The general information of this guide is also applicable to both Exagon Sense and iMORE 2.0 Finger sensor as the hardware technology essentially is the same. To properly troubleshoot the Finger sensor, you need to first understand the working of the technology. iMORE is using photoplethysmogram (PPG) technology, that uses optically obtained plethysmogram to detect blood volume changes in the microvascular bed of tissue. It illuminates the skin and measures changes in light absorption. PPG reading used for Heart Rate Variability (HRV) runs at a much higher sampling rate as it needs to pick up every heartbeat and the differences in the millisecond range, as compared to general heartbeat monitoring sensor which they usually just take beats average or using extrapolation technique. The iMRS HRV assessment is based on per-minute interval. The system will evaluate the heartbeat variability within each minute window, and report a value between 1-7 as an indicative range of your HRV, so the iMRS system will use this value to adjust the session intensity accordingly. In general, people with higher HRV (higher value) means he/she has higher recovery potential, and hence is able to subject to higher exposure of external stimulation. If there are too many missing beats during the reading interval, the system may refuse to report a value for that specific interval, hence you will not see any value in the HRV chart for that interval. This section is applicable to iMRS system only Of course, there is a possibility of hardware sensor failure. Contact the nearest Swiss Bionic Solutions office for further support.
HRV Finger Sensor Troubleshooting Guide
Key reasons for intermittent and inaccurate reading are:
How to check your iMRS controller is configured correctly (applicable to iMRS system)
nc – when the iMORE is not physically plugged in
sc – when the iMORE is physically plugged in but not clipped on to a finger
heartbeat sign & rate – when the iMORE is clipped on to a finger
