Operating Instructions

Correct Measurement Posture

Maintaining the correct posture is crucial for accurate blood pressure readings. Incorrect posture can lead to inaccurate results.

Image: Illustration of the correct measurement posture: sitting with feet flat on the floor, back supported, relaxed, palm facing up, elbow on a table, and a towel under the wrist to ensure the cuff is at heart level.

• Sit on a chair with both feet flat on the floor.
• Rest your back against the chair backrest and relax.
• Place your left palm facing upwards and rest your elbow on a table or stand.
• Place a towel or cushion under your wrist to ensure the cuff is at the same height as your heart.

Measurement Precautions

Pay close attention to the following points to ensure accurate readings:

Image: Visual warnings against common measurement errors: cuff position too low or too high relative to the heart, applying force to the hand, and bending the wrist during measurement.

• Cuff Position Relative to Heart:
  • If the measurement position is higher than the heart, the measured value tends to be lower.
  • If the measurement position is lower than the heart, the measured value tends to be higher.
  • For accurate measurement, always align the cuff position with the height of your heart.
• Wrist and Hand Position:
  • Do not apply force to your hand or wrist.
  • Ensure your wrist is not bent during measurement.

Alternative Measurement Postures (If no table is available)

• When no table is available: Sit on a chair, gently place your left arm against your chest, ensuring the cuff is at the same height as your heart. Lightly support your left arm with your right hand during measurement.
• When measuring while lying down: Lie on your back and use a towel or similar item to ensure the cuff is at the same height as your heart.

Note: Measured values may vary slightly depending on the measurement posture.
