Association of Low body Mass Index with Respiratory Failure in Chronic Obstructive Pulmunary Disease

Various studies have shown that low body mass index co-relates with the severity of Chronic obstructive pulmonary disease. The reduced body mass index in these patients is thought to be due to nutritional abnormality and raised circulating inflammatory markers. The study is aimed to find the association of body mass index with respiratory failure in patient with chronic obstructive pulmunory disease. 142 patients who attended emergency /out-patient-department in Sir Sundarlal Hospital from August 2018 to July 2020 were enrolled for the study. 81 patients in one group had chronic obstructive pulmonary disease exacerbation with Type II respiratory failure. Among this group low and normal body mass index subgroup was categorized.61 patients in another group had chronic obstructive pulmonary disease. Non-invasive ventilation was applied to case group. Categorization of body mass index was done
