Venous blood gas. A venous blood gas test is identical to an arterial blood gas measurement, except the blood is drawn from a venous site. This results in a slightly more acidic “normal” pH range. Most neonatologists use venous blood gas in neonates for metabolic evaluation and monitoring gas exchange, but not for monitoring oxygenation 1).

The venous pH tends to be more acidic than the arterial pH. Add 0.035 to the venous pH to estimate the arterial pH. In conditions such as DKA, it is probably reasonable to follow the pH response to treatment with VBGs.

The purpose of this course is to describe blood gas analysis, including the types of tests, expected results, sampling, nursing considerations, and acid-base imbalances. Goals Upon completion of this course, one should be able to do the following: • Describe normal range of values for at least 6 components of blood gas analysis.

? Venous blood gas analysis normal values Blood gas analysis (BGA) involves measuring three parameters: the amount of free oxygen (without output) (O2) and carbon dioxide (CO2) dissolved in the blood, and the pH (acidity/alkalinity) of the blood. The partial pressure (p) exercised by the two gases is what is actually measured so that the three Venous blood is good for HCO-3 estimation but bad for pH, pCO 2 and pO 2. While drawing venous sample make sure that no tourniquet is applied, artery is not compressed and sample is drawn against the flow of blood towards heart. Table I : Comparison of Blood Gas Analysis at different sites Arterial Capillary Venous All studies reveal a bias, with venous blood lactate tending to be higher than arterial blood lactate. The magnitude of this bias, however, varies significantly between studies, with mean difference (venous lactate – arterial lactate) ranging from 0.02 mmol/L in one study [12] to 1.06 mmol/L in another [20].

Its normal value is 40 mmHg at sea level, while it is 46.5 mmHg in venous blood. Increased values show respiratory acidosis, while decreased values demonstrate respiratory alkalosis. Alveolar-arterial oxygen gradient – p(A-a) O2 The 95% prediction interval of the bias for venous PCO2 is unacceptably wide, extending from -10.7 mmHg to +2.4 mmHg.
