  • Exposure in the presence of hypoxia, e.g. altitude above 1500 meters
  • Exposure during exercise, work
  • Simultaneous exposure to other toxic agents (CN, CO2, etc.)
  • Acute exposure of persons after chronically high COHb levels (?)

    In the Normal Individual:

  • Pregnancy
  • Life in Utero (fetal condition)
  • Old age
  • Male sex (?)
