Final answer:
After calling for help and ensuring the scene is safe, one should check for breathing and pulse and start CPR if necessary. Once the AED is ready, attach pads, follow prompts, and if required, deliver a shock while ensuring no one is in contact with the patient.
Step-by-step explanation:
After calling for help with an unresponsive female and determining that the scene is safe, the next step when you have an AED (Automated External Defibrillator) is to check the patient's breathing and pulse. If the patient is not breathing or only gasping and does not have a pulse,
you should begin CPR (cardiopulmonary resuscitation) immediately. This should consist of chest compressions and, if trained, rescue breaths. The CPR process helps to maintain vital blood flow to the brain and heart until the AED is set up and ready to use. Once the AED is ready, follow the machine's voice prompts to attach the pads and allow it to analyze the patient's heart rhythm. If the AED determines a shock is needed, it will direct you to deliver a shock. Always ensure no one is touching the patient during the shock delivery. It is crucial to follow the AED's instructions carefully throughout the process.
