Each year a highlight of the Annual Meeting of the American Association for Respiratory Care, the RESPIRATORY CARE OPEN FORUM, provides a platform for the reporting and discussion of some of the clinical studies, methods and device evaluations, and case reports completed by members and friends during the previous year. During the 1992 OPEN FORUM in San Antonio, Texas, December 12-15, more than 120 papers will be presented- clustered into 12 minisymposia. The abstracts of those papers are published here, sequenced as they will be presented. An index of the authors appears on page 1372, with Presenters designated by boldface type.
