This procedure involves the dispatch of an ambulance to provide emergency medical care at the scene without transporting the patient to a hospital. The healthcare team assesses the patient, administers necessary treatments, and decides that the patient does not need hospital transport.

  • There are typically no preparations needed from the patient since this is an emergency response procedure.
  • The medical team may perform an initial assessment over the phone while en route to gather background information.
