Abstract Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease with some significant extra-pulmonary effects that may contribute to the severity of the disease. Chronic obstructive pulmonary disease (COPD) is defined by progressive, irreversible airflow limitation with inflammatory response of the lung, usually to cigarette smoke. COPD involves several systemic features, particularly in patients with severe disease, which have a major impact on survival and comorbid diseases However, COPD is a heterogeneous disease in terms of clinical, physiological, and pathological presentation. The aim of the study is to investigate whether (BMI) and fat-free mass index (FFMI) could be related to parameters expressing airflow obstruction Severity. As regards the whole sample, there was a statistically significant positive (direct) correlation between FFMI between mild , moderate, sever and very sever COPD groups but As regards BMI there was no statistically significant difference between mild , moderate, sever and very sever COPD groups. Also there was no statistically significant difference between BMI and blood gas variables.(oxygen saturation,PO2,PCO2) in contrast to FFMI There was statistically significant decrease in oxygen saturation ,PO2with decrease in FFMI , and statistically significant increase in PCO2 with decrease in FFMI. |
