Hyperbaric oxygen therapy (HBO2T) is a specialty with wide clinical applications and study fields. An evaluation of the major research direction of HBO2T studies would be helpful for researchers in this field. In this study, we identified the most frequently cited HBO2T articles to analyze the study focus of HBO2T research in the past 10 years. "Hyperbaric oxygen" was used as the keyword to search articles in PubMed between January 2000 and November 2010. The cited times of an article were tracked in Google Scholar. The top 100 most-cited articles were identified and their publication year, author nationalities, journal, study field and style were recorded and analyzed. In total, 2,362 HBO2T-related articles were retrieved. The number of HBO2T articles published per year has been increasing during the past 10 years. More than half of the top-cited articles (52/100) were from studies in the United States. Studies focusing on stroke (20), radiation injury (11), carbon monoxide (10), and wounds (9) accounted for 50% of the top-cited articles. HBO2T has been a field of increasing scientific publications in the past 10 years. The focus of research fields were stroke, radiation injury, carbon monoxide and wounds. The United States maintains an important influence on HBO2T studies.
