Abstract :

Background–Arterial blood gas (ABG) is a gold standard to obtain information on the potential of hydrogen (pH), partial pressure of carbon dioxide (PCO2), partial pressure of oxygen (PO2), and bicarbonate (HCO3–) in order to measure the severity AECOPD. Objectives– to estimate PCO2, PO2, pH and HCO3– levels among patients of chronic respiratory illness with acute exacerbation. Materials and Methods– A cross–sectional survey was conducted in department of Respiratory Medicine of Nilratan Sircar Medical College and Hospital involving 49 eligible patients selected randomly. Data were collected via interview using a schedule and laboratory technique for arterial blood gas analysis. Results–Age of participants was 55.79�13.24 years. Exposure to smoke either from tobacco or cooking oven or inorganic dust was explored from 61% respondents. In present study blood level of pH, PCO2, PO2, and HCO3– were estimated to be 7.39�0.079 (mean�sd), 50.00 (median), 74.00 (median) and 28.2(median), respectively. Conclusion–ABG analysis is to be done systematically to choose effective treatment option required for each type of respiratory failure and to establish determinants of variation in ABG level among these patients.
