AY Honors/CPR/Answer Key

2. Know and understand the location and function of the heart and lungs.

The heart and lungs fill the upper chest cavity. The ribs and sternum form a cage that protects these vital organs. The heart is fairly central, with a lung on either side of it.

The lungs extract oxygen from inhaled air and inject it into the blood. The heart then pumps the oxygenated blood to the rest of the body. When a person performs CPR, the first task is to artificially fill the lungs with oxygen. This is done by rescue breathing. The second task is to move the oxygenated blood to the rest of the body - especially to the brain. This is accomplished by chest compresses (which squeeze the heart).

3. Define CPR and tell five conditions under which it would be used.

The chest compressions of CPR should only be performed if there is no pulse, but it is often dificult for non-professionals to sense the pulse. For this reason the current recommendations are that the non-professional should look for signs such as coughing, normal breathing, or movement. Checking for a pulse would waste valuable time in some circumstances. [math]\displaystyle{ _1 }[/math]

This may occur in:

Electrocution

Drowning

Heart Attack

Choking

Shock

The Heimlich Institute recommends performing the Heimlich Maneuver on drowning victims before performing CPR in order to get as much water as possible out of the lungs. [math]\displaystyle{ _2 }[/math]

4. Understand Prudent Heart Living. List five things a person can do to maintain a healthy heart.

There are a number of factors that can affect a person's heart health.

Smoking

Smoking raises your risk of a heart attack by two to six times. In the United states 20% of all cardiovascular disease is related to Smoking. The best advice is don't smoke.

Diet

Heart healthy diet- A well balanced diet can improve your heart health. You should eat more , fruits (especially those high in vitamin C), nuts, and vegetables,especially leafy vegetables. Increase your intake of omega 3 fatty acids by eating flax, leafy vegetables, or fish and use olive oils rather than other "bad fats".

Heart damaging diet- A diet rich in saturated fat, trans-fats, cholesterol, sugar and salt can damage your heart or blood vessels. Cholesterol is found only in animal products, and saturated fat is found in great quatities in meat, milk products, and eggs. Greasy or fried foods especially the modern "Fast Food" diet is very bad for your health.

In Britain 50% of all death is from heart disease, but death from heart disease was found to be 28% less in vegetarians. Adventist's are known for their health message, but over the years, fewer and fewer people have adopted the health principles of the church, and there has been a noticeable increase in heart disease within the church.[math]\displaystyle{ _4 }[/math]

Exercise

Regular aerobic excercise keeps your heart which is a large muscle in good condition.

Drink plenty of water

To determine how much water you should drink to stay hydrated, take your body weight in pounds, divide it by two, this is the number of ounces of water you should drink each day.The Adventist Health study found that those that drank 2 glasses a water a day had about 3 times more deaths from heart disease than those that drank 5 or more glasses a day.[math]\displaystyle{ _5 }[/math]

Stress

Stress raises your risk of heart problems.

Heredity

There is not much that you can do about your genetics, but you may have inherited heart properties that are good or bad.

Gender

Men tend to have more heart disease than women although there has been some equilization in recent years as more women have started smoking.
