Cautions

Contamination of samples with ambient air will drive the pO2 to equilibrate with ambient air (150 mmHg) leading to falsely low or falsely elevated results depending on the initial pO2 level; as well as falsely decrease the pCO2; and falsely increase the pH, which will also affect the portion of calcium bound to protein. Therefore, care should be taken to expel all air bubbles from all blood gas samples.

Syringes that are not completely filled will have increased heparin concentrations that can lead to erroneous measurements of pO2, pCO2, sodium, potassium, and ionized calcium.

Potassium results are elevated with in vitro hemolysis. Hemolysis is undetected in whole blood potassium measurements. Interpret results with caution.

Method Description

pO2, Glucose, Lactate: Amperometry

pH, pCO2, K, Na, ICA: Potentiometry

HCO3 GEM: Log (HCO₃ (c)) =   pH + log(pCO₂) – 7.608 mmol/L

HCT: 3.0 x tHb

COHGB: Co-oximetry; COHb% = 100 x (COHb/THb) %

MTHGB: Co-oximetry; MetHb% = 100 x (MetHb/THb) %

O2HGB: Co-oximetry; O2Hb% = 100 x (O2Hb/THb) %

Total HGB: Co-oximetry; THb = O2Hb + COb + MetHb + HHb

sO2: Co-oximetry; sO2 = 100 x O2Hb%/(O2Hb% + HHb%)

Base excess GEM: HCO3- - 24.8 + 16.2 x (pH - 7.4)
