A 40 years old male develops excessive hyperven-tilation. A G reveals pH- 7.5 pCO2 24 mm Hg PO2 88 mm of Hg. True statement is –
Correct Answer: Respiratory alkalosis
Description: First step
Determine whether it is acidosis or alkalosis
Increased pH indicates alkalosis
Second step
Inspect HCO3-/CO2 to determine the cause of alkalosis or acidosis.
pCO2 → 24 mm Hg (decreased)
The alteration in CO2 is in sync. with the alteration in the pH, so the alkalosis can be attributed to a decrease in pCO2.
Thus, it is a case of respiratory alkalosis.
