http://gsm.utmck.edu/surgery/documents/ABG.pdf WebNormal AG = 8-12 mEq/L with a serum albumin of 4g/dl. The normal AG depends on serum albumin. The expected "normal" range for AG can be calculated by 2.5 x albumin (g/dl) +/- 2. For severe hypoalbuminemia (2.0 g/dl), the expected gap would be 5 +/- 2, and an AG of 8-12 would be abnormally elevated. johnny cash sunday morning coming down lyricsWebElevated [HCO3] Hypocapnea Hyperkalemia Bicarbonate change for PaCO2 changes Hypoventilation: Expected bicarbonate elevation for chronic CO2retention (Renal compensation) is 0.35 x (current PaCO2-normal PaCO2) 0.35 x( 60-40)=0.35x20=7 meq/l Expected bicarbonate decrease for acute CO2retention (Buffering) is Hyperventilation: johnny cash sunday morning coming down chords
