   • The physiologist employed a kymograph to monitor the subject's respiratory patterns.
   • Using a kymograph, they recorded the rhythmic contractions of the heart muscle.
   • The stylus on the kymograph left a fine line on the rotating drum, representing blood pressure fluctuations.
   • Although largely replaced by digital monitors, the kymograph remains a symbol of early experimental physiology.
