That means they are dead!!
Near death condition (or death).
When someone is not breathing and does not have a pulse
No, rescue breathing is not the same as CPR. CPR is rescue breathing and chest compressions. CPR cycles for an Adult is 30 compressions and 2 breaths.
The breathing rate and pulse rate are related proportionally. If the breathing rate increases, so does the pulse rate. The pulse rate is an indication of the breathing rate.
Give rescue breaths as agonal breathing will not support life.
Check for a pulse and breathing. No pulse, no breathing, give CPR.
For the condition of no breathing and no pulse, immediately commence CPR.
Check to see if they have a pulse, or are breathing. If they have both, no CPR is needed. If they have a pulse but aren't breathing, you can perform rescue breathing only without chest compressions. If they do not have a pulse and aren't breathing, you perform rescue breathing and chest compressions.
No. Monitor the pulse, and give rescue breathing if needed.
CPR.
Asphyxiation
Yes. You do CPR to mimic the action of the heart. If a person has a pulse it means their heart is pumping. If you give CPR to someone with no pulse, when their heart starts again they will typically vomit as a result of all the pushing on the chest. At that point stop and roll them on to their side so they dont choke. Edit: Dont confuse not breathing with a stopped heart. A person can have a pulse and still not be breathing. Think of being underwater. If you come across a person that is not breathing but has a pulse you need to open the airway. Lay them on their back, tilt the head backwards and open the jaw. Look for and clear any obstructions in their mouth.
First perform an Initial Assessment. Open the airway, Check for breathing, if there is no breathing give two rescue breaths. If the rescue breaths go in and make the chest clearly rise check for a pulse. IF there is no pulse begin CPR.
