why is red cross sign used by doctors and ambulances
Emblems of the International Red Cross and Red Crescent Movement In popular culture, the red cross symbol came to be a recognisable generic emblem for medicine, commonly associated with first aid, medical services, products, or professionals; it has been misused in toys, movies, and video games, outside its defined context. After objections from the Movement, derivatives and alternatives are used. Johnson & Johnson had registered the symbol for their medicinal products. The appropriation of the symbol has led to further confusion when first aid teams and ski patrols in the United States reverse the symbol–a white cross on a red background–thus suggesting an affiliation with Switzerland by simply re-applying the original idea of the red cross symbol, namely by reversing the red cross symbol's colors.[1][2][3][4]
Sign of the cross The movement is the tracing of the shape of a cross in the air or on one's own body, echoing the traditional shape of the cross of the Christian crucifixion narrative. There are two principal forms: one—three fingers, right to left—is exclusively used in the Eastern Orthodox Church, Church of the East and the Eastern Catholic Churches in the Byzantine, Assyrian and Chaldean traditions; the other—left to right to middle, other than three fingers—is the one used in the Latin (Catholic) Church, Anglicanism, Methodism, Presbyterianism, Lutheranism and Oriental Orthodoxy. The ritual is rare within other Christian traditions.
