How does CO a ect us?
In high concentrations, CO can be fatal in minutes.
However, the e ects of lower concentrations over a
extended period of time can be just as lethal.
Our blood uses hemoglobin to carry the oxygen
we breathe to different body parts. Unfortunately,
hemoglobin carries CO more readily than it does oxygen.
e result is when we breathe in CO it replaces oxygen in
our blood and we begin to su ocate. Also, when we are
removed from the CO source it remains in our blood for
hours causing long term e ects. People have been known
to become sick and even lose consciousness hours a er
exposure.
