Fully compensated state

List 4 and expected values for each

Fully vs. Partially compensated state

A

when the pH has returned to within the normal range, although other values may still be abnormal.

Respiratory Acidosis = pH

Respiratory Alkalosis = pH > 7.4, PaCO2 low, HCO3 low

Metabolic Acidosis = pH < 7.4 PaCO2 low, HCO3 low

Metabolic Alkalosis = pH > 7.4, PaCO2 high, HCO3 high

In compensated acid-base d/o, the pH will fall either on the low or high side of 7.4. Making note of where pH falls within the normal range is helpful in determining if the original acid-base d/o was acidosis or alkalosis.

Q

Partially Compensated State

A

when the pH has partially returned closer to the normal range, although other values may still be abnormal.

Respiratory Acidosis = pH < low, PaC02 high, HCO3 high

Respiratory Alkalosis = pH > high, PaCO2 low, HCO3 low

Metabolic Acidosis = pH < low, PaCO2 low, HCO3 low

Metabolic Alkalosis = pH > high, PaCO2 high, HCO3 high

In compensated acid-base d/o, the pH will fall either on the low or high side of 7.4. Making note of where pH falls within the normal range is helpful in determining if the original acid-base d/o was acidosis or alkalosis.
