Carbon Monoxide Poisoning

Horvath et al. Ambient CO and Maximal Exercise Rate Studies:

  • In most studies, young, healthy volunteers (2 studies used older volunteers) were exercised in various ways to maximal VO2.

  • There was demonstrated a linear relationship between decline in VO2 max. with increase in COHb.

  • Sub-maximal exercise for short durations (5-60 min.) is not affected by COHb as high as 15-20%.

    Figure 11. The effect of carbon monoxide exposure on time maximal exercise rate in healthy humans.
