Further Inpatient Care

See the list below:

  • Admit patients who require resuscitation or oxygen supplementation.

  • For at least 12 hours, observe patients with likely diphosgene exposure who have minor symptoms or are asymptomatic, since delayed pulmonary edema is the classic feature of diphosgene exposure. However, one reference suggests that a minimum of 6 hours of observation is sufficient for a phosgene exposure. [1]

  • Counsel all patients with significant exposure to avoid strenuous activities for 72 hours and to return if significant respiratory symptoms develop.


Patient Education

Alert patients about returning to the emergency department or contacting 911 if they develop respiratory changes, such coughing, wheezing, or shortness of breath. For patient education information, see Chemical Warfare and Personal Protective Equipment.
