A 24 year old graduate student was brought to the ED in a comatose state after being found unconsious in his room. A bottle of secobarbital was there on his bed stand. He did not respond to painful stimuli, his respiration was barely perceptible, and his pulse was weak. Blood gases were drawn and yielded the following results: pH = 7.10 pCO2 = 70 mm Hg pO2 = 58 mm Hg HCO3- = 20 mmol/L O2Hb = 80% (ref range, >95%) 1. What is the patients acid-base status? 2. What caused the profound hypoventilation? 3. Once the respiratory component returns to normal, what will be the patient's expected acid-base status?

Question
A 24 year old graduate student was brought to the ED in a comatose state after being found unconsious in his room. A bottle of secobarbital was there on his bed stand. He did not respond to painful stimuli, his respiration was barely perceptible, and his pulse was weak. Blood gases were drawn and yielded the following results:
pH = 7.10
pCO2 = 70 mm Hg
pO2 = 58 mm Hg
HCO3- = 20 mmol/L
O2Hb = 80% (ref range, >95%)
1. What is the patients acid-base status?
2. What caused the profound hypoventilation?
3. Once the respiratory component returns to normal, what will be the patient's expected acid-base status?
