By the by; the use of 'Pan Pan Medico' in maritime transmissions is to enable shore based coastguards and port operations agencies to understand that you have a medical emergency requiring that a doctor is sought to talk to you in your language, or one common to you both. Unlike the aviation world there is no standard 'language of the sea.' There are many areas of the world where 'day no speakadee inglish, de chinese, de espagnol, de francais etc... So these words get the attention of the operator (hopefully) and he/she has a standard list of actions to get you the medical advice you require. This service is essential for ships that may be many hours (days!) from helecopter or lifeboat support.

I think that aviation has a different set of problems, mostly to do with time, but if the use of this call were internationally promulgated then there are situations were it could help expedite matters.
