4.2 Cuff Selection and Placement

The monitor comes with two cuffs to fit a wide range of arm sizes:

• Medium/Large Cuff: Suitable for arm circumferences of 9"-17" (22-42cm).
• Extra Large Cuff: Suitable for arm circumferences of 13"-21" (32-52cm).

To select the correct cuff, measure your upper arm circumference at the midpoint between your elbow and shoulder. Choose the cuff that best fits this measurement.

Figure 4.2: Importance of correct cuff size for accurate readings.

Cuff Placement:

1. Ensure the cuff's air tube is securely plugged into the monitor's port.
2. Wrap the cuff around your bare upper arm, approximately 2-3 cm (1 inch) above the elbow joint.
3. The air tube should run down the center of your arm, aligned with your brachial artery.
4. The cuff should be snug but not too tight; you should be able to insert two fingers between the cuff and your arm.

5. Operating Instructions

5.1 Before Measurement

For accurate readings, follow these guidelines:

• Rest for at least 5 minutes before taking a measurement.
• Avoid smoking, consuming caffeine, or exercising for at least 30 minutes prior.
• Sit in a comfortable position with your back supported and feet flat on the floor. Do not cross your legs.
• Place your arm on a table so the cuff is at heart level.

5.2 Taking a Measurement

1. Press the START/STOP button. The cuff will automatically inflate and then slowly deflate.
2. Remain still and silent during the measurement.
3. Once the measurement is complete (approximately 30 seconds), your systolic pressure (SYS), diastolic pressure (DIA), and pulse rate (PUL) will be displayed on the large 5-inch backlit LED screen.

6. Understanding Your Readings

Your blood pressure reading consists of two numbers:

• Systolic Pressure (SYS): The top number, which indicates the pressure in your arteries when your heart beats.
• Diastolic Pressure (DIA): The bottom number, which indicates the pressure in your arteries between beats.
• Pulse Rate (PUL): Your heart rate, measured in beats per minute.

The monitor also features a WHO Hypertension Classification Bar on the screen, which visually indicates your blood pressure category based on World Health Organization guidelines (Green: Normal, Yellow: Elevated, Orange: High Blood Pressure Stage 1, Red: High Blood Pressure Stage 2).
