by Andrew. Yes, Cynthia. I realize who Florence Kendall isâand if you read the 6th paragraph, youâll see how I refer to âherâ book. You may then come to the conclusion that the âHeâ in the following paragraph is a typo and was meant to be âSheâ.
Overview & Description. This test is used to determine the amount of bicarbonate, called HCO3, in the blood. The test actually measures the blood level of carbon dioxide, called CO2. During laboratory testing, HCO3 is converted to CO2. HCO3 is important in neutralizing acids.he normal value for CO2 in the blood is 23 to 29 mEq/L. Most of the carbon dioxide in the blood is in the form of bicarbonate. Either term can be used.
A normal blood gas should be memorized using single values rather than a range: pH 7.40, pCO2 40, pO2 100, BE 0, HCO3 24. Our patient's arterial blood gas (ABG) shows that the partial pressure of oxygen (pO2) is slightly low, but satisfactory.BG-A is a normal blood gas in room air. ABG-B (pH 7.20, pCO2 60, pO2 70, bicarb 24, BE -3) shows a patient with acute respiratory failure. The pH is less than 7.40 which means that the patient has an acidosis.
