The aim is to study the relationship between arterial and venous blood gas measurements of pH, HCO3-& pCO2 in patients of non-respiratory diseases admitted in ICU in PCMS&RC, Bhopal.Enrollment of non-respiratory disease patients admitted in ICU reporting in our hospital to evaluate the relationship between arterial and venous blood gas parameters through Cross-sectional Study.The data we reviewed revealed us that venous blood gas analysis has the potential to be of great importance in the ICU setting in general as well as for patients presenting with different diagnosis. The association between Arterial and venous pH in which p-value of 0.85 which is not significant.The association between Arterial and venous pO2 in which the p-value of 0.001 which is highly significant.The association between Arterial and venous pCO2 in which p-value of 0.001 which is highly significant.The association between Arterial and venous HCO3- in which p-value of 0.056 which is not significant.Correlation between arterial and venous parameters reveals all the correlation coefficient (r) is positive and only pH, pCO2 and HCO3- are highly significant.The use of venous blood gas values has shown to be cost-effective and implementation of this procedure in the routine venous blood sampling will prove to be time and money saving as well, as it will reduce the risk factors for the patient and the health care worker. The venous blood gas values for pH and HCO3- showed excellent association and correlation and can be considered clinically interchangeable with arterial values.
