Immediately after signs of life are absent.
Start CPR on a child when no breathing and no pulse is confirmed.
If it's an adult, you should immediatly before CPR. If its a child, you should do CPR for 5 minutes and then call. It's approximately 2 Minutes for the infant or child. ~Jason, just passed his FirstAid/CPR Taining.
Yes; you should still do CPR.
You need to do 5 cycles of CPR in about 2 minutes. 2 breaths and 30 chest compressions constitutes a cycle. Chest compressions should be at a rate of about 100 compressions per minute - doing compressions in time to 'Nelly the Elephant' will be about the right speed.
Check for signs of life about every 2 minutes.
Each cycle of CPR should be performed in 24 seconds (30 compressions, 2 breaths). Therefore, in 2 minutes, 5 cycles of CPR should be performed.
Perform 5 cycles of CPR in 2 minutes.
Do a pulse check about every 2 minutes (or after 5 cycles of CPR).
The brain can survive for up to about six minutes after the heart stops. The reason to learn cardiopulmonary resuscitation (CPR) is that if CPR is started within six minutes of cardiac arrest, the brain may survive the lack of oxygen. After about six minutes without CPR, however, the brain begins to die.
In the initial assessment, check for signs of life. During rescue breathing, check for signs of life every 2 minutes. During CPR, don't check for signs of life any more. Unless you see obvious signs of life once CPR is started, continue doing CPR.

After a pulse check for 45 seconds, if no pulse exists commence with CPR.
