Fluid and Acidbase Help needed

Hi all:
My objective question asks that I interpret a patient's acidbase status, given normal values.
My text states "normal value" being 20/1 (HCO3/CO2) (based on Hendersonhasselbalch equation)....gawd!!!:imbar
Now talk about confusing.....
Can someone put it in layman's terms for me:
I do know the ph values for acidosis and alkalosis.
But since I have never seen a patient let alone their values (abnormal or not)....Can someone help me figure this out?
Thanks

Think in terms of what you would expect if the child was normal. What ranges would you expect to see on a blood gas, whether it was arterial or venous/capillary.
Now, what if the child has been crying for the past hour, what would you expect and why? What happens when they are crying? What happens if they hold their breath?
Think about these questions, then I will help you with the next step.......

Examples of acidotic states: respiratory depression (respiratory acidosis), constant diarrhea (metabolic acidosis  bowels are eliminating all of the bicarb. There is an easy way to remember this one, but will not post it here )
Examples of alkalotic states: anxiety/ panic (respiratory alkalosis  blowing off the CO2); nasogastric suctioning or vomiting (hypochloremic metabolic alkalosis).
