Interpretive ranger Chuck Kokolskyj and protection rangers Tony Salvemini and Eric Tillson quickly arrived on scene and started CPR. Paramedic units from the Philadelphia Fire Department were summoned and arrived shortly thereafter. Tillson and the paramedics continued CPR while in transport to Jefferson Hospital. The patient finally responded to the CPR and was rushed to intensive care. He has since been moved to a private room for recovery.
