Blood pressure is the force of blood pushing against the walls of your arteries. It is measured in millimetres of mercury (mmHg) and expressed as two numbers: systolic and diastolic.

Systolic is the pressure when your heart beats, and diastolic is the pressure when your heart rests between beats.

Normal blood pressure is below 120/80 mmHg.

 High blood pressure, or hypertension, is when your blood pressure is consistently above 140/90 mmHg.

Hypertension can damage your heart, blood vessels, kidneys, and other organs. It can also increase your risk of stroke, heart attack, heart failure, kidney failure, and vision loss.

Low blood pressure, or hypotension, is when your blood pressure is consistently below 90/60 mmHg. Hypotension can cause dizziness, fainting, nausea, fatigue, and blurred vision.

It can also indicate an underlying condition, such as dehydration, blood loss, infection, or heart problems.

Monitoring your blood pressure at home can help you keep track of your health and detect any changes that may require medical attention.

It can also help you manage your blood pressure with lifestyle changes and medication, if prescribed by your doctor.

In this article, we will guide you through the steps of blood pressure monitoring at home, and provide you with some tips and best practices to ensure accurate and reliable results.

What You Need to Monitor Your Blood Pressure at Home

To monitor your blood pressure at home, you will need a blood pressure monitor, also known as a sphygmomanometer.

There are different types of blood pressure monitors, but the most common and easy to use are the digital ones.

A digital blood pressure monitor consists of a cuff that wraps around your upper arm, and a device that displays your blood pressure readings. Some models also have a memory function that stores your previous readings, and a Bluetooth function that connects to your smartphone or computer.

You can buy a blood pressure monitor from a pharmacy, a medical supply store, or online. Make sure to choose a monitor that has been validated by a reputable organization, such as the American Heart Association (AHA), the British Hypertension Society (BHS), or the European Society of Hypertension (ESH).

You can check their websites for a list of validated monitors.

You should also choose a monitor that fits your arm size. The cuff should be snug but not too tight, and cover about 80% of your upper arm. If the cuff is too small or too large, it can affect the accuracy of your readings.

You can measure your arm circumference and compare it to the cuff size chart provided by the manufacturer.

How to Monitor Your Blood Pressure at Home

To monitor your blood pressure at home, follow these steps:

Step 1. Prepare yourself.

Avoid smoking, drinking caffeine or alcohol, eating, exercising, or taking medication that can affect your blood pressure for at least 30 minutes before measuring.

Sit quietly and relax for at least 5 minutes before measuring. Use the bathroom if needed, as a full bladder can raise your blood pressure.

Step 2. Choose a comfortable and quiet place.

Sit in a chair with a back support and a flat surface, such as a table, in front of you. Place your feet flat on the floor and your legs uncrossed.

Rest your arm on the table, with your palm facing up and your elbow slightly bent. Make sure your arm is at the same level as your heart.

3. Wrap the cuff around your arm.

Place the cuff about 2 cm above your elbow, with the tube running down the centre of your inner arm. Make sure the cuff is not too loose or too tight.

You should be able to fit one finger between the cuff and your arm.

4. Turn on the monitor and press the start button.

The cuff will inflate and deflate automatically. Do not move, talk, or touch the monitor while it is measuring. Wait until the monitor displays your blood pressure readings.

Note down the systolic and diastolic numbers, and the date and time of the measurement.

Some monitors also display your pulse rate, which is the number of times your heart beats per minute.

5. Repeat the measurement.

Wait for at least one minute before taking another reading. You can take up to three readings and calculate the average.

If the readings vary by more than 5 mmHg, take more readings until they are consistent.

6. Record and share your results.

Keep a log of your blood pressure readings, either on paper, on your monitor’s memory, or on an app.

You can also share your results with your doctor, nurse, or pharmacist, who can help you interpret them and adjust your treatment plan if needed.

Tips and Best Practices for Blood Pressure Monitoring at Home

To ensure accurate and reliable blood pressure monitoring at home, follow these tips and best practices:

Use the same arm and monitor every time.

This will help you compare your readings over time and detect any changes. If you have to use a different arm or monitor, note it down in your log.

Measure your blood pressure at the same time every day.

This will help you avoid the effects of daily fluctuations and external factors. The best time to measure your blood pressure is in the morning, before breakfast and medication, and in the evening, before dinner and medication.

Measure your blood pressure regularly.

This will help you track your progress and see the effects of your lifestyle changes and medication. The frequency of your measurements depends on your condition and your doctor’s advice.

Generally, you should measure your blood pressure at least once a week, or more often if your blood pressure is high or unstable.

Check your monitor’s accuracy and battery.

This will help you avoid errors and malfunctions. You should check your monitor’s accuracy at least once a year, by comparing it to a manual blood pressure monitor used by a health professional. You should also check your monitor’s battery regularly, and replace it when it is low.

Do not rely solely on your monitor.

This will help you avoid complacency and false reassurance. You should also pay attention to your symptoms, such as headaches, chest pain, shortness of breath, or blurred vision, and seek medical help if they worsen or persist.

You should also follow your doctor’s advice on lifestyle changes and medication, and attend your regular check-ups and tests.
