Clinical and bioelectric characteristics determined by bioimpedance in patients with chronic obstructive pulmonary disease

Abstract

A descriptive and cross-sectional study of 99 patients with chronic obstructive pulmonary disease was carried out. They were assisted in the Pneumology Service "Dr. Juan Bruno Zayas Alfonso" TeachingGeneralHospitalin Santiago de Cuba, from February 1st to 15th, 2015 aimed at determining some compartments of body composition, according to the pattern of bicompartment organization of the human body and the method of the electric bioimpedance. In the series there was a prevalence of the male sex aged 50 to 69, and a higher frequency of III and II degrees (in that order) of the disease. On the other hand, malnutrition and muscular dysfunction were the 2 determining factors of clinical severity and prognosis of the disorder. Of the bioelectric parameters analyzed, the skeletal muscular mass was ratified as that of survival, morbidity and mortality; also the phase angle was demonstrated as bioimpedance parameter, mostly established for the clinical diagnosis and prognosis.
