Diagnosis and Clinical Significance of «Hidden» Spectral Disorders of Blood Oxygenation Among Smokers with Exacerbation of Bronchial Asthma

Abstract

The purpose of the study — to identify and evaluate the clinical significance of “hidden” disorders of blood oxygenation in smokers with exacerbation of bronchial asthma.Materials and methods: spirometry, pulse oximetry, CO-metry of exhaled air. To diagnose “hidden” disorders of blood oxygenation, including “hidden” violations of the spectral characteristics of the level of hemoglobin oxygen saturation, 19 male smokers (middle age 54,6±2,05 years) with exacerbation of mixed (68 %) or allergic (32 %) bronchial asthma were examined.The results: the accuracy of the clinical assessment of blood oxygenation in smokers increased significantly after the correction of the SpO2 level to the level of carboxyhemoglobin with the help of a computer program developed by us, which made it possible to diagnose a clinically significant lifethreatening exacerbation of this disease in smoking patients with bronchial asthma, since “hidden” respiratory insufficiency was detected in a timely manner.
