Popis: Measurements of blood flow and ventilation per unit lung volume have been made by scanning the lung with scintillation counters after the intravenous injection or inhalation of the radioactive gas, xenon-133. The count rate at any level in the lung after display on a conventional recorder is laborious to read off and the calculations of blood flow per unit lung volume at each level are tedious. A data logger has been specially designed for parallel collection of these count rates on punch tape in a form acceptable for analysis by an Elliott 4100 computer. A detailed description of how information was presented to the data logger and examples of the punch tape output are given. A comparison of regional blood flow calculated by automated and non-automated methods is shown.
