1. A handheld portable biofeedback device for reducing stress in a human subject comprising:
- a housing;
a photoplethysmograph sensor disposed in the housing, wherein the photoplethysmograph sensor generates data from the human subject;
a control system coupled to the photoplethysmograph sensor; and
display screen,wherein the control system is configured to process the data from the human subject for output to the display screen, the output data providing the human subject with information associated with the human subject'"'"'s stress level; and
wherein the housing, photoplethysmograph sensor, control system and display screen form an integrated structure,wherein during respiration of the human subject said device is configured to record multiple heart rate related intervals of the human subject; and
analyze a portion of the multiple heart rate related intervals sufficient to delineate at least one individual respiratory sinus arrhythmia wave, andwherein the control system is further configured to determine a first value indicative of the human subject'"'"'s stress level by determining how far average wavelengths of the respiratory sinus arrhythmia wave deviate from a level that represents a relaxed state of the user.

Abstract
Easy to use, cost-effective methods and devices for evaluating and treating stress and thereby disorders caused or exacerbated by stress are provided. More particularly methods and devices for identifying RSA waves during respiration which provide a subject with near real-time RSA wave information are provided. This information can be used in biofeedback settings to assist subjects in reducing levels of stress by achieving rhythmic breathing patterns.
