Many organizations, including the American Heart Association (AHA), recommend patients diagnosed with hypertension to measure their blood pressure at home. Self-monitoring can help ensure that your medications are working and alert you or your doctor about potential health issues.

Blood pressure devices are widely available and they do not need a prescription. Thus, there is no reason why you should not buy one, especially if you have hypertension. In this article, we are going to discuss some of the important information you need to know about home BP monitors.

Types and Parts of Blood Pressure Monitor for Home Use

There are manual and automatic blood pressure devices but the most recommended ones are electronic or automatic devices.

Blood pressure devices usually have the following basic parts:

#1 Gauge for Readouts

There are BP devices that can take more than one reading as well as report average measurements.

#2 Inflatable Cuff

This component’s inner layer squeezes your arm and is filled with air while it’s outer layer is equipped with a fastener that holds the cuff in place. 

Device Accuracy

Make sure that the BP device is validated before buying it. Its readings should be repeatable and accurate. Your doctor can help you confirm if the device is validated. Also, check your device’s accuracy with your doctor once a year. Your doctor can compare his/her measurements using the office BP monitor with those of yours.

Things to Consider When Buying a BP Monitor

Consider the following features when buying a home-use blood pressure monitor:

#1 Cost

The price of blood pressure monitors vary. Do your research before buying a BP monitor. You are lucky If your health insurance provider covers BP monitor costs.

#2 Display

You should clearly see and easily read your measurement on the device’s display.

#3 Cuff Size

It is important that you get a BP monitor that properly fits in your arm. Poorly fitting cuffs will result in inaccurate measurements. You can ask your nurse or doctor what cuff size is right for you.

Tips to Get Accurate Readings at Home

Below are some tips to ensure that you get reliable blood pressure readings:

#1 Check the Accuracy of Your Device First

Before you use a BP monitor that you just bought, you can ask your doctor to check its accuracy. We also recommend measuring your blood pressure with your doctor watching you. This makes sure that you are using the device properly. 

#2 Take Your Measurement Twice Daily

Take the first measurement in the morning before you eat or take any medication and the other one at night. Take 2 to 3 readings for each measurement cycle to ensure that you get accurate results. However, each reading should have at least a 1-minute to 3-minute interval. If you are using a blood pressure monitor that does not automatically log your blood pressure measurements, better create a record book for your readings.

#3 Place the Device’s Cuff on Your Skin

Do not place the BP monitor’s cuff over clothing. This can result in inaccurate measurements. 

#4 Position Your Arm Properly

When taking blood pressure measurements, make sure that you use one arm for all measurements. Your arm should be resting. Raise it to the same level as your heart. You can use a chair arm, desk, or table. To elevate your arm high enough, place a cushion or pillow under your arm.

#5 Calm Yourself Before & During the Measurement

Before taking your blood pressure levels, rest for around 5 minutes. Make yourself comfortable. Lean back on a chair and your ankles and legs should be uncrossed. Clear your mind and do not think of stressful things. Also, do not talk while having your measurement. 

#6 Avoid Alcohol, Tobacco, & Food Before Taking Your Measurement

Avoid the ones mentioned above 30 minutes prior to taking your blood pressure measurement. You should also empty your bladder first because your reading might increase slightly when your bladder is full.
