When the patient gasps, there is a negative pressure in the chest, which not only sucks air into the lungs but also draws blood to refill the heart.
In contrast, mouth-to-mouth breathing creates overpressure in the chest and actually inhibits blood flow back to the heart.
Gasping during cardiac arrest is much better than mouth-to-mouth breathing. But what about choking? These individuals need the Heimlich maneuver. A primary cardiac arrest is the witnessed, unexpected collapse of an individual who is not responsive. Cardiac arrest will cause the stricken individual to pass out and collapse within seconds. Rarely, a patient with cardiac arrest will have a seizure. During cardiac arrest, blood flow stops. Technically, cardiac arrest means that the heart has stopped beating, but it's really assessed by the fact that blood flow is no longer detectable, even if the heart might still be trying to beat.
In both respiratory arrest and cardiac arrest , the patient will be unconscious and not be breathing. However, respiratory arrest patients still have a beating heart that is pushing blood around the body. Cardiac arrest patients do not. Without fancy equipment, the only way to tell if the blood has stopped flowing is to feel for a pulse. The way to feel that beating heart is through the blood pulsing through the arteries.
It's not a perfect procedure and there is a possibility of getting it wrong, even if you're a trained healthcare provider. Indeed, when the patient doesn't have a pulse, rescuers take longer trying to find it rather than treating the patient. As far as CPR is concerned, you should treat respiratory arrest and cardiac arrest exactly the same way: call and push on the chest.
These two conditions are absolutely linked. Respiratory arrest will always lead to cardiac arrest if nothing is done to treat it. Without treatment, respiratory arrest always leads to cardiac arrest.
Sometimes, however, it can take several minutes. Cardiac arrest means the heart is no longer moving blood through the body. It might be beating or not, but either way, there isn't any blood pulsing around. Without blood, the brain cannot survive.
A constant supply of fresh blood is required to keep the brain alive and functioning properly. When blood supply stops, the brain shuts down, including its respiratory center. So, when the heart stops, so does breathing, usually within a minute or less. Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life. Give 2 breaths after 30 chest compressions until the infant starts breathing or emergency medical services arrive.
It is best to be prepared in the event of an emergency. Look for classes offered by your local hospital, the American Heart Association, or the American Red Cross in your area or on the Internet.

First Aid: Rescue Breathing Rescue breathing is needed if a person collapses and stops breathing. A person may need rescue breathing in the following situations: Near drowning Overdose or poisoning Choking Carbon monoxide poisoning Severe asthma attack By breathing into another person's lungs rescue breathing , you can supply enough oxygen to preserve life.
In adults, call first and do the following: If the person is not breathing but has a pulse, give 1 rescue breath every 5 to 6 seconds or about 10 to 12 breaths per minute. Note: If you are alone, not trained in CPR, and a phone is nearby, call Protective face mask You may use a protective face mask. Follow the instructions that came with the mask.
