Agreed but I was wondering whether it was developing before it went out, as it improved at the surgery, then relapsed when back at home.

AFAIK pulse ox isn't accurate in CO poisoning as it overestimates the oxygen saturation

https://www.ncbi.nlm.nih.gov/pubmed/8037391

"Oxygen saturation as measured by pulse oximetry failed to decrease to less than 96% despite COHb levels as high as 44%. Regression between the pulse oximetry gap and COHb suggests that pulse oximetry overestimates O2Hb by the amount of COHb present. Pulse oximetry is unreliable in estimating O2Hb saturation in CO-exposed patients"

Any history of trauma? GI, respiratory or ocular dz? (Thinking along the lines of increased vagal tone?)

Did you get a blood pressure reading along with the bradycardia?

No signs of trauma at all and no, I didn't do bloodpressure (probably should have done!). He has almost completely recovered now, no more wobbliness, walking around, wagging tail, has eaten, still on fluids but probably going home tomorrow morning.

I have also been thinking of reasons of vagal stimulation, in combination with increased GGT (twice normal). But there have been no GI or hepatic signs otherwise.

Thanks! Something to consider. But pulsoxymetry measures were consistently 97-99% throughout the episode. Also difficult to think of a source of carbon monoxide in the garden?

Bright red gums, drowsy.. carbon monoxide?
