What Does CPR Stand For?
Cardio = HEART
Pulmonary = LUNGS
Resuscitate = REVIVE
Cardio-Pulmonary Resuscitation = Reviving
the Heart and Lungs
Cardio = HEART
Your heart is a big, strong muscle that expands and
contracts more than 60 times a minute without you
even thinking about it. It is automatically driven by
electrical impulses and runs 24 hours a day, 7 days a
week, with no vacation time. That's around 33 million
beats a year!
Your heart has a simple, but important job. It pumps
oxygen-rich blood from the lungs out to the rest of
your body. If your heart stops pumping, oxygen does
not reach vital organs and they stop working. That's
when you get in trouble.
Pulmonary = LUNGS
*You breathe about 15 to 25 times each minute and every breath
you take brings oxygen into your lungs and gets rid of carbon
dioxide. Your lungs function automatically just like your heart - you
don't have to think about breathing, it just happens.
*Oxygen is important to your body because it gets combined with
sugar to burn as fuel. There is very little oxygen stored in your
body's tissues so it needs to be replenished often. (There is a big
supply of sugar so you can go a long time without eating.)
*If your body stops bringing air with oxygen in it into your lungs or
your heart stops circulating the oxygen-rich blood to your organs,
then bad things start to have real fast. When the oxygen runs out,
the body only has a few minutes before cells start to die and brain
damage results.
Typically, cells last 4 to 6 minutes before they begin to die and, after
10 minutes, the body is unrevivable.
Some things that might prevent oxygen
from reaching the cells of your
body:
Choking
- something blocks the path for air to reach the lungs.
Poisoning
- some other gas takes the place of oxygen, such as carbon monoxide.
Drowning or suffocation
- there is no air available to breathe in.
Electric shock
- an electric impulse disrupts the normal heart pattern and causes it to
stop.
Heart attack
- the heart stops beating. Oxygen is available in the blood in the lungs, but
the heart is not moving it around.
Ventricular Fibrillation (VF)
- the heart gets out of synch and quivers instead of pumps, causing cardiac
arrest. This is the most common cause of sudden cardiac arrest and is what
Automated External Defibrillators (AEDs) are for.
CardioPulmonary Resuscitation
(CPR):
is a combination of simulating the breathing of the
lungs and the pumping of the heart. You should know
that CPR is effective less than 30% of the time. Does
that mean it is useless? No way! The types of victims
you will probably run into will most likely be on the
high end of the probability scale. Recovery rates for
people already in the hospital are about half that and
less than 5% for elderly people with other medical
problems. So, even though there's a good chance your
efforts will fail, that person has a 0% chance if you do
nothing. Let's talk about what CPR is and how it works.
CPR is made up of two parts: Rescue
Breathing and Chest Compresssions
Rescue Breathing
You exhale air from your lungs into the victim's lungs so they can
absorb oxygen. When you breathe into a victim's mouth and have
their nose closed, the air is forced into their lungs and you can see
the chest rise. You have successfully gotten some amount of
oxygen into the system.
Chest Compressions
You manually compress the heart by pressing down on the chest.
When you let up on the chest, the heart expands. The hope is that
by compressing and expanding the heart, the blood flows through it
as designed. Unfortunately, you don't have an easy way to tell if
blood is flowing. You can't feel for a pulse or see results. You just
need to believe in your efforts.
CPR Effectiveness
When properly performed, CPR simulates from 20 to 40% of
normal circulation. That is not enough to sustain life indefinitely,
but will be sufficient to put off the start of cell death in the hope
that revival tools arrive soon. You should not expect CPR to
restart a heart and have the victim pop back to life like is shown
on TV. Your job is to keep oxygenated blood flowing until life
support services arrive.
In communities with a thorough CPR training program, CPR
can be effective up to half the time. Other places where CPR
training is not promoted, the results are much less. Remember,
your goal of administering CPR is to buy a little time for an
emergency rescue team to arrive and revive.
So, what does CPR stand for? It stands for saving a life.
ABC’s of CPR-Checklist
1. Check the Scene (make sure it is safe for you to help; don’t become
another victim)
2. Check the Victim (tap and shout to get response.)
3. Call for Help (call 9-1-1, or tell someone to call)
C. Circulation (pump the chest 30 times)
A. Airway (tilt head back, lift chin up to open airway)
B. Breathing (give 2 breaths; pinch nose closed, give breath until you see
the chest rise)
AED
Defibrillation (power on, place pads, plug in connector, shock if advised)
