title: The assessment of pulmonary vascular tone: a review of experimental methodologies.
abstract: Some of the difficulties inherent in studies of pulmonary vasoactivity are reviewed. We have outlined the various experimental approaches used to evaluate the effect of pharmacologic and other interventions on the pulmonary vascular bed, and have described the advantages and limitations of these techniques.
