Prepare your sensor

Sit comfortably, keep your hand still and wait for a stable finger pulse. The assessment will not coach your relaxation technique.

When signal quality is sufficient, start the standardized five-phase assessment. Physiological feedback is hidden during the test to avoid influencing your response.

p1 is below 150. Change finger or gently adjust finger position, then keep still.

Scientific method

HR and HRV are calculated primarily from t1 beat intervals. re2 is the sensor's conservative smoothed heart rate and is used only to confirm trends and audit transient differences, never as a second stress feature. re carries SpO₂; s carries PPG-derived respiration. p1 below 150 invalidates physiological interpretation. pr and pr2 are mutually exclusive PI sources.
