Capnography, the monitoring of ETCO2 and the capnographic waveform is currently used in many areas of the hospital.
Understanding the clinical application of CO2 monitoring is important when utilizing this technology.
​This presentation will describe the various methods of CO2 monitoring and the physiology of ventilation-perfusion relationships.
- Understand the differences between a time capnogram and a volume capnogram

- Understand how capnography works

- Describe anaerobic vs aerobic metabolism

- Describe the physiology of gas exchange (Bohr effect, pH balance)

- Understand the clinical value of the capnography waveform

- Define the relationship between EtCO2 and RR

​- Discuss the advantages of mainstream vs. sidestream CO2 technology
