this is really just me being a bit nosy as to the biology behind whats going on. I was back in resus last night and my hospital apparantly does have a doc that understands that ABGs are more important that o2 probes, makes a change, and surprise surpirse my co2 was elevated. However, he was explaining to the nurse how to interpret the results and i was listening too, and he was talking about the fact that my pH was normal, and high co2 levels would lower my blood pH, and so that meant i was metabolically compensating. what does that mean? i assumed it would be something to do with the rate of respiration in my cells but i wasnt really sure.
plus, if my co2 was high but pH was normal, would that still explain why i felt really really sick, or is that likely to be die to something else, i think those two are linked, but im not really sure how!
finally, a quick side note, he described high co2 levels in an asthmatic as a 'pre-terminal' sign...that sounds really scary, but i didn't think i was THAT bad, i mean, dont get me wrong i'm not the sort to ring an ambu unless i'm really starting to struggle so i wasnt feeling particularily great, but i've felt worse, and i've felt worse and not had ABGs done - which is kind of more scary. is pre-terminal a poor choice of phrase (like terminal exams lol!) or is high co2 really that bad?
thanks for any info - i find this stuff really quite fascinating, and its always nice to be distracted from breathing by knowing cool stuff my body is trying to do to fix me!
