Title: Module 4
1Module 4
2Circulatory System
- The circulatory system consists of the heart and
a series of vessels that carry blood throughout
the body. -
3The vessels include
- Arteries carry blood rich in oxygen and other
materials away from the heart to the body cells. - Veins carry blood loaded with carbon dioxide and
other waste products from the body cells. - Capillaries are tiny vessels which connect
arteries and veins, as well as exchange oxygen
and waste products at the cellular level.
4 Risks Factors for Coronary Artery Disease
- Heredity
- Diet, high cholesterol and obesity
- Physical inactivity
- Age
- Smoking
- High blood pressure
- Gender
5Cardiovascular Problems
- Angina Pectoris
- A narrowing of an artery which diminishes the
blood supply to the heart. - Pain
- .
-
6Pain Progress
- Angina pain is usually relieved by rest
- Lasts three to eight minutes
- rarely longer than ten minutes
7Cause
- Brought on by
- stress
- overexertion,
- exercise
- a large meal
- The heart needs more oxygen than is available
8Symptoms
- pain in the chest
- Pain in arms
- or the neck
- not as severe as the pain of a heart attack
9Treatment
- Victims are usually aware of condition
- Have been given medication (nitroglycerine)
- Relieves the pain
- Dilates the blood vessels which increases the
flow of blood to the heart -
10Cardiovascular Problems
- High Blood Pressure (Hypertension) persons blood
pressure is significantly higher than normal. - It can cause damage to the heart, arteries, and
other vital organs.
11Statistics
- one in five Americans has high blood pressure.
- one-third to one-half are unaware they have
hypertension -
12Cardiovascular Problems
- Rheumatic Heart Disease caused by strep throat
rheumatic fever - Can cause permanent heart problems in children 5
to 15 years of age - .
13Damage
- Rheumatic fever can cause the opening through the
valve to become so narrow that blood flow is
difficult - This makes the heartbeat less effective
-
14Cardiovascular Problems
- Atherosclerosis-narrowing of the coronary
arteries - artery walls become narrowed or occluded
- blood flow to the heart muscle is reduced
- lead to eventual death of the heart muscle
15Heart Attack (Myocardial Infarction)
- The heart is a muscle,.
- when the heart is robbed of oxygen and nutrients
the victim has a heart attack. - The attack usually occurs in the left ventricle
which may be unable to pump or move all blood
coming from the lungs
16Pulmonary Edema
- Fluid accumulates in the lungs.
-
17Heart Attack Symptoms
- Severe pain
- It may travel from the left arm, to the neck, the
left side of the chest, the abdomen, or the back.
- Apprehension
- Sweating
- Shortness of breath
- Pale, cool, and clammy skin
- Nausea or vomiting
18 Treatment for cardiovascular disease
- Call 911
- Place the victim in a sitting position, leaning
forward. - Do not allow the victim to move.
- Comfort and reassure the victim.
- Loosen the victim's clothing and make him or her
comfortable. -
-
19Cardiopulmonary Resuscitation (CPR)
- Steps for Adult CPR
- Check area for safety
- Check for response Are you okay?
- Call 911.
- Open airway
- Check for signs of life
- If not breathing, pinch the nose and give two
rescue breaths - Recheck for signs of life
- Begin CPR 30 compressions to 2 breaths.
- Repeat CPR for 2 minutes (5 cycles) and check for
signs of life. - Continue until help arrives.
20Cardiopulmonary Resuscitation (CPR)
- Steps for Infant CPR
- Check for response by gently clapping hands and
tickling feet. - Open airway using head tilt-chin lift technique.
Be careful not to tilt the head too far back. - Check for signs of life for 10 seconds.
- If not breathing, cover infants nose and mouth
and give 2 rescue breaths. If the chest does not
rise and fall, reposition head and try again. - Begin CPR 30 compressions to 2 breaths.
- Repeat CPR for 2 minutes (5 cycles) and check for
signs of life. - Call 911.
21Good Samaritan Act
- A victim of cardiac arrest quite often is a
stranger and very often dies. The first responder
may worry about a lawsuit being filed. Today all
50 states have Good Samaritan laws and no person
has ever been successfully sued for performing
CPR..
22Guidelines for protecting a Good Samaritan are
- The rescuer is trying to help
- The actions are reasonable
- There is no compensation given
-
23AED- Automated External Defibrillators
- During cardiac arrest, the chaotic beating of the
heart (fibrillation) can be restored to normal
rhythm with an electric shock. - Electric shock is given by using an AED
(Automated External Defibrillator). - The shock paralyzes the heart, which may then
begin normal rhythm. If the AED is activated
within three minutes, survival increases
dramatically -
24AED- Automated External Defibrillators
- Guidelines for use of AED
- Call 911.
- Turn on AED.
- Apply pads to the patients bare and dry chest.
- Place one pad on the patients upper right chest
and the other pad on the patients lower left
side. - Plug the electrode cable into the AED.
- Follow prompts.
25 1. How Many Chest Compressions in a set?
26 2. How many sets of compressions should be
given followed by two breaths?
27 3. How long should each breath last when giving
CPR?
- 1. 1 second
- 2. 5 seconds
- 3. 3 seconds
- 4. 10 seconds
284. It is important when giving CPR to
- Push hard and fast
- 2. Give 302 compressions to breath ratio.
- 3. Release pressure on the chest after each
compression - 4. All of the above
29 5. When an infant needs CPR the first thing to
do is
- Begin compressions
- Call 9-1-1
- Obtain permission from parent
- Open airway and give breaths just like adult
protocol
30 6. Infant CPR ratio of compressions to
breaths is
31 7. Legally when giving CPR
- You must ask permission.
- You are protected by law
- If the victim dies you are liable.
- 4. All of the above.
32 8. AED pads are placed on a bare chest
- Side by side on the victims chest
- In the center of the chest and on the upper back
- On the victims upper right chest and lower left
side. - None of the above.
339. During use of an AED, if prompted to shock you
must
- Plug in the electrode cables.
- Turn on the AED.
- Give two breaths
- Loudly say Everyone stand clear.
3410. An AED should be activated within
- Three minutes
- Six minutes
- Ten minutes
- Twenty minutes.
