Informative, straightforward article on capnography:

5 things to know about capnography

See if you can reason this out.

1) What IS etCO2? What is it measuring? Where does that CO2 come from, and what path does it take to get from the blood to the monitor?

2) What causes exhaled CO2 to increase? Decrease? Do we care about any of those things?

3) Do we specifically care about any of those things in people who are sedated? Why?

After you read that great little article, answer all three of these and you'll always know.
