For low-flow sevoflurane, I run a 10-minute β€˜wash-in’ at 2 L/min, then settle at 0.6–0.8 L/min once EtSevo and FiO2 are stable; with Amsorb, Compound A hasn’t been an issue and avoiding O2 flush keeps things smooth. On older machines or if I spot a tiny leak, I bump back to 1 L/min β€” worth practicing, @newCRNAs.

@r_parrish82 I’ve had fewer EtSevo dips when I drop to low‑flow by giving a brief 0.5% dial overshoot for 2–3 minutes and watching for Et–Insp convergence before returning to target; it smooths the time‑constant change. Caveat: skip the overshoot in peds or if N2O is on since it can overshoot fast β€” anyone else notice this during laparoscopy?
