Outside the OR (IR and GI), I keep capnography front and center per standards, and I’ve been trialing a 6–8 mmHg delta alarm on Microstream to flag partial obstruction before SpO2 dips. What settings or strategies have reduced alarm fatigue for you while still maintaining airway safety?
‘6–8 mmHg delta’ on Microstream plus apnea at 12 s has cut my nuisance alarms in GI.
Alarm fatigue drives me nuts — biggest win was switching to the oral–nasal scoop cannula and keeping O2 ≤2 L/min; otherwise Microstream dilution makes your “6–8 mmHg delta” fire on mouth-breathers. I also set low RR at 6 with apnea at 15 s and bump high EtCO2 to 55 so I get one early warning instead of three overlapping chirps. @OP are you using the scoop style cannula in GI, or just nasal?
