Tips for Using CorSense with Multiple Clients

The tips and instructions in this article also apply if you are using CorSense with your clients in a coaching or clinical setting: Can I Share a CorSense with Friends or Family?

A strong pulse and clean signal help CorSense more accurately detect and measure Heart Rate Variability (HRV). A weak signal results in CorSense taking longer to detect RR-intervals, or sometimes displaying very high or very low heartbeat numbers.

If you experience connection issues, the CorSense is likely having difficulty finding the pulse. Unlike with chest straps, there is huge anatomical variation in fingers - with sizes, shapes, skin colors, and underlying circulation patterns

CorSense hardware and algorithms try to address these millions of unique combinations. However, in some cases, the standard "Index finger" position may not work smoothly.

Here are examples to try: 

1. Seated in a chair
   • Hand resting still in lap
   • Palm facing up
   • Comfortable back position
2. Lying in bed (supine)
   • Hand resting gently on hip
   • Palm facing down
   • Arm still
3. Seated at a table
   • Sit back in chair
   • Do not lean weight on the table
   • Arm resting gently on table with neutral wrist position
   • Finger not pressing into table at all
4. Free standing
   • Weight evenly distributed in feet
   • Arm relaxed by side, neutral wrist, and relaxed hand
   • CorSense hanging from finger, not pressing against anything
