The HSE National Ambulance Service (NAS) provides emergency pre-hospital care and emergency patient transport. When a 999 ambulance call is received, the caller is connected with the ambulance command and control centre for that area. The details of the call are recorded on a Computer Aided Dispatch System (CAD), with Advanced Medical Priority Dispatch (AMPDS).
The AMPDS system is designed to triage a call, so that the most appropriate resource is dispatched to the patient. The system allows an ambulance to be dispatched while the caller is still providing details of the patient's condition. The controller can also provide pre-arrival instructions to the caller, to allow initial medical assistance to be available and administered to the patient without delay.
In all cases, in line with the Pre-Hospital Emergency Care Council Emergency Priority Dispatch Standard, the nearest available ambulance is tasked to the highest priority incident. The highest priority incidents are ECHO (life-threatening cardiac emergency) and DELTA (life-threatening non-cardiac emergency). As the Deputy's query relates to service matters, it has been referred to the Health Service Executive for direct reply.
