Assessment:
         Relatively low concentrations of phosgene irritate the mucous membranes so initial symptoms will
         reflect:
            •  Tearing
            •  Runny nose
            •  Throat irritation

         If the patient is exposed to a higher concentration, airway and lung damage may also occur. How-
         ever symptoms of pulmonary edema will take several hours to develop. Thus a key point in treat-
         ment is realizing that the initially mild symptoms may lead to a serious condition within a few hours.
            NOTE: Exertion can worsen symptoms.


          Treatment of Pulmonary Agent Exposure
          Mild Symptoms
          •  Mild dyspnea                     Beta-agonist nebulizer (albuterol)
          •  Wheezing                         Oxygen
          •  Cough                            Rest
          Severe Symptoms
          •  Pulmonary edema                  Above plus,
          •  Severe dyspnea                   Airway management positive pressure
          •  Stridor                          ventilation
          •  Airway obstruction

         Riot Control Agents:
         Riot control agents include the common terms “tear gas” and “mace”. Specific agents include CS,
         CN, CA, CR and pepper spray (OC). Their common effect is intense irritation to the eyes, nose, and
         other mucous membranes. In the concentrations employed for field use, these agents are all con-
         sidered non-lethal. Under most field conditions, emergency care is limited to removal of the patient
         to fresh air. The effects of riot control agents are self-limited and no further treatment is usually
         needed. On occasion, a patient may experience severe shortness of breath and wheezing. This
         should be treated with a beta-2 agonist.


         Biological Agent Illnesses
         Biological weapons are living organisms or toxins produced by living organisms. They are deliber-
         ately used to cause disease in the target populations. Biological weapons are generally no different
         than naturally occurring disease except that they are concentrated and delivered with the intent to
         cause harm. There are about a dozen biological agents which are militarily significant. They can be
         roughly divided into four groups:
         1.  Pneumonia-like agents
         2.  Encephalitis-like agents
         3.  Biological toxins
         4.  Miscellaneous biological agents
