The survey has also revealed that a majority of the publications in this subject have been published as articles. The paper discusses the bibliometric analysis of the Digital Pulmonary Function Test from the Scopus database. The 405 archives extricated from this data set in the exploration region have been procured till 15th May 2021. It is the examination of the exploration distributed as articles, meeting papers, surveys, which helps in understanding the effect of the distribution on the specific theme worldwide. The representation is finished with open-source programming like VOS Viewer and Excel. The representation adds to a vastly improved understanding of the perspective in the specific research domain.
