In the nautical world there are strictly two types of Pan call. The Pan Pan which describes an Urgent situation, there is also a Pan Pan Medico call. This latter call is intended for those vessels where they require medical advice for an ill or injured person on board. These calls are routed via the jolly old CG to one of two hospitals where an on call doctor can provide treatment advice and/or will recommend evac or similar.
