Abstract

A biofeedback training method and apparatus to increase and reinforce the respiratory sinus arrhythmia as an outcome of a breath training technique, said apparatus comprising a physiological monitoring device that provides raw physiological data to a computer having a software program that receives and utilizes the heartbeat interbeat interval information supplied by the physiological sensors, calculates such intervals after every heartbeat, computes RSA parameters from the interbeat intervals, displays raw signal instantaneous heart rate values, calculates RSA parameters in the form of graphs, compares current values of the RSA training score with currently set threshold level to generate training feedback, provides continuous audiovisual feedback to the user to reward training attempts based on results of threshold comparisons, displays a breath pacer to induce an appropriate breathing pattern, recommended by selected breathing technique, saves interbeat intervals along with the RSA parameters into a built-in database for further review of training sessions, and permits the user to make several adjustments.

Dependent claims

An apparatus for monitoring respiratory sinus arrhythmia as a feedback tool in a breath training session, said apparatus having an operational mode and comprising:

a computer;
a visual display screen;
at least one physiological monitoring device selected from the group consisting of electrocardiogram (ECG) and photoplethysmograph (PPG) sensors for transmitting raw physiological data to said computer, said raw physiological data including interbeat interval data;
means for transmitting the raw physiological data from said physiological monitoring device to said computer;
a device driver for receiving the interbeat interval data along with raw physiological date signals from said at least one physiological monitoring device;
and
a software program installed on said computer that utilizes the interbeat interval information supplied by said physiological monitoring device and calculates such intervals after every heartbeat, and further performs the following operations:
(a) computes RSA parameters, including RSA Training Score and RSA Training Stability, from the interbeat intervals;
(b) visually displays raw signal instantaneous values of heart rate and calculated RSA parameters in the form of graphs;
(c) compares current values of the RSA Training Score with a currently set threshold level to generate training feedback;
(d) provides continuous audio-visual feedback to the user to reward training attempts based on results of threshold comparisons, said feedback including a least an RSA score;
and
(e) visually displays a breath pacer to induce an appropriate breathing pattern in the user as recommended by the selected breathing technique.
