A patient is admitted with acute lung failure secondary to pneumonia.Arterial blood gas (ABG)values on the current ventilator settings are pH,7.37; PaCO₂,50 mm Hg; and HCO₃¯,27 mEq/L.What is the correct interpretation of the patient's ABG values?
A) Compensated respiratory acidosis
B) Compensated metabolic alkalosis
C) Uncompensated respiratory alkalosis
D) Uncompensated metabolic acidosis

Question

Quizplus · Accepted Answer

The ABG values reflect a compensated respiratory acidosis.Values include a pH of 7.35 to 7.39,PaCO₂ above 45 mm Hg,andHCO₃¯ above 26 mEq/L.Uncompensated respiratory alkalosis values include a pH below 7.35,PaCO₂ above 45 mm Hg,and HCO₃¯ of 22 to 26 mEq/L.Compensated metabolic alkalosis values include a pH of 7.41 to 7.45,PaCO₂ above 45 mm Hg,and HCO₃¯ above 26 mEq/L.Uncompensated metabolic acidosis values include a pH above 7.35,PaCO₂ of 35 to 45 mm Hg,andHCO₃¯ below 22 mEq/L.
