Hypertension FINAL Flashcards
How to calculate MAP
SBP + (2xDBP)
then divide by 3
MAP is the mean (average) arterial pressure during a cardiac cycle. It is an indicator of
organ perfusion
> 60 mmHg is enough to sustain the organs of an avg. person
< 60 organs are not perfused and will eventually become ischemic
Strength of blood pushing against the sides of arteries. Influenced by cardiac output (CO) & systemic peripheral vascular resistance (PVR)
Blood pressure (BP)
Average BP that is higher than normal over a period of time consisting of two or more office visits
Hypertension
Indicates the health and tone of arterial walls
pulse pressure
High Blood Pressure is usually __________. Present for years without discovery, meanwhile doing damage to organs. AKA the “silent killer”
asymptomatic
Decrease in BP by 20 mmHg systolic and/or 10 mmHg diastolic
orthostatic hypotension
S3 heart sound
“Kentucky”, Ventricular Gallop, Normal in elderly, pregnant, and adolescent/athletes
ABNORMAL–> Systolic HF
S4 heart sound
“Tennessee”, Atrial Gallop, Almost ALWAYS pathological, Stiff Ventricle, diastolic dysfunction
ABNORMAL–> Left ventricular hypertrophy
Primary HTN
Chronic elevation in BP that occurs without disease. Can be diastolic, systolic, or both. Results in damage to vital organs & causes thickening of arterioles.
Secondary HTN
caused by underlying health problem
Nonmodifiable risk factors
- Age: develops 30-50yo
- Gender: Men <55, Women >55
- Ethnicity: African American
- Family Hx: Parent or Siblings w/HTN
Modifiable risk factors
- Obesity
- Stress
- Substance abuse
- Excess Na & water retention
- Elevated Lipids: Triglycerides and Cholesterol
- Sedentary Lifestyle
- Diabetes: blood vessel disease in HTN
- Diet: increased sat fats & salt –> plaque buildup
Diagnostics of HTN
-serial BP readings
-cholesterol levels
-microalbuminuria
Monitor for hypotension when using all HTN drugs
True or False
