  • Can be triggered by NSAIDs
  • Can be induced by physical mechanism like cold, vibration

Bradykinin Mediated

  • May progress slowly
  • Can be inherited or acquired
  • Common triggers include ACE inhibitors and TPA

Table 1 Differential Diagnosis

  • Protect airway
  • Epi, steroids, antihistamines
  • Avoid CPAP
