Stock Photo - 20 December 2021, Mecklenburg-Western Pomerania, Greifswald: View of the lights of the university hospital before the landing of the rescue helicopter ""Christoph 47"". The rescue helicopter ""Christoph 47"" is used when things have to move quickly within a radius of 70 kilometres. At night, the radius of action is even larger. Whether resuscitation on the beach of Usedom, traffic accident on the island of Rügen or respiratory distress in Barth - first and foremost, the helicopter brings the emergency doctor as quickly as possible to the scene or the patient quickly to the hospital.
