A CROSS-SECTIONAL STUDY TO ASSESS THE ASSOCIATION OF VENOUS AND ARTERIAL BLOOD GASES (PH, PCO2 AND HCO3) IN COPD PATIENTS

Objective: Body acid base balance can best be determined through the analysis of arterial blood gas. It is also an important assessment tool for acid base balance verification in the human body. COPD (Chronic Obstructive Pulmonary Disease) is a disease that limit the airflow that cannot be reversed and causes failure of the respiration process. Our aim of this particular research was to determine the association between venous and arterial blood gases in the COPD patients. Material and Methods: The research is cross-sectional and it is completed in the Chest Medicine Department of Allied Hospital, Faisalabad (February 2017 to December 2017). A total of one hundred participants took part in the research. Every patient fulfilled the prescribed inclusion criteria. An informed consent was also secured before the commencement of research. Patients were drained for blood samples anaerobically from dorsal hand vein and radial artery with the help of two separate syringes. We analyzed the samples for pH, HCO3 and PCO2. Data analysis was made through SPSS software. Results: The outcomes reflected a patient’s mean age of (52.68 ± 10.51) years. There was a strong association between ABGs and VBGs as analyzed through pH, HCO3 and PCO2 which is r = 0.913, 0.994 and 0.999 respectively. A significant P-value was under 0.0001. Conclusion: There was a strong association of VBGs and ABG’s in COPD patients
