1ST STEP IN ABG

IS

MATCH pH TO EITHER CO2 OR HCO3

(DETERMINE IF ACID OR ALK THEN MATCH WITH EITHER METABOLIC OR RESP)

PARTIALLY COMPENSATED ABG HAVE A CHANGE IN

THE OPPOSITE SYSTEM, BUT STILL HAVE AN

ABNORMAL pH

ABG HAVE A CHANGE IN THE OPPOSITE SYSTEM

AND HAVE A NORMAL pH

ABG HAVE NO CHANGE IN OPPOSITE SYSTEM

(WILL HAVE EITHER NORMAL pCO2 OR HCO3 AND ABNORMAL VALUE WILL MATCH ABNORMAL pH
