practical critical care capnography (video)

Waveform capnography has expanded in use over the past decade, but there is still a lack of broad understanding of its potential applications.

As part of the Cleveland Clinic Critical Care Medicine Fellowship conference series, I recently talked about the various uses and benefits of capnography for critically ill patients. The video is just over 20 minutes long and describes both respiratory and hemodynamic applications of this technology.

How are you using capnography?



  1. Matt,

    Thanks for this presentation.
    You’ve mentioned using mostly sidestream sensors in your unit. Are you using them with humidifiers on the circuit or with HMEs?
    Any specific reason you prefer the sidestream of the mainstream?



  2. Hi Yair,

    Thanks for the comment!

    At our main hospital we mainly use humidified circuits. In our regional hospitals we sometimes have HMEs, but they are relatively small (not the giant square ones). Practically speaking I don’t see much of a difference in the values/waveform.

    I wouldn’t say sidestream is a preference, rather than it just happens to be what we have available. The main downside in my estimation is the delay it takes the gas to reach the sensor, but practically this usually doesn’t mean much except for ETT confirmation (feels like it takes forever!).
