I am a new LPN to RN nursing student and I am having a hard time with ABG's. Can anyone help me please. I have a case study with the following ABG...
pH 7.30, Pa0270, PC0247, HC0320mEq/L
I am interpreting this as Compined Respiratory and Metabolic Acidosis. Can anyone recheck my work please. Thanks so much!
Ok, let's look at what you have:
pH of 7.30- what does this indicate? Acidosis, right?
PCO2 47- what does this mean? CO2 is an acid with normal range of 35-45. So you have too much acid which produces an acidotic state.
HCO3 20- what does this mean? HCO3 is a base with a normal range of 22-26, so you have lost base which also gives you an acidotic state.
So, overall, I'd have to agree with you that you're looking at acidosis in both systems but I will admit that I am not too familiar with the real world implications of such a thing.
