I’ve had a few outpatient procedures since starting on my CGM (Dexcom). I have explained to the “gas-man” what it is, what it does, and why I insist on keeping it on - with the receiver where the OR folks can here the alerts. Afterwards, every gas-person has said they thought it was cool, awesome and if it alerted, they did a fingerstick . I have yet to meet a gas-person who didn’t appreciate the help keeping track of my bg.
