1. Introduction
1.1. Your automatic blood pressure monitor
Thank you for purchasing a fully automatic blood pressure monitor. Your monitor is
designed to provide fast and reliable digital readings of your pulse, and systolic /
diastolic blood pressure using the oscillometric method on your upper arm. It offers
clinically proven accuracy and has been designed to be user friendly.
Before using your blood pressure monitor, please read this instruction manual
carefully to ensure correct use. If you have additional questions regarding blood
pressure measurements please contact your doctor.
1.2. ™ Measurement System
™, our most advanced system to date, combines clinical accuracy and
premium features including:
• A quieter, more comfortable measurement experience that reduces the amount of
time your arm is under pressure. Less pressure = more comfort!
• An ergonomic cuff design that is easier to use and fits a wider range of arm sizes
(for arms 8.7”-16.5”).
2. How is blood pressure measured?
2.1. What is blood pressure, and why does it fluctuate?
Your level of blood pressure is determined in the circulatory center of the brain and
adjusts to a variety of situations through feedback from the nervous system. To
adjust blood pressure, the strength and frequency of the heart (pulse), as well as the
width of circulatory blood vessels is altered. Blood vessel width is affected by fine
muscles in the blood vessel walls.
Your level of arterial blood pressure changes periodically during heart activity. During
the "blood ejection" (Systole), the value is highest (systolic blood pressure value). At
the end of the heart’s "rest period" (Diastole), pressure is lowest (diastolic blood
pressure value).
Blood pressure values must lie within certain normal ranges in order to prevent
particular diseases.
