A case about a kid that recently moved into a new home, and
she started to develop confusion , nausea vomiting , and a bunch of nonspecific
signs at least for me , note that the
question stem didn’t mention any thing about cyanosis , in fact O2 saturation
was normal !
I was suspicious about Toxicity, and I was right about that,
what I got wrong that my first investigation was a Tox screen , because according
to the question answer that ABG with specific request to measure
carboxy-hemoglobin and met-hemoglobin levels,
CO poisoning wouldn’t be associated with a drop in O2
saturation!
