Question

Ph=7.477, pCo2=23, pO2=72, HCO3=16.8....the patient has chronic renal failure whats that? from acid-base view?

Answer 1

From an acid-base point of view, you only need look at pH and pCO2. pO2 doesn't play, and HCO3 isn't measured.

What you have is an acute respiratory alkalosis superimposed on a chronic metabolic acidosis.

Answer 2

Chronic renal failure is kidney failure (renal = kidney)  You can tell the kidneys are failing because the HCO3 (bicarbonate level) is low.  This patient has what would be called uncompensated metabolic (meaning the kidneys are involved) alkalosis (the pH is above normal) with mild hypoxemia (low O2 concentration in the blood).  If this person is on a ventilator, the rate is too high causing them to blow off excess carbon Dioxide (CO2) and make the system more alkalai.  Decrease the rate and bump up the oxygen a little bit.  This will be somewhat more comfortable.  As for the kidney failure, that is doctor's preference in treating.
