What is the systematic approach to ABG interpretation?

Step 1: pH acidosis/alkalosis. Step 2: identify primary disorder (low PaCO2=resp alkalosis; high PaCO2=resp acidosis; low HCO3=met acidosis; high HCO3=met alkalosis). Step 3: check compensation. Step 4: calculate AG.

What is the Winter formula for respiratory compensation?

In metabolic acidosis: expected PaCO2 = 1.5 × HCO3 + 8 ± 2 (Winters formula). If actual PaCO2 higher, additional respiratory acidosis; if lower, additional respiratory alkalosis.

What compensation formulas are used for respiratory disorders?

Acute resp acidosis: HCO3 rises 1 per 10 PaCO2 rise. Chronic: rises 3.5. Acute resp alkalosis: HCO3 falls 2 per 10 PaCO2 fall. Chronic: falls 5.
