Objectives: Arterial blood samples are the gold standard test but these are more difficult to get than venous samples. In this study we assessed the possibility of utilization of venous (peripheral and central) blood gas samples in evaluation of subjects with respiratory failure instead of arterial samples. Methods: critically ill subjects with respiratory failure had paired venous (peripheral and central) and arterial samples taken. Assessment of agreement between blood gas samples (arterial and venous) as regard PH, Pco2 and HCO3 was done using Bland–Altman analyses. The spearmen correlation and linear regression tests were also performed to assess the degree of association between arterial and venous samples. Results: 100subjects were included. A good agreement was found between venous (peripheral and central) and arterial values of pHand HCO3.The agreements between peripheral venous and arterial PH and HCO3 values is higher than agreements between arterial and central venous measures. Conclusions: venous blood gas analysis (mainly peripheral samples) could replace arterial blood gas analysis in the evaluation of acid base balance in subjects with respiratory failure

Bicarbonate (HCO3-) measurement in serum or plasma from a sample of venous blood is routinely practiced in hospital patient management. HCO3- status can also be assumed from Blood gas analysis requiring arterial blood as sample which is cumbersome for both patients and doctors. This study was undertaken to evaluate the extent of agreement among biocarbonate values obtained during venous, arterial blood gas analysis and conventionally measured serum bicarbonate levels in a group of intensive care unit (ICU) patients to determine whether conventionally measured serum HCO3- (from peripheral venous blood) and calculated HCO3-values (from arterial blood gas [ABG] analyzers) can be used interchangeably. A total of 51 adult patients with diverse medical conditions, presenting at a tertiary health centre ICU were enrolled in this study when deemed by the treating physician to have an ABG analysis. Arterial and venous samples were taken as close in time as possible for blood gas analysis and routine blood tests. Bland-Altman analyses were used to compare the three methods. The HCO3- levels from ABG, Venous Blood gas (VBG) and tconventionally measured serum HCO3- showed acceptably narrow 95% limits of agreement using the Bland-Altman method. VBG reveals higher level of agreement with the ABG bicarbonate values compared to measured serum HCO3-. Thus, venous blood can be an alternate for arterial blood where ABG analyzer is available. conventionaly serum HCO3- measurements can also be useful and used as substitute for an expensive ABG analyzer in resource constrained health care sectors when required.
