ABSTRACT: Capnography allows us to measure the amount of expired (end tidal) carbon dioxide (CO2) and has become a vital monitoring tool when anaesthetising our veterinary patients. Knowledge and understanding of the information it provides is essential to the veterinary nurse (VN) anaesthetist.

This article provides a brief history of this technology’s development, the information capnography provides us, the varying waveforms commonly seen and how its use is an important contributor to the safety and stability of the anaesthetised patient. The waveforms encountered on the monitoring screen are also included and a brief description of what they may be demonstrating.
