The Nitrous Oxide Project
Nitrous oxide alone contributes 2% of the total NHS England carbon footprint, and 75% of the total anaesthetic gas footprint. For the NHS to achieve net-zero emissions by 2040, the carbon impact of nitrous oxide products needs to be tackled.
Investigation by Alifia Chakera at NHS Lothian highlighted that a significant portion of nitrous oxide emissions are due to waste from manifolds and the associated piped infrastructure (1). The Nitrous Oxide Project is a way to centralise this work, promoting a lean methodology to identify system waste and improve medical gas management at acute sites. This project requires a multi-disciplinary team (MDT) approach, taking into account clinical use, product supply and total product turnover. Attached is an audit and analytics sheet to enable teams to investigate this easily.
