Interpret the following arterial blood gas (ABG) result:

a. pH 7.48, HCO3– 12 mEq/L, PCO2 35 mm Hg, PO2 85 mm Hg

b. Name two treatments that may be used to correct this acid-base imbalance.

Answer 1

Normal pH is 7.35 - 7.45 . Here the pH value is 7.48 , so this is a condition of alkalosis,

Now we will check whether it is Respiratory or Metabolic origin. we can see that the bicrbonate level is decreased along with the CO 2 level and O2 level ,This is a Respiratory abnormality.

Intervention : Respiratory alkalosis

Treatment: Respratory alkalosis is not usually life threatening and the body often works to correct the imbalance, we can check the underlying condition and treat accordingly.

1. Opioid pain reliever or anti anxiety drugs to reduce hyperventilation

2. O2 therapy to help keep a person from hyperventilating
