Monitoring Your Blood Pressure at Home: A Step-by-Step Guide

Understanding your blood pressure readings is a crucial part of managing hypertension (also commonly known as high blood pressure). The regular monitoring of your blood pressure at home can provide your healthcare provider with a wealth of information about your heart health and can help guide treatment decisions.

Here's a step-by-step guide on how to do it:

Step 1: Purchase a Home Blood Pressure Monitor

Choosing the right home blood pressure monitor is the first step towards effective home monitoring of your blood pressure. Here are a few helpful pointers to help you make the right choice:

• Type of Monitor: Blood pressure monitors come in different types, but for home use, an automatic, cuff-style, bicep (upper arm) monitor is often recommended. These monitors are generally considered more accurate than wrist or finger monitors.

• Validation: Look for a monitor that has been validated, meaning its accuracy has been tested and confirmed by a third party. You can check for validation from organizations such as the British Hypertension Society or the American National Standards Institute.

• Cuff Size: The cuff size is crucial for accurate readings. Most monitors come with a medium-sized cuff. However, if your upper arm is larger or smaller than average, you may need a different-sized cuff. The cuff should wrap smoothly around your upper arm with enough space to slide two fingertips under the cuff.

• Ease of Use: The monitor should be easy to use, with clear instructions and a display that's easy to read. Some monitors offer features like a digital display or spoken instructions which can be helpful for those with vision problems.

• Storage and Connectivity: Some monitors can store readings for later review or download data to a computer or mobile app. This can be useful for tracking your readings over time or for sharing information with your healthcare provider. If you plan to use a mobile health app like Jonda, consider a monitor that can connect to the app.

• Cost and Insurance: The cost of home blood pressure monitors can vary. Check if your insurance covers the cost of a home monitor. If not, consider it a worthwhile investment in your health.

Step 2: Prepare for the Reading

Proper preparation before taking your blood pressure reading is crucial for obtaining accurate results. Here are a few things worth noting to ensure you're well-prepared:

• Avoid Certain Activities: Certain activities can temporarily raise your blood pressure. These include smoking, consuming caffeinated beverages, and engaging in physical exercise. To ensure an accurate reading, avoid these activities for at least 30 minutes before taking your blood pressure.

• Empty Your Bladder: A full bladder can also affect blood pressure readings. Make sure to use the restroom before you take your measurements.

• Rest: It's important to be relaxed when taking your blood pressure. Sit quietly for at least 5 minutes before taking the measurement. This rest period allows your circulatory system to return to its baseline state, ready for an accurate reading.

• Position Your Body Correctly: Sit in a comfortable chair with your feet flat on the floor. Don't cross your legs or ankles, as this can affect the reading. Rest your arm on a flat surface such as a table, with your upper arm at heart level.

• Stay Silent: Talking can elevate your blood pressure, so remain silent during the measurement.

Step 3: Position Your Arm and Cuff Correctly

The correct positioning of your arm and the cuff is crucial for an accurate blood pressure reading. Here's how to do it:

• Arm Position: Rest your arm on a flat surface such as a table or desk, ensuring that your upper arm is at the same level as your heart. This is important because the height of your arm can affect the reading. If your arm is below heart level, your reading may be falsely high; if it's above, the reading may be falsely low.

• Cuff Placement: The cuff should be placed on your bare upper arm, not over clothing. Position the cuff so that the bottom edge is about 1 inch above the crease of your elbow. The tubing should run down the centre of your arm in line with your middle finger. The cuff should be snug but not too tight – you should be able to fit 2 fingers under the cuff.

Step 4: Take Your Reading

Here's a detailed process on how to take your blood pressure reading:

• Follow the Monitor Instructions: Each blood pressure monitor may have slightly different instructions, so it's important to read the manual that came with your device. Some devices inflate the cuff automatically while others require manual inflation.

• Start the Measurement: Once your arm and the cuff are properly positioned as outlined in Step 3, you can start the measurement. For automatic devices, simply press the start button. For manual devices, you'll need to inflate the cuff by squeezing a rubber bulb until the gauge reads about 30 points above your expected systolic pressure.

• Wait for the Reading: Stay still and quiet while the monitor takes the reading. Moving or talking can affect the accuracy of the result. The cuff will slowly deflate, and the monitor will display your blood pressure reading.

• Take Multiple Readings: It's recommended to take at least two readings, one minute apart, in the morning before eating or taking medications, and in the evening before dinner. This provides a more comprehensive picture of your blood pressure behaviour throughout the day.

Step 5: Record Your Readings

Keeping a consistent log of your blood pressure readings is crucial for tracking your progress and helping your healthcare provider make or adjust your treatment plan. Here's how to do it effectively:

• Log Each Reading: After each reading, write down your systolic and diastolic numbers, the date, and the time of day. A good way to keep track of this over time is by entering your blood pressure readings into the Jonda app. This will help you to visualize your blood pressure readings over time.

• Share Your Log: Regularly share your blood pressure log with your healthcare provider, especially if you notice any significant changes. You can easily do this on Jonda the app. Sharing such information can help your healthcare provider assess the effectiveness of your treatment plan and make necessary adjustments.

Step 6: Interpret Your Readings

Interpreting your blood pressure readings is crucial for understanding your cardiovascular health and assessing your hypertension. Here's how to interpret your readings:

• Normal Blood Pressure: A normal blood pressure reading is typically below 120/80 mm Hg. If your readings consistently fall within this range, it indicates that your blood pressure is within a healthy level.

• Elevated Blood Pressure: If your systolic reading ranges from 120 to 129 mm Hg and your diastolic reading remains below 80 mm Hg, you may have elevated blood pressure. This indicates a higher risk of developing hypertension, and lifestyle modifications may be recommended to prevent further increases.

• Stage 1 Hypertension: If your systolic reading falls between 130 and 139 mm Hg or your diastolic reading ranges from 80 to 89 mm Hg, it indicates stage 1 hypertension. At this stage, your healthcare provider may recommend lifestyle changes, such as dietary modifications, increased physical activity, and stress management techniques.

• Stage 2 Hypertension: If your systolic reading is consistently 140 mm Hg or higher, or your diastolic reading is consistently 90 mm Hg or higher, it indicates stage 2 hypertension. In this stage, medication in addition to lifestyle changes may be necessary to manage your blood pressure effectively and reduce the risk of complications.

By monitoring your blood pressure at home, you can take an active role in safeguarding your health, and work with your doctor to better manage your care that will lead to better outcomes and improve your quality of life.
