Preparation for Measurement
For accurate readings, follow these preparation steps:
- Sit comfortably with your back straight and supported.
- Keep your feet flat on the floor.
- Rest your arm on a flat surface so the cuff will be at heart level.
- Ensure you have not exercised, eaten, consumed alcohol, smoked, or bathed within 30 minutes prior to measurement.
Applying the Cuff
- Insert the balloon tube of the cuff into the designated port on the monitor.
- Place the cuff on your upper arm, ensuring the bottom edge of the cuff is 2-3 cm (0.8-1.2 inches) above your elbow.
- The air tube should run down the center of your arm.
- Wrap the cuff snugly around your arm. Ensure there is enough looseness to allow a two-finger gap between the cuff and your arm.
- Confirm the cuff is at heart level.
Taking a Measurement
- After properly applying the cuff and preparing for measurement, press the START/STOP button.
- The cuff will automatically inflate, and the measurement will begin.
- Remain still and silent during the measurement.
- Once the measurement is complete, the systolic, diastolic, and pulse rate readings will be displayed on the screen.
Understanding Your Results
The monitor includes a blood pressure level indicator to help you interpret your readings. The color bands on the display provide a general reference:
- Green: Normal blood pressure (SYS: 90-139 mmHg or DIA: 60-89 mmHg)
- Yellow: Elevated blood pressure (SYS: 140-159 mmHg or DIA: 90-99 mmHg)
- Red: High blood pressure (SYS ≥ 160 mmHg or DIA ≥ 100 mmHg)
Note: These color bands are for reference only and are not intended for diagnostic purposes. Always consult a healthcare professional for diagnosis and treatment.
