Baby bedroom directly over boiler room?

Imiller, thank you for what sounds like a spot on explanation; definitely something i won’t argue against.

for those who are wondering why i suggested any oxygen meter, i looked at the cost of genuine, professional level Co and Co2 meters and they were pricey; i was looking for something rolled into one. and they do seem to have air quality monitors out there that check at least some of these things. these are small things that can be set on the mantle or on the shelf in a babies room.

In a lab or industrial environment an oxygen deficiency sensor is sometimes used in areas where large quantities of cryogenic/liquified gas is handled, because significant leak could displace the oxygen in the environment. In these situations you are looking for a O2 drop of multiple %, and the ones I have worked with read out to 0.1%.
However, CO is toxic in much lower concentrations, so if you are trying to detect say 50ppm (0.005%) you are well below the typical resolution of an industrial oxygen sensor. Similarly the atmosphere contains about 0.04% CO2. If you are trying to detect say 1000ppm, that’s a change of 0.06%.
Furthermore, because nitrogen makes up most of the atmosphere, if you are using an O2 sensor you would only see a fraction (about 1/5) of the displaced amount as a change in the O2 reading, which works against you.
A typical resolution oxygen sensor isn’t going to provide much useful information if you are interested in detecting relatively sma ll concentrations of CO or CO2. Hopefully the numbers above are helpful in providing some context.
If I was trying to do this I would simply use sensor designed for CO or CO2.
