1. Blood Pressure Basics

2. Where the Heart is located

3. What is blood pressure?
The pressure that your blood exerts against your arteries as it is pumped through your body by the heart
The pressure in the arteries increases when the heart beats and decreases while it is resting

What is BP?

5. Measuring Blood Pressure
The Sphygmomanometer
The Sphygmomanometer is also called a Blood Pressure Cuff
Pump
Inflates the cuff to stop blood flow
Dial
Used to read blood pressure
Valve
Lets air out of the cuff, allowing it to deflate
Cuff
Used to temporarily stop blood flow

6. Measuring Blood Pressure
The Stethoscope
A stethoscope allows you to hear your heart beat and your blood flow
When used with a sphygmomanometer, you can hear the blood flow through your brachial artery, allowing you to measure your blood pressure

7. Measuring Blood Pressure
Procedure
Sit comfortably with arm supported at heart level
Snugly wrap the sphygmomanometer cuff around the upper arm, one inch above the elbow
Place the stethoscope just above the crease of the elbow
Pump the cuff to around mmHg
While listening with the stethoscope, slowly open the valve to let the pressure fall
When you first hear the beat of the blood flow, that is the systolic pressure
When you last hear the beat of the blood flow, that is the diastolic pressure

8. Reading Blood Pressure
Blood pressure is measured in mmHg, and given as a fraction
120 80
Systolic Pressure Pressure in the arteries while the heart beats
Diastolic Pressure Pressure in the arteries while the heart rests

9. Variations in Blood Pressure
Abnormally high blood pressure is called hypertension
Any blood pressure reading greater than is considered high.
Hypertension is usually asymptomatic .
Abnormally low blood pressure is called hypotension
There is not a specific blood pressure value that is considered ‘low.’
Symptoms define whether blood pressure is too low:
Dizziness
Blurred vision
Nausea
Fatigue

10. Blood pressure chart: What your reading means
Top number (systolic) in mm Hg
Bottom number (diastolic) in mm Hg
Your category*
Below 120
and Below 80
Normal blood pressure
Between
or Between 80-89
Prehypertension
Between
or Between 90-99
Stage 1 hypertension
160 or higher
or 100 or higher
Stage 2 hypertension

11. Blood Pressure
High Blood Pressure: Continuous elevation of blood pressure above the normal range.
Ex. 140/90

12. Hypertension Caused by both hereditary and behavioral factors
Diabetes
High-sodium diets
Smoking
Age
Genetic factors
There are usually no symptoms of high blood pressure, but the consequences of untreated hypertension can be severe:
Heart disease
Heart failure
Kidney failure
General heart/artery damage

13. Don’t Smoke or Use Smokeless Tobacco
Smoking traditional cigarettes, electronic cigarettes (e-cigarettes or vapes), or using smokeless tobacco (also called dip, snuff or chew) are some of the worst things you can do to your body.
Tobacco contains an addictive chemical called “nicotine” that gives smokers a pleasant feeling. Electronic cigarettes and “vapes” also deliver nicotine. Just because these products are high-tech doesn’t mean they’re safe.
Using ANY tobacco product damages nearly EVERY organ in your body and can cause heart disease and cancer.
Using smokeless tobacco is NOT a safe alternative to smoking!

14. Harmful Chemicals that can be found in Smoke or Smokeless Tobacco
There are thousands of chemicals found in cigarette smoke and smokeless tobacco that also found in other things:
Acetone — nail polish remover
Formaldehyde — embalming fluid
Hydrogen cyanide — insecticide
Lead — once used in paint
Nitrosamines — cancer- causing substances
Methanol — antifreeze
Cadmium — batteries
Arsenic— once used in rat poison
Hydrazine — rocket fuel
Propylene glycol – automobile anti-freeze
Toluene — paint thinner
Polonium 210 — toxic radioactive chemical
