Pre-Hospital Triage of Mass Casualty Patients

Nerve Agents



Priority Description
Current State
Clinical Signs
  • Patients who require lifesaving care within a short period of time.
  • Emergency care must be available and of short duration
  • This care may include emergency measures that are performed within a few minutes time such as intubation or antidote administration
  • Unconscious
  • Talking but unable to walk
  • Moderate to severe effects of two or more organs or systems (i.e., respiratory, GI, etc.)
  • Seizing or post-ictal
  • Severe respiratory distress
  • Cardiac arrest (recovered)
  • Patients with severe injuries in need of major surgery, require hospitalization, or other care, but a delay in care will not adversely affect the outcome of this patient i.e. internal stabilization of a fracture.
  • Recovering from recent exposure or antidote administration
  • Diminished secretions
  • Improving or stable respiratory status
  • Patients who have minor injuries who can be helped by non-medical personnel and who won't require hospitalization
  • Walking and talking
  • Miosis
  • Rhinorrhea
  • Mild to moderate dyspnea
  • Patients with severe life threatening who probably would not survive even with the best of medical attention.
  • Patients with injuries that require attention from many medical personnel but low chance of survival does not justify the use of limited medical resources.
  • As this mass casualty event changes, these patients may be re-triaged once additional medical resources become available.
  • Unconscious
  • Cardiac arrest
  • Respiratory arrest
