We added a rotating huddle timekeeper who opens each chart with “name–risk–one ask” and gives a soft “30-sec wrap” if it drifts; it keeps newer hygienists consistent without sounding scripted and protects the 8:15 start. If that feels too pushy, a silent sand timer works the same — would that fit your flow?

On overnights, I set the capnograph apnea alarm tighter (8–10 sec) and clip the sampling line to the ET tube with a mini hemostat so it doesn’t kink during turns. Caveat: condensation can fake a ‘low EtCO2,’ so swap the water trap first if the chest is moving fine. Building on @meganS78’s consistency point, we added a quick “EtCO2 trend?” check in our midnight huddle — the capno’s our night owl.

I zero the capnograph on room air while premeds settle and jot the patient’s baseline EtCO2 on the whiteboard so small drifts jump out before SpO2 changes. If condensation’s a menace, route the sampling line upward with a little drip loop and swap the water trap at the start of the shift; an HME can help too. As my mentor liked to say, “the capnogram tattles before the pulse ox even wakes up.”.

During 2 a.m. sedated rads, I run nasal cannula capno on non-intubated patients so the waveform flags hypoventilation before SpO2 budges. @meganS78’s tighter apnea alarm pairs well with this, but if they mouth-breathe or you’ve got high O2 flow, EtCO2 reads low, so I trust the shape — “shark fin” sends me to check positioning and the circuit first. , O2 washout can make the numbers lie.
