In cases where a 2-year-old patient is unresponsive, does not have a pulse, and does not have a history of heart problems, it is crucial to start CPR immediately. CPR helps to maintain blood flow and oxygen to the vital organs until professional medical assistance arrives.
The AED is an important device that can help restore the patient's normal heart rhythm by delivering a shock if necessary. However, CPR should be started before using the AED. It is recommended to first perform cycles of chest compressions and rescue breaths, and then follow the prompts of the AED if it advises a shock.
