Aspirin Administration

by New York State
Emergency Medical Technicians
The New York State Emergency Medical Advisory Committee (SEMAC) and the NYS EMS Council (SEMSCo) have approved the EMT-B to administer aspirin (ASA) to those patients who are classified as cardiac related patients.
The American Heart Association 2005 Guidelines have stated that prehospital providers should administer aspirin to those patients who may be suffering from an acute coronary syndrome.

The NYS EMT-B Original Curriculum has been updated to reflect the change as well. In particular module 4-3 Cardiac Emergencies has been updated. The updated curriculum is available from the DOH web site at:
