To make it easier for the lay person.
Do not stop CPR to check for a pulse.
CPR is used by First Aiders when someone has a heart attack and has no pulse, or when it is suspected that this is the case.
Cpr means
An infant in need of CPR will show no movement, breathing, or a pulse.
When performing a pulse check on an Infant or Child, check for a maximum of 10 seconds. For lay CPR, no pulse check is required for an adult.
You should use CPR if a person is not breathing (place your ear nearly to their nose/mouth, and look, listen, feel for warmth) and has no pulse (using you pointer finger, feel along the side of the neck for a carotid pulse).
CPR for the lay person, denoted just CPR, there is no longer a pulse check for an adult, so once CPR is started, it will be continued unless the person begins to show signs of life. In CPR-FPR (CPR for the Professional Rescuer) there is still a circulation check, so RB at 1 breath / 5 seconds is part of that certification. To specifically answer your question, most people would do CPR and not check for a pulse on an adult, because it is not part of the curriculum. For a professional person, they would perform rescue breathing with a pulse and CPR without a pulse.
USE CPR ON AN ADULT WHEN THEY ARE UNRESPONSIVE; ON A CHILD AND INFANT USE CPR WHEN THERE IS NO PULSE.

You do not perform CPR when there is excessive bleeding, you will effectively pump out the person's blood. Check for mass bleeding before CPR. Also, If the person has a pulse, there is no reason to perform CPR. If the person is breathing, speaking, or conscious. There is no need for CPR. CPR is used to pump the heart when it will not pump.
