Nathalia is in her gym class, when all of a sudden she feels her heart pounding, her gym teacher makes sure to send her to school nurse Aria. Nurse Aria checks Nathalia’s pulse and listens to her heart, and it is fast, but nothing to be concerned about. Nurse Aria attempts to relax Nathalia by allowing her to listen to her own heart, and then Nurse Aria’s heart. After handing the stethoscope back to Nurse Aria, Nathalia grabs her chest and collapses. Nurse Aria springs into action, laying Nathalia down and giving her compressions, along with mouth to mouth. She alternates this with listening to Nathalia’s heart with a stethoscope and her ear, as well as feeling her pulse, and completing sternum rubs. After 20 minutes straight of CPR, Nathalia coughs as she is brought back, and Nurse Aria leads her to the ambulance.
