Acid-Base Question - Compensated respiratory alkalosis?
In compensated respiratory alkalosis, pH is normal and PCO2 levels are low. Are bicarbonate levels increased or decrease to compensate for the lower PCO2? Thank you.
Answers:
In fully compensated respiratory alkalosis;
pH returns to normal.
PaCO2 is still low usually due to hyperventilation
HCO3- is still low to correct the alkalosis
excretion of acid ions by the kidney is increased to minimize the effect on blood pH of excessive loss of carbon dioxide through the lungs, which occurs contained by hyperventilation.
Note: Thanks :) Whenever i have looked at ABG's Bicarb is usually there- not sure where you are or anything (not sure if it would be different contained by different countries etc) but thats just what i have found :) Source(s): Div 1 Nurse, i love looking at ABG's!
Good for HaLeZ. I'd point out that if you're looking at the ABG report, the bicarb level is NOT measured. Despite the long array of numbers that are printed stale, most machines measure pH, pCO2 and pO2. A few also measure carboxyhemoglobin. Those reassuring numbers approaching bicarb and base excess are calculated from the pH and pCO2, just like you could do on your own if you required to bother.
