How effective in the CPR to a none breathing and no pulse patient?​

The chances are low of survival but are possible. It is effective if done properly and is in the right situation, such as: being in a hospital, having access to medications ad actual oxygen.

Explanation:

If there is no sign of breathing or pulse, begin CPR starting with compressions. If the patient definitely has a pulse but is not breathing adequately, provide ventilation without compressions. This is also called "rescue breathing." Adults: give 1 breath every 5 to 6 seconds. Reassess the pulse every 2 minutes.
