compensated respiratory acidosis

Explanation:
Detailed explanation-1: -pH (7.35-7.45) PaO2 (75-100 mmHg) PaCO2 (35-45 mmHg) HCO3 (22-26 meq/L)
Detailed explanation-2: -If pH is normal but closer to the acidotic end, and both PaCO2 and HCO3 are elevated, the kidneys have compensated for a respiratory problem. If the pH is normal, but closer to the alkalotic end of the normal range, and both PaCO2 and HCO3 are elevated, the lungs have compensated for a metabolic problem (see Table 3).
