Image Number 2 for United States Patent #4665926.

In a system for respiratory feedback therapy, relaxation state can be qualitatively measured by forming a quotient between values related to the inhalation/exhalation duration and values related to the pause between inhalation/exhalation phases over intervals of 0.5 to 3 minutes or 5 to 20 respiration cycles.
