The following blood gas results were obtained from a child admitted to the ER 1 hour following 1 hour post-ingestion of an unlabeled unknown substance.
ABG RESULTS
pH: 8.1 (7.35 - 7.45)
HCO3: 27 (22 - 26 mmol/L)
pCO2: 30 (35 - 45)
What likely condition does the ABG indicate?
Which of the above parameters indicates the condition and why?
What common household drug can produce this effect?
How would the body compensate for this condition?
Homework Answers
* ABG finding indicate Metabolic alkalosis.
* Based on above ABG, elevation of PH level (8) ,Increase in bicarbonate level and decrease in pCO2
indicates metabolic acidosis because in this condition bases are added or acids are removed
excessively from the system due to metabolic changes of the body.
* Excessive use of calcium supplement drugs or antacids which contain calcium (calcium antacid
tablet) can produce this condition.
* In metabolic alkalosis bicarbonate and PH level increases so as a compensatory mechanism
depression in respiratory center which increases the pCO2 of blood thus increase H+ ion
concentration result in PH become normal.

13. A male patient, age 24, is admitted to the ER after an acute barbiturate overdose. Results from an arterial blood gas are as follows. Evaluate the information to determine respiratory or metabolic acidosis or alkalosis, and determine if compensation has occurred (2 points) Patient values: pH 7.29 HCO3- 25 mEq/L Pco2 70 mEq/L Po2 70 mm Hg Normal values: Arterial blood gases (ABGs): pH 7.35-7.45 Pco2 45-35 mm Hg Po2 80-100 mm Hg HCO3- 22-26 mEq/L
