Anaesthetic gas - monitoring practice and motivating change

Matthew Jenks's picture


Resource Description: 

I am an anaesthetist and recently visited the Centre for Sustainable Healthcare while on sabbatical. Thank you to Rachel and Frances for meeting with me. I have attached a copy of a behaviour change project i am undertaking in my anaesthetic department. Reporting on use of desflurane and sevoflurane and the potential to reduce greenhouse gas emissions by switching to sevoflurane (and save money). It is based on work done by Rob Burrell in Auckland (see link to talks at Sustainable Healthcare Aotearoa forum 2017 - Robs talk on his project is number 7). Rob has had a lot of success with this approach which i hope to replicate in Dunedin. If you have any questions please email me on

anaesthetic gases - tightening the feedback loop?

Thanks so much Matt,

VERY impressive CO2e reductions for a simple intervention - and rather large financial savings too, unless the NZ dollar is worth a lot less than i had realised!

Shows the importance of closing the feedback loop to maintaining and stimulating further behaviour change, that even a monthly email telling people about their department's anaesthetic gas usage can be so powerful. 

I have wondered previously whether it would be possible to produce a more immediate feedback, by displaying CO2e on the anaesthetic machine itself, as the gas flows are adjusted. Do you think this is feasible and has anyone tried it?
