The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

Some physiological features of human respiratory tract important for establishing the adequate knowledge about the sources of the respiratory sounds are discussed. The understanding of peculiarities of such sound generation is necessary for creation of efficient computer systems for breath noise recording and processing intended for improvement of the respiratory diseases diagnostics. An essential multiparametric dependence of the respiratory sounds predetermines the necessity to document all these parameters in the process of measurements. One of the common parameters usually recorded in the process of measurement is the airflow rate measured with a pneumotachograph. On the basis of measuring the spread for the true glottis dimensions and estimation of the corresponding level of the respiration noise power spectrum we have shown that maintenance of predetermined airflow rate in different patients does not guarantee the same power levels of the respiratory sounds generated by airflow in the trachea.
