Dental Arrest
Erin is at the dentist for a root cannel. She is pretty scared because this is her first time. The doctor gives her nitrous to relax her but needs to take a phone call. Erin has an adverse reaction to the gas and stops breathing. The doctor starts CPR on her right away. She administers oxygen via mask and gets the AED on her. She shocks her heart many times until she realizes she must phone 911.
