Methods and systems for providing a breathing rate calibrated to a resonance breathing frequency
First Claim
1. A method for determining a first target respiration frequency for a user, the first target respiration frequency intended to improve a vagal tone of the user, the method comprising:
- providing the user with a first indication to breathe at a pre-determined respiration frequency for each of a first plurality of time periods, each of the first plurality of time periods having a pre-determined respiration frequency that is unique among the pre-determined respiration frequencies for the first plurality;
using a first sensor, taking first measurements of the user for each of the first plurality of time periods;
determining, from the first measurements taken of the user, a first heart rate variability value for each of the first plurality of time periods;
using a second sensor, taking second measurements of the user for each of the first plurality of time periods;
determining, from the second measurements taken of the user and the first measurements, a first respiratory sinus arrhythmia value for each of the first plurality of time periods;
combining in whole or in part, for each of the first plurality of time periods, the first heart rate variability value and the first respiratory sinus arrhythmia value to create a first vagal tone value for each of the first plurality of time periods;
comparing the created plurality of first vagal tone values to each other to determine a first optimal vagal tone value; and
setting a first target respiration frequency based on a first respiration frequency from a time period corresponding to the first optimal vagal tone value, the first respiration frequency selected from the first pre-determined respiration frequency or a first actual respiration frequency.

Abstract
A target respiration rate is determined for a user where, when the user breathes at the target rate, the user'"'"'s vagal tone is improved, which provides a physiological benefit to the user, e.g., stress reduction without drug intervention. The user is directed to breathe at different rates while heart rate and breathing rate are measured. A value representative of vagal tone is generated from the measured heart and breathing rates for each directed breathing rate. The breathing rate that produced the lowest generated vagal tone value is determined to be the user'"'"'s target respiration rate.
