Editing Cardiopulmonary resuscitation (section)

=== Exception to the main sequence ===

* If a rescuer is completely alone with a victim of drowning, or with a child who was already unconscious when the rescuer arrived, the rescuer should:
# First perform two minutes of [[Cardiopulmonary resuscitation#Compressions with rescue breaths|CPR maneuvers]].
#* Variation: when the lone rescuer does not have a phone, it is recommended to perform about two minutes of CPR maneuvers, and then go for a phone to call for emergency medical services<ref name=":1" />  (only if the rescuer can return in very few minutes to continue the CPR maneuvers, or emergency medical services will be with the patient in a few minutes).
# Call by phone for [[emergency medical services]]. Also, go for an automated defibrillator (AED), but only if the AED is available within a few minutes.
# [[CPR#Defibrillators|Attempt defibrillation]] with the automated external defibrillator (AED), because it is easy to use if it has been found. If not, or until it has arrived, attempt [[Cardiopulmonary resuscitation#Compressions with rescue breaths|CPR maneuvers]] as the latest step of those possible ones.

The reason is that CPR ventilation (rescue breaths) is considered the most important action for those victims. Cardiac arrest in drowning victims originates from a lack of oxygen, and a child would probably not suffer from cardiac diseases.<ref name=":2" />
