1. The Cardiovascular System

2. Structures The Heart Major Vessels The Spleen The Blood
Responsible for the flow of the blood
Carbon-dioxide rich blood to lungs for oxygenation
Oxygen-rich blood to vessels
Major Vessels
Arteries and Veins
The Spleen
Produces white blood cells
The Blood
Carries nutrients throughout body
Anemia = decrease in quantity or quality of blood cells

3. Heart Disease 900,000 lives are lost every year
Disease in the blood vessels decreases heart’s ability to perform
Many personal changes must be made after a Cardiac Disease diagnosis
Diet
Exercise
Sleep Habits

4. Heart Attack Myocardial Ischemia Treatment:
Deficient blood supply to the heart due to interference with circulation to the heart muscle
Treatment:
Complete bedrest
Check vitals often
Morphine and Oxygen given
After 3rd week can be discharged home (with no complications)

5. Congestive Heart Failure
Cor Pulmonale
Left sided failure- symptoms are in the respiratory tract
Cough, Fluid retained in lungs
Right sided failure- symptoms occur throughout body
Abdomen, chest, limbs swell due to fluid retention
Treatment:
Keep patient in upright position
Change position frequently
Never sleep on left side
Elastic stockings- channel blood to deeper vessels

6. Heart Block Interference with electrical control of the heartbeat.
Frequently caused by scarring from a previous heart attack
Treatment:
Pacemaker sends electrical impulses to regulate the heartbeat

7. Drugs Diuretics Cardiac Stimulants Helps flush excess fluids
Increases cardiac output but slows heart rate
Strengthens cardiac contractions
This acts as a diuretic

8. Hypertension High Blood Pressure Treatment: > 140/90
When blood pressure gets this high, risk for heart attack increases 200%
Treatment:
New Diet
Exercise
