Paramedics in emergency responses provide emergency care to sick, injured, and vulnerable persons in emergency medical situations, before and during transport to a medical facility. They implement and oversee the transfer of the patient in connection with transport. They provide assistance in acute situations, implement life-saving emergency measures, and monitor the performance of the transportation process. As allowed by national law they may also provide oxygen, certain drugs, the puncture of peripheral veins and infusion of crystalloid solutions and perform endotracheal intubation if needed for the immediate prevention of threats for the life or health of an emergency patient.
