Abstract

Arterial blood gases are often measured as a part of respiratory assessment of obstructive lung diseases. Present study was aimed to study arterial blood gas analysis (ABG) in patients of Obstructive Airway Diseases in accordance with clinical correlation. Present study was single‐center, prospective, observational study, conducted in patients presenting first time with complaints of cough, breathlessness, chest tightness, wheezing and paroxysmal nocturnal dyspnea OR already diagnosed cases of Bronchial Asthma and COPD. Arterial blood gas analysis was done in all the patients. In overall study amongst 112 patients 74 (66.07 %) were males and 38 (33.92%) were females. Majority patients were from 35‐44 and 45‐54 years age group (27.67 % each). Amongst overall 112 patients, 63 (56.25%) were of COPD and 49 (43.75%) were of Asthma. Co2 washout (Paco2 <35 mm Hg) was seen in 29 (59.18 %) patients with Asthma, while Co2 retention (Paco2 >45 mm Hg) was seen in 8 (16.32%) patients, normal Paco2 was found in 12 (24.48 %) of the patients of Asthma. Hypoxia (PaO2 <80 mm Hg) was seen in 20 (40.81 %) patients of Asthma while 29(59.18%) patients had normal PaO2. pH was found to be increased(>7.45) in 28 (57.14%) patients, normal in 17 (34.69 %) patients and decreased (<7.35) in 4 (8.16%) patients of Asthma. Amongst patients with COPD 25 (39.68 %) patients had Co2 retention (>45 mm Hg), 21 (33.33 %) patients had normal Paco2 and 17 (26.98 %) patients had decreased (<35mmHg) Paco2. 52 (82.53 %) of the patients with COPD had hypoxia (PaO2 <80 mm Hg) and 11 (17.46%) patients had normal PaO2. Arterial blood gases are often measured as a part of respiratory assessment. PaO2 is positively correlated with FEV1 and Paco2 is negatively correlated with FEV1 in patients with COPD.
