CPR NOTES
What does CPR stand for?
Cardiopulmonary Resuscitation
What is the first step of CPR?
Check the scene for Danger.
True or False: Hands need to be side by side pushing into the chest for successful CPR.
How should your hands be placed on the person to perform chest compressions?
Center of the chest with the fingers interlocked.
What is the name of the largest artery in your body?
The last thing the oxygen rich blood passes through in the heart.
Aorta Atery
When do you stop CPR?
• The scene becomes unsafe
• The victim shows obvious signs of life
• You become Exhausted
• Another trained rescuer arrives or takes
over
• You are too exhausted to continue
What is the second step of CPR?
Check for responsiveness/signs of life. Pulse, breathing, tapping, shouting.
True or False: You should lock your elbows when giving chest compressions
TRUE
True or False: Chest compressions are an optional step when performing CPR.
False: That is the entire point of CPR
If you diced a heart horizontally and were looking at the top piece, what are those two chambers called?
What is Cardiac Arrest?
When the heart stops or beats too ineffectively to push blood through the body.
After you have checked for signs of life what do you do then?
CALL 911 if life threatening
True or False. The depth of chest compression on an adult is 2 inches?
False! AT LEAST 2 inches
Where should you shift your body weight when you're performing CPR?
Over your hands. Lining up your shoulders over your hands.
When performing CPR, what muscle are you "mechanically' forcing to work?
The heart
What is a heart attack?
Blood flow to some parts of the heart is
compromised.
Why is it important that the body is on a hard surface when performing compressions?
For effective pressure/compressions it needs a hard surface to rebound off of. If the person is on a mattress it will be too soft and ineffective.
True or false: You should always send someone to retrieve an AED when you're performing CPR.
TRUE
True or False: When giving rescue breaths, no matter what you should always give two rescue breaths.
False. Rescue breaths are optional when performing CPR.
It is having to pump oxygenated blood out into the entire body.
Why can someone go from a heart attack into cardiac arrest, but not cardiac arrest to a heart attack?
A heart attack is a plumbing problem (blocked blood flow) that can lead to electrical problems (cardiac arrest), while cardiac arrest is primarily an electrical problem that stops blood flow
Describe the five steps of CPR in detail.
1. Check the scene for danger.
2. Shake and shout for responsiveness
3. Call 911.
4. Start CPR - 100/120 compressions per minute or 30:2 rescue breaths
5. Repeat if not awake, and wait for paramedics
Can you be sued for not performing CPR on a stranger?
No! Because of Good Samaritan laws. These laws protect individuals who provide emergency medical assistance in good faith from liability for negligence
Why is it important to act quickly and confidently during CPR, even if you're not sure you're doing it perfectly?
It is important in emergencies to act quickly and confidently. The role of bystanders in saving lives, and how doing something is often better than doing nothing
Describe the journey of blood flow throughout the heart.
Deoxygenated blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries to the lungs.
After picking up oxygen, the now oxygen rich blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
