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]
Hospital emergency codes Hospital emergency codes have often varied widely by location, even between hospitals in the same community. Confusion over these codes has led to the proposal for and sometimes adoption of standardized codes. In many American, Canadian, New Zealand and Australian hospitals, for example "code blue" indicates a patient has entered cardiac arrest, while "code red" indicates that a fire has broken out somewhere in the hospital facility.
