Age - risks increase with age, however, one in four deaths occur under age
Factors that can be changed:
Smoking one pack a day increases heart attack rate two times over a
nonsmoker and stroke rate five times over a nonsmoker.
Hypertension - (high blood pressure) is a major risk factor but with no
specific symptoms. One in three adults or 58,000 Americans have high blood
pressure controlled by diet, exercise and medications.
Diet - high fat, high cholesterol foods cause plaque to collect on artery
walls constricting blood flow.
Obesity - obese middle aged men have three times greater risk of heart
Lack of exercise - regular aerobics exercise at least three times a week.
Stress - A Type A personality, with a sense of urgency, drive and
competitiveness, has a greater risk.
The lungs function is to exchange carbon dioxide for oxygen.
Room air is 21 percent oxygen, exhaled air is 16 percent oxygen. We use only 5 percent. All body
organs and cells need oxygen to live.
During CPR, exhalation is due to normal relaxation of the chest.
The heart is the size of your fist with two separate halves (left and
right heart). The right heart receives blood from the body and pumps it
through the lungs back to the left heart. The left heart pumps fresh
oxygenated blood to all body parts.
The heart beats 60-100 times a minute, 100,000 times a day and pumps five
quarts of blood a minute or 1,800 gallons a day. Ninety percent of the time,
CPR will be done on a family member or close friend.
People do vomit and ribs do crack sometimes during CPR.
Never do blind finger sweeps in the mouth on anyone.
The victim should lie on a flat, hard surface.
If you are alone, do CPR for one minute, then call 9-1-1.
