Automatic Crash Notification Protocol Added to MPDS
The Automatic Crash Notification (ACN) Protocol for the Medical Priority Dispatch System™ (MPDS®) puts emergency medical dispatchers first in response for treating people injured in vehicular accidents.
Released as Protocol 34 in ProQA® for the MPDS, the protocol designed by the National Academies of Emergency Dispatch® (NAED™) handles two services that vehicle telematics systems typically offer: Automatic Crash Notifications and in-vehicle push-button calls (also called SOS or mayday push buttons).
When activated, the system automatically places a voice call to the Telematics Service Provider, or TSP, notifying them that a crash has occurred. If voice contact is made between the TSP and vehicle’s occupants, the TSP operator can conference in an EMD to relay Post-Dispatch and Pre-Arrival Instructions to the vehicle occupants.
If the caller’s answers suggest that the problem is not related to a traffic accident, ProQA prompts the calltaker to enter a more appropriate Chief Complaint and then shunts away from the ACN Protocol.
Automatic Crash Notifications may be triggered by airbag deployment, the seat belt tensioning system, or specialized collision detection sensors.
The use of Protocol 34 is an agency choice and not required for compliance to NAED standards. Due to several factors, including limitations of the MPDS cardsets, the ACN Protocol is available only in ProQA. MPDS cardset users should continue to apply Protocol 29, Traffic/Transportation Accidents, to process ACN-type calls.
