Respiration Sensor (magnetic type) - MC-3MY

Our Respiration Sensor uses detects small movements in a stretch band. A small magnet is embedded in the stretch belt and a magnetic sensor detects the fluctuations in the magnetic field.
This is required for applications doing  RSA (Cardio-Respiratory Synchrony),  HRV and Breathing Work.
This is our most popular non-ECG cable . It is used in all EMG, HRV and even our EEG applications. It is not included with the purchase of an Instrument because some customers detect other signals and have no use for an expensive Respiration Sensor.

Respiration Line Graph

The respiration waveform displayed in a line graph has a 0-1000 scale used to depict the relative stretch of the respiration sensor belt. This signal may be displayed within in the following display formats:

1.      A single respiration waveform may appear in a single line graph.

This graph uses an autothreshold technique: A LONG AS THE SUBJECT INHALES, A TONE IS ENABLED. During exhale, the tone is off.

2.      Respiration signals may appear in a single line graph along with HR:

    This graph also uses an autothreshold technique: A LONG AS THE SUBJECT INHALES and HR is rising , A TONE IS ENABLED. During exhale or when HR does not match respiration, the tone is off.

A respiration signal may appear in combination with other types of signals as in the Breathing Pattern display below.


For those who prefer to do breathing training without a pacer, a single respiration  display is a good choice.

Breathing Pacer

Three different signals are displayed on this screen - a blue/orange breathing pacer, an aqua  respiration wave form, and a red heart rate variability wave form.

The effect of correct breathing can be easily observed as an increase in heart rate variability and an increase in synchrony between the HR waveform and the Respiration signal.  The HR signal can be hidden with the Show/Hide button if just the pacer and Respiration signal are desired.
