title: [Interactive guided breathing technology].
abstract: OBJECTIVE
  Scientific guided breathing technology is to be studied based on the cardiopulmonary interaction.
  
  
  METHODS
  Heart rate variability was used as the target function to study the smoothly respiratory relaxation procedure in order to acquire the common pattern of regular and slow breathing.
  
  
  RESULTS
  Music based on the acquired common pattern was created and a musical pattern temporally-related to the breathing movement monitored by a sensor could be chosen to guide the breathing interactively.
