OSTAR Heart spectrum blood pressure measurement

  • Make the daily measurement at the same time or at the time recommended by your doctor

  • Relax and rest about 5 minutes before taking a measurement

  • After eating, smoking, or exercising wait about 30 minutes before taking a measurement

  • After making a measurement wait about 5 to 10 minutes before taking another measurement

Step 1

Turn on the OSTRA heart spectrum blood pressure monitor by pressing the green "ON/OFF" button.

Step 2

Wear the measuring cuff around the left/right upper arm and comfortably tighten it around 2 cm above the elbow joint. Make sure that the cuff can be turned slightly around the arm.

Step 3

Make sure the cuff is located at the same level of height of the heart. Straight the arm and adjust the cuff to keep the tube parallel to the midline of the arm and straighten to the middle finger.

Step 4

Sit comfortably on a chair, preferably with back support, and relax.

Step 5

Press on the orange button "START" to start the measuring.

In case of emergency

If you feel uncomfortable or have problems while the OSTAR HK-809 heart spectrum blood pressure monitor inflates the cuff or performs the measurement, you can press the green button "ON/OFF" on the right side of the OSTAR HK-809 heart spectrum monitor to interrupt the measurement. As soon as the "ON/OFF" button is pressed, the OSTAR HK-809 heart spectrum blood pressure monitor deflates the cuff immediately until the cuff is completely deflated.
