On August 17, 2022 at 19:03, 9-1-1 Emergency Communications Specialist Browning received a 911 call for service; he determined the patient was unconscious and not breathing. He sent the call to dispatch so units could be started to the residence but remained on the line with the caller and started the Cardiac Arrest protocol and provided CPR instructions to the caller and another family member. He utilized the Compression monitor tool in ProQA to ensure compression rate and consistency while encouraging the caller to focus on the CPR instructions being provided until EMS arrived on the scene. Ambulance 159, Engine 152, Medic 17 and EMS 902 were dispatched to the incident in the New Market area for a cardiac arrest. The dispatcher reported CPR instructions were being provided to a family member on the scene and CPR was in progress. Ambulance 159 arrived on the scene to find the patients wife performing CPR. Engine 152's crew took over CPR while Ambulance 159's crew applied the AED. After receiving 9 minutes of CPR along with three shocks delivered from the AED the patient regained a pulse. The patient regained consciousness upon the arrival of Advanced Life Support who then started ALS care to include the administration of ALS medications. The patient was moved from the house to the ambulance using a Reeve's stretcher and ALS care continued while enroute to Frederick Health Hospital. The patient remained conscious and alert and care was turned over to FHH staff. The patient was discharged from the hospital on August 23, with no neurological deficit.
