The woman is lying in the helicopter and has been treated by an emergency physician. An intravenous therapy is on her left hand.

All Rega helicopters carry a crew of three: a pilot, an emergency physician, and a paramedic who is also trained to assist the pilot for radio communication, navigation, terrain/object avoidance, and winch operations. The name Rega was created by combining letters from the name "Swiss Air Rescue Guard" as it was written in German (Schweizerische Rettungsflugwacht), French (Garde Aérienne Suisse de Sauvetage), and Italian (Guardia Aerea Svizzera di Soccorso). Rega is a private, non-profit air rescue service that provides emergency medical assistance in Switzerland. Rega mainly assists with mountain rescues, though it will also operate in other terrains when needed, most notably during life-threatening emergencies. As a non-profit foundation, Rega does not receive financial assistance from any government.

Leonardo S.p.A is an Italian global high-tech company and one of the key players in aerospace. In close collaboration with the manufacturer, the Da Vinci has been specially designed to cater for Rega's particular requirements as regards carrying out operations in the mountains.
