Metabolic Vs Respiratory Acidosis/alkalosis- When To Tell What's Going On First?

So I was doing a practice passage from Kaplan and came across this passage discussing metabolic vs respiratory alkalosis/acidosis. I'm having a lot of trouble answering the questions requiring you to figure out how to determine which one occurs first based on the graph that came with the passage. You can eliminate A and C because point C is in an alkalotic state (is that even a word? Lol.) Point A is physiological pH, PCO2 and PHCO3. Look at the PCO2 levels at point C. This patient is in a state of hyperoxemia (too little CO2 in the body or too much O2 [aka hyperventilation]). The [HCO3-] is also at a basal rate, meaning this isn't a metabolic disorder, eliminating B. I am not sure whether I am looking at it right, but just using my own logic. Eliminate B, because in metabolic alkalosis the initial change is an increase in bicarb , and on the graph it clearly decreases. And it's D because from A to C, you have a decrease in CO2 which is an initial change plus you have a decrease in bicarb because it's a Continue reading >>
