How to interpret arterial blood gas results

WebMar 22, 2024 · Testing for HCO3 is usually done as part of arterial blood gas testing which determines whether the acid-base levels of the body are normal. Normal levels are pH 7.35-7.45, PaCO2 35-45 and HCO3 22-26. If the values for these measurements are outside the normal ranges, then the body has an acid-base imbalance. WebAnswer (1 of 4): pH is a property of a solution (or just solvent), it is not a property of a compound.
