Greener NHS Provides a road map for a future Net Zero.

The first production unit was introduced into a delivery suite at UHW, Cardiff mid-August and has been in regular use thereafter. Feedback from midwives was collected both informally and via questionnaire. Key takeaways:  Very positive and supportive of the project in terms of environmental benefit. Staff understand that Entonox is a greenhouse gas and that this machine reduces emissions. Many staff feel it will improve their health and wellbeing by reducing their own exposure to nitrous oxide. The machine was simple and easy to use It was quiet Although large, it was able to fit into the room ok It could be used with a mouthpiece or face mask depending on patient choice It did emit some heat, which although noticeable, didn't make the room uncomfortably hot

Implementing nitrous oxide cracking technology in the labour ward to reduce occupational exposure and environmental emissions: a quality improvement study.
