Understanding Blood Pressure Readings with Blood Pressure Monitor
What is blood pressure?
Blood pressure refers to the force of the body’s blood pushing against the inner walls of the blood vessels, especially the arteries. Each time the heart contracts, it pumps blood into the arteries. Blood pressure monitor measure your blood pressure.
What is the ideal blood pressure?
The ideal blood pressure should be below 120/80 mmHg and above 90/60 mmHg.
You have high blood pressure if you are above 120/80 mmHG. You have low blood pressure if you have readings below 90/60 mmHg.
Your blood pressure doesn’t stay constant throughout the day. It is lowest when you’re sleeping, and rises when you get up and start moving about. It can also go up when you are excited, nervous or physically active. Systolic pressure refers to the blood pressure in the arteries that results when your heart contracts or beats, pushing blood out. When your heart relaxes between beats, blood pressure in the arteries falls. This is the diastolic pressure.
How to read your blood pressure reading?
Blood pressure is typically recorded as 2 numbers, typically presented as a ratio like this in all blood pressure monitor:
Read as “117 over 76 millimeters of mercury”
OR simply as
117 over 76
The top number (the higher of the two numbers shown) measures the pressure in the arteries when the heart beats (which is when the heart muscle contracts).
The bottom number (the lower of the two numbers) measures the pressure in the arteries between heartbeats (that is when the heart muscle is resting between beats and refilling with blood).
A healthy blood pressure reading should be lower than 120/80 mmHg. Normal blood pressure is less than 120 mmHg systolic and 80 mmHg diastolic (see blood pressure chart), and may vary from 90/60mmHg to 120/80mmHg in a healthy young woman. A blood pressure of 140/90 mmHg or higher indicates high blood pressure.
Blood Pressure Level Categories
Categories For Blood Pressure Levels In Adults (Aged 18 Years And Older)
Blood Pressure Level (mmHg)
80 – 89
|High Blood Pressure|
|Stage 1 Hypertension|
140 – 159
90 – 99
|Stage 2 Hypertension|
|* Isolated Systolic Hypertension|
1. When systolic and diastolic blood pressures fall into different categories, the higher category should be used to classify blood
pressure level.For example, 160/80 mmHg would be stage 2 hypertension (high blood pressure).
2.*Isolated systolic hypertension is graded according to the same level of systolic BP.
Blood Pressure Measuring at Home / Office
Anyone can measure your own blood pressure at home with a digital blood pressure monitor that can be purchased at pharmacies, health care stores etc. Read the instructions carefully. You may wish to calibrate your reading with your family doctor. However that is usually not needed as almost all commercial units comes calibrated.
The proper time to take the measurement is when you are at rest. Please refrain from any physical activities 30 minutes before each measurement. These will help to ensure the accuracy of your reading:
- Sit in a comfortable position
- Place your LEFT arm, raised to the level of your heart, on a table or desk, and sit still (take note that the left arm is preferred as your heart is positioned at the left-centre of your body)
- Wrap the cuff of the blood pressure monitor smoothly and snugly around the upper part of your bare arm
Why is my blood pressure fluctuating? Is my BPM faulty?
Researchers from the “Center for Health Research and Rural Advocacy at Geisinger Health System” in Pennsylvania have found that time of day and time of year can influence blood pressure readings by as much as 40%.
Doctors have also found that blood pressure also fluctuates with physical activity and emotional state, it would be better if you can measure your blood pressure at the same time everyday, under resting conditions and on more than one occasion. This will allow the results be comparable easier.
Do not be alarmed if your blood pressure machines seems erratic.
Firstly, Do make sure you read the instructions thoroughly. If need to, you can refer to some Youtube clips.
Do make sure your blood pressure machine is from a trusted brand. Most of the highly reputed brands of blood pressure machines are established brand names from Japan or Europe. Secondly, ensure that the products you bought is from an Authorised Dealers, beware of fakes. Authorised Dealers means that you can have peace of mind as any errors can be solved by re-calibrating by the brand staff in their customer service offices.

Do note that there are many merchants are parallel importing blood pressure monitors with no government approvals. Hence, they are not responsible for minor defects and quality lapses. Only authorised dealers has warranty coverage and calibration offers to re-calibrate your blood pressure monitors. These are the reason why government regulates the import and sales of blood pressure monitors.
Do take heed and get only from trusted, established blood pressure machines from Authorised dealers in Singapore.
