The cuff should be supported near heart level for consistent technique.

Why it matters

An unsupported arm or a cuff far above or below heart level can make readings less comparable.

A practical routine

  1. Rest the forearm on a table or cushion.
  2. Relax the hand and shoulder.
  3. Use the same support height each session.

Make the record useful

Use a correctly fitted upper-arm cuff, sit quietly with supported posture, and record paired readings when recommended. Add short context notes when needed.
