*It is suggested to measure PVi in the same body position, remaining still and without talking, at the same breathing rate and depth of breathing, until you see a high confidence PVi value (displayed value is bright, not dim).  An increase in PVi may indicate a decreased level of hydration, increased breathing effort, or other factors.  A decrease in PVi may indicate an increased level of hydration, decreased breathing effort, or other factors.  Multiple factors other than hydration and breathing effort can affect PVi, including breathing rate, depth of breathing, body position, body movement, vascular tone, blood flow to the finger (perfusion index), normal variation within a short-term monitoring session, waveform shape changes, and/or cardiovascular abnormalities.
