Hypertension
• What is Blood Pressure?– Pressure created by the heart as it pumps
blood through the arteries and the circulatory system
• What do Blood Pressure Numbers Mean?– Top number (Systolic)= Pressure while heart is
beating– Bottom number (Diastolic)= Pressure while
heart is resting between beats

Hypertension
• Normal Blood Pressure– Blood Pressure of < 140/ 90– Blood Pressure of 130 to 139/ 85 to 89 should
be closely watched
• High Blood Pressure– Blood Pressure > 140/ 90

Hypertension
• How can I tell if I have High Blood Pressure?– Usually NO SYMPTOMS!– “The Silent Killer”–May have: • Headache• Blurry vision• Chest Pain• Frequent urination at night

Hypertension
• Blood Pressure Measurement– Sphygmomanometer– Systolic pressure= pressure when 1st sound is
heard– “Diastolic pressure= pressure when last sound
is heard
• Blood Pressure Cuff Size– Small – children and small adults– Average– Large – overweight and large adults

Hypertension
• What Causes High Blood Pressure?– Cause unknown in 90 to 95% of cases =
Primary Hypertension– Secondary Hypertension = 5 to 10%• Kidney Abnormalities• Narrowing of certain arteries• Rare tumors• Adrenal gland abnormalities• Pregnancy

Hypertension
• How does High Blood Pressure develop?– Certain nerve impulses cause arteries to
become larger (dilate) or smaller (contract)
– If vessels wide open blood flows easily
– If vessel narrows pressure inside increases causing hypertension

Hypertension
• What does High Blood Pressure do to my Body?– Stroke– Congestive heart failure– Kidney failure– Heart attack– Heart rhythm problems– Aneurysm

Hypertension
• What Can I Do?– High blood pressure is a lifelong
disease– Blood pressure can be controlled not
cured– Controlling blood pressure will reduce
the risk of stroke, heart attack, heart failure and kidney disease

Hypertension
• Medication for High Blood Pressure– Diuretics• Rid the body of excess fluids and salt
– Beta-blockers• Reduce the heart rate and the work of the
heart
– Calcium antagonists• Reduce heart rate and relax blood vessels

Hypertension
• Medication for High Blood Pressure– Angiotensin II receptor blockers(ACE)• Interfere with the bodies production of
angiotensin, a chemical that causes the arteries to constrict (narrow)
– Vasodialators• Cause the muscle in the wall of the blood
vessels to relax, allowing the vessel to dialate (widen)

Hypertension
• Medication for High Blood Pressure– Sympathetic nerve inhibitors• Sympathetic nerves go from the brain to all
parts of the body, including the arteries• Cause arteries to constrict raising blood
pressure• These drugs reduce blood pressure by
inhibiting these nerves from constricting blood vessels

Hypertension
• Home Blood Pressure Monitoring–Mercury sphygmomanometer• Standard for BP monitoring• No calibration• May be bulky• Need a second person to use machine• May be difficult for hearing impaired or
patients with arthritis

Hypertension
• Home Blood Pressure Monitoring– Aneroid equipment• Inexpensive, lightweight and portable• Two person operation/need stethoscope• Delicate mechanism, easily damaged• Needs calibration with mercury

Hypertension
• Home Blood Pressure Monitoring– Automatic equipment• Contained in one unit• Portable with easy-to-read digital display• Expensive, fragile• Must be calibrated• Requires careful cuff placement
