A medical emergency is a life threatening situation that requires immediate attention. Examples of a medical emergency include (but are not confined to) the following:

If you have a medical emergency on campus that requires an ambulance, dial the Emergency Campus helpline on 01 716 7999. They will call an ambulance and ensure that they are met upon their arrival on campus and are escorted to your exact location.
If you are off campus you should dial 112 and ask for an ambulance.

Urgent Medical situation (Non-Life threatening)
If you have an urgent health problem that is not life threatening your GP is your first port of call.
