- Anaesthesiologists exploring anaesthetic-related emissions
- Worth noticing
- It shows its calculation steps and cites IPCC AR6, DailyMed, NIST and UK government sources; it flags ongoing discussion around sevoflurane’s GWP100 value.
Field notes
The inputs cover agent, concentration, fresh gas flow and duration, with an optional annual case count. Results include agent consumption and a petrol-car distance comparison, while the methods section lays out the equations and constants used. The page cites IPCC AR6 for GWP100 values and identifies sevoflurane’s value as an area of scientific discussion. It explicitly says the tool provides no clinical guidance and that calculator entries are not stored.
