Can someone help out me grasp blood gas?
I really need to know every thing. i spend a lot of time studying it and i'm still not competent to answer question on it.
areas to focus:
1. how do you determine weather it's metabolic or respiratory based on results of pH, PCO2, HCO?
2. how do you tell if it's compensated or not base on result of pH, PCO2, HCO?
3. can u help with anything else?
Answers:
pCO2 is the key to source if large then respiratiory acidosis if low then respiratory alkalosis.
pH if it is near or mundane it is compensated.

First, throw out the bicarb. It isn't measured, but only estimated from the pH and pCO2, which you can very well do yourself, if you're interested.
For adjectives intents and purposes, you can assume that there will never be over-compensation.
The first thing to do, obviously, is to see if the pH is above or below 7.40. Once you've arranged whether you're dealing with an acidosis or an alkalosis, the next step is to determine if it's metabolic or respiratory.
That's when you look at pCO2. Normal is 40. A drop of pCO2 to 30 should raise the pH by give or take a few 0.08. A rise of pCO2 to 50 should lower the pH by the same amount. That is, pCO2 and pH go in different directions.
And here's the trick that will keep you from ever again being confused: here is where you see what the pH "ought" to be if the pH adjust is purely respiratory. Anything else you see is, by default, metabolic.
