CPR NOTES
What does CPR stand for?
Cardiopulmonary Resuscitation
What is the first step of CPR?
Check the scene for Danger - if it looks suspicious and like an emergency go ahead and call 911
True or False: Hands need to be side by side pushing into the chest for successful CPR.
What two "cava's" dump de-oxygenated blood into the Right atrium?
Superior and Inferior Vena Cava
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?
Move the body to a firm surface to work from.
True or False: You should lock your elbows when giving chest compressions
TRUE
If you were looking at a heart, how do you know what side is the right and what side is the left?
It is flipped from our rights/lefts.
Deoxygenated blood comes in on the right, oxygenated blood returns on the left.
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 (breathing,pulse,responsiveness) what do you do then?
If no sign of life- Begin compressions immediately
If there is a sign of life- still have 911 dispatched but just wait with victim until they pass out or medics arrive.
True or False. The depth of chest compression on an adult is 2 inches?
False! AT LEAST 2 inches
What kind of blood flows through the pulmonary valve? What's the name of the tube that pushes that blood to the lungs?
1. Deoxygenated Blood
2. Pulmonary Artery
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. A blockage in an artery but the heart is still trying to pump/work.
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
Why is the valve between the right atrium and right ventricle called "tricupsid"?
It has three flaps that help open/close to move blood
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 5 steps of CPR in detail.
1. Check the scene for danger & call 911 if it looks like an emergency.
2. Move person to a firm foundation
3. Check for breathing/signs of life
4. Start CPR - 100/120 compressions per minute
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
Explain why you can find pulmonary arteries and pulmonary veins on both sides of the heart:
Pulmonary Arteries and Pulmonary Veins both connect to the lungs which bring blood to and from the heart. Both sides of the lungs need artery/vein to attach to It.
Two Lungs= Two Sets of Tubes for each side
Describe the journey of blood flow throughout the heart.
1.Deoxygenated blood comes into the right atrium from the body through the superior and Inferior Vena Cava
2. moves into the right ventricle through the tricupsid valve
3.right Ventricle through the pulmonary valve, and out of the pulmonary artery to the lungs
4. After picking up oxygen, the now oxygen rich blood travels back to the heart through the pulmonary veins into the left atrium
5. It passes through the mitral valve into the left ventricle
6. from the left ventricle, through the aortic valve, then finally out to the body through the aorta.
