An Emergency Medical Dispatcher (EMD) is a trained First Responder of sorts. They are the "first" EMS link that the caller encounters. Not all 911 telecommunicators are EMD-trained, but most 911 telecommunicators that dispatch EMS units are certified EMD, as well as other public safety doctrines (EFD for fire, EPD for law enforcement, etc.). Each part of the 911 telecommunicator's functions generally require a specific training class and credential.
EMD's are trained in providing pre-arrival instructions (how to perform CPR, stop bleeding, etc.) and post-dispatch instructions (gathering the patient's medications, putting away pets, sending someone to meet the ambulance, etc.).
