Rescue breathing is typically used when a person is unconscious and not breathing adequately or at all, regardless of whether they have a pulse. If the person has a pulse but is not breathing, rescue breaths can help provide oxygen to their lungs. However, if there is no pulse, cardiopulmonary resuscitation (CPR) should be initiated, which includes chest compressions along with rescue breaths if trained to do so. Always prioritize calling emergency services in such situations.
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.
To check for a response from an unconscious person, start by gently tapping their shoulder and asking loudly, "Are you okay? Can you hear me?" If there is no response, try to assess their breathing and pulse. If they are not breathing or do not have a pulse, begin CPR and call for emergency medical assistance immediately.
If a person is unconscious and electrocution is suspected, first ensure the scene is safe and turn off the source of electricity if possible. Call emergency services immediately. Check the person's breathing and pulse; if they are not breathing or have no pulse, begin CPR. Do not touch the person until the source of electricity is completely turned off to avoid becoming a victim yourself.
For an Adult, if there are no signs of life, immediately go to CPR. For an Infant or Child, if there is no breathing, but a pulse start rescue breathing; 1 breath every 3 seconds.
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.
The rescuer at the head performs the rescue breathing and checks the pulse during compressions to confirm they are effective.
You would only administer CPR if the person does not have a pulse or (at a slightly lower place on the chest) if you knew/believed the person was choking. Otherwise, if the person has a pulse but is not breathing, you should administer rescue breaths.
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.
If there is a pulse, then perform rescue breathing only.
No. Monitor the pulse, and give rescue breathing if needed.
Agonal breathing will not support life; rescue breathing (or CPR if no pulse) is required.
That rate is not enough to sustain life. Rescue breathing must be started and if there becomes no pulse, CPR must be started.
