Abstract
Summary: A random postal survey of 1528 anaesthetists in the UK was performed to assess their use of carbon dioxide in anaesthesia and opinion on its safety. Of 1100 replies (72% response rate), 60.9% used it daily and 77.1% would object to its exclusion from future anaesthetic machines. There was no consistent age‐related trend with regard to its use or opinion on its removal. 62.9% of anaesthetists did not regard its presence on the anaesthetic machine as hazardous, but 81.8% agreed that a limit to the maximum flow of carbon dioxide delivered to one litre/minute would improve safety.
