Differential Diagnosis

  • Phosgene is distinguished by its smell in high concentrations and delayed onset of pulmonary edema.
  • Chlorine has a characteristic odor even in low concentrations, immediate onset of respiratory distress, bronchospasm, eye, skin, and upper airway irritation.
  • Riot agents cause an acute onset of burning sensation in the eyes and upper airway without progression of symptoms. Riot agents do not cause laryngospasm except in high doses and patients never develop symptoms of peripheral pulmonary edema.
  • Nerve agents induce watery secretions as well as respiratory distress, but have a host of other symptoms, such as miosis, seizures, rapidity of onset, that can distinguish them from pulmonary agents.
  • The respiratory toxicity of vesicants (i.e. mustard) is usually delayed, but affects the central rather than the peripheral airway. Vesicant toxicity severe enough to cause dyspnea typically causes airway necrosis often with upper airway obstruction.
