, Vit D, Ca, Cholesterol, GFR (norm >60)
