title: An index of cardiac output derived from the cardiopneumogram.
abstract: The cardiopneumogram has been reinvestigated as an index of stroke volume and cardiac output in anaesthetized dogs. Using a water-filled oesophageal balloon to calibrate the system good correlations have been found between the values derived from dye dilution and the indices obtained from the cardiopneumogram.
