What is CPR?
It is the artificial method of circulating blood and oxygen through a body and attempting to keep the brain alive. CPR does work. When initiated within four minutes, the survival rate is 43 percent. When initiated within four to eight minutes, the survival rate is ten percent.
Why Learn CPR?
- One in seven people will have the opportunity to use CPR in their lifetime.
- More than 650,000 people die annually from heart attack in the United States each year.
- More than 350,000 die before reaching the hospital.
- When the brain starts to go four to six minutes without oxygen, brain damage/death begins.
- On the average, it takes the Round Rock Fire Department about four minutes to respond to the scene of an incident.
- When CPR is needed, the Round Rock Fire Department is the first to initiate it 85 percent of the time.
- In the United States, there are 500,000 strokes a year.
- In the United States, there are 6,000 drowning incidents a year and 3,100 incidents of airway obstructions a year.
Certain individuals are more at risk for heart attacks or strokes because of genetic and lifestyle factors.
Factors that cannot be changed:
- Heredity — cannot change your genetic background
- Sex — women have lower incidents of heart attack
- Race — Blacks have a 45 percent greater chance of high blood pressure
- Age — risks increase with age, however, one in four deaths occur under age 65.
Factors that can be changed:
- Smoking — smoking one pack a day increases a person’s 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 attack.
- Lack of exercise – regular aerobics exercise at least three times a week can reduce the risk of heart attack or stroke.
- Stress – A Type A personality, with a sense of urgency, drive and competitiveness, has a greater risk of heart attack or stroke.
Signs and Symptoms of Heart Attack
- Chest pain – can be an uncomfortable pressure, tightness or feeling of indigestion, heavy squeezing pain like a weight on the chest, can radiate to left arm and neck
- Shortness of breath
- Pale, sweaty cold skin
- May have no signs or symptoms (silent Myocardial infarction)
Actions for survival
- Stop activity, rest, lay down
- If pain lasts more than two minutes, call for help
- Patient’s having early signs often deny having a heart attack
- Be prepared to do CPR, if alone do CPR for one minute, then call 9-1-1.
Four reasons to stop CPR
- Patient is revived
- You are relieved by another trained individual
- Become exhausted
- Doctor is present and pronounces death
There are steps that you can take to lessen the risk of heart attack or stroke before CPR becomes necessary.
- Avoid smoking
- Health diet (fiber, fruits, vegetables, avoid junk foods)
- Know and control blood pressure and cholesterol level
Facts about the respiratory system and CPR
- The lungs’ function is to exchange carbon dioxide for oxygen.
- Room air is 21 percent oxygen, exhaled air is 16 percent oxygen. 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.
