CPR
CPR, cardiopulmonary resuscitation, is a technique combining cycles of chest compressions and rescue breaths to oxygenate and circulate blood to maintain life. Ask and answer questions regarding the CPR techniques, training and history.

My most recent trainer told us to do one breath with every twenty compressions (pumps) for adults, and one with every ten pumps for children or other persons under 100lbs. If you have a smaller lung capacity, for any reason, change the above numbers to one breath per ten and five pumps, respectively.
What do you do when your using an aed and you feel a pulse?
Well nothing, if the pulse is present the AED will not shock the casualty unless the signal changes (or the pulse stops). Treat for shock and await EMS
When should a pre cordial thump be delivered?
A pre-cordial thump is delivered to a patient in cardiac arrest in an effort to counter ventricullar fibrillation and restart the heart. It should only be delivered if the cardiac arrest was witnessed AND a defibrillator is not immediately available.
What happens when you perform early CPR on a child in cardiac arrest?
Yes, once you have confirmed that someone does have a pulse and is not breathing (or breathing abnormally), you should immediately call emergency services and begin CPR until help arrives. Early CPR is essential in increasing the chance of survival of someone in cardiac arrest.
An adult should act with responsibility, demonstrating maturity and accountability in their decisions and actions. They should communicate effectively, showing respect and empathy towards others, while also maintaining healthy boundaries. Additionally, adults should strive for personal growth, balancing their obligations with self-care and pursuing their interests. Overall, being an adult involves embodying a sense of integrity and understanding the impact of one's behavior on themselves and those around them.
Why do you do chest compressions with the chest bare?
Exposing the chest gives you several advantages:
- It can reveal hidden injuries that you otherwise would have missed
- It facilitates attachment of the AED pads
- Exposing the chest makes it easier to find your hand position for compressions
- It makes it easier to monitor equal rise and fall of the chest during rescue breaths.
When do you contact 911 when giving an adult CPR?
Immediately. Contacting professional emergency services is the first step in emergencies requiring CPR. Have someone else contact them if others are present; do it yourself if others are not.
Is the primary cause of a child or infant passing out due to breathing or heart related problems?
It is breathing and respiratory problems. A child's airway does not fully develop until they are 8 years old. Most heart abnormalities are caught before birth and much more rare.
How many people to perform CPR?
It only takes 1 person to perform CPR. An advanced CPR course can be taken to train you on 2-person CPR, which makes it easier and more productive than 1 person CPR.
You should call 911 immediately but keep in mind that you only have about 4 minutes to get blood moving in the child's body before brain damage is a strong possibility.
If you found the child unresponsive and not breathing and are alone, give 2 minutes of care before making the call to 911.
What is the rate for performing chest compressions for an infant victim with one rescuer?
Perform chest compressions for an infant at a rate of at least 100/minute.
You must check adequate breathing before giving rescue breaths to an unresponsive adult victim?
Yes, if a person is already breathing there is no reason why you would need to breathe for them.
Why is it necessary to make sure the scene around you is safe before starting the ABC's of CPR?
Because if you become injured in an unsafe scene, you will be unable to help the victim AND will compound the problem by requiring assistance yourself.
Rescuers are often referred to as "first responders," which includes professionals like paramedics, firefighters, and police officers who are trained to provide immediate assistance in emergencies. In specific contexts, they may also be called "search and rescue teams" or "emergency responders." Additionally, volunteers or community members who assist in rescue efforts can be called "good Samaritans" or "volunteer rescuers."
What is the relation between compression ratio an torque?
The compression ratio in an engine refers to the ratio of the maximum to the minimum volume of the combustion chamber. Higher compression ratios typically lead to increased torque because they allow for more efficient combustion of the air-fuel mixture, resulting in greater energy release. However, excessively high compression ratios can lead to engine knocking. Therefore, there is a balance to be struck between compression ratio and torque output for optimal performance.
What is a AED?
An (AED) automated external defibrillator is a device that sends an electric shock to the heart that will restore the natural heart rhythm to the victim during a cardiac arrest.
When the AED electrodes are applied to the victim's chest, it automatically analyzes the heart rhythm and the rescuer is then advised whether a shock is needed to regain a normal heart beat. The heart has been defibrillated when the victim's heart resumes normal beating.
Our personal experience
My husband was sitting waiting to board a plane at LAX Airport, when a man walking in front of him collasped. A doctor sitting nearby ran over to see if he could help. The man was turning blue and was not breathing. From the expression on the doctor's face, it was evident that the man did not have a pulse. Airport personnel came running over with a defibrillator. They gave him two shocks from this machine and the man started breathing, got his color back and eventually he sat up.
My husband was totally blown away by what he had just experienced. This man in all intensive purposes was dead, but this small plastic box saved his life. I decided that this machine needs to be included in this website. Who knows it may save someone elses life.
When is a defibrillator used?
An automated defibrillator is used to treat ventricular defibrillation or sudden cardiac arrest (SCA). The AED machines make it possible for anyone to offer immediate help to a victim suffering from a cardiac arrest. A heart attack or other medical condition is when electrical signals in the lower chambers of the heart become uncoordinated, ineffective and the heart pumps little or no blood throughout the body.
Ventricular defibrillation can lead to cardiac arrest and the heart could stop beating altogether. Once in cardiac arrest, every minute that passes without defibrillation the survival rate decreases about 7 to 10 percent and then dropping to less than 50 percent.
Why can't we just call 9-1-1?
Emergency medical services may not be able to respond fast enough during a victim's cardiac arrest. They might have to deal with crowded urban areas, multiple story buildings, rural areas or large complexes. In fact the average response time nationally is between 10 to 12 minutes, so the best EMS responders may not arrive there in time.
The survival rate is only 5 in 100 SCA victims if defibrillation is not done early enough. More lives can be saved because of the very practical design of the AED's and the fact that most people are capable of using them. The more portable defibrillators that are put into public and private places, the better the chances for survival in SCA victims.

Place the links of the adult chain of survival in the correct order?
Cardiac Chain of Survival: 1) Early Recognition & Access; 2) Early CPR; 3) Early Defibrillation; 4) Early Advanced Medical Care.
How often should you stop and check for signs of life in a child while performing CPR?
Check for signs of life about every 2 minutes.
