Q

CO poisoning

A
  1. binds Hb w/ more affinity than O2, and reduces number of heme binding sites available to O2–> decrease O2 content in blood
  2. causes LEFT shift of Hb-O2 curve, reflecting decreased tendenccy of O2 to unload in tissues

**does NOT affect PaO2 (O2 dissolved in plasma) NORMAL
