When a patient is choking, would this lead to an alkalosis or an acidosis situation?
Explain.
Calculate the pH of a blood plasma sample with a total CO₂ concentration of 25.7 mM and bicarbonate concentration of
24.4 mM. The relevant pK, of carbonic acid is 6.1.
Enter the answer with three significant figures.
