Every year, millions of people around the globe are affected by hypertension or high blood pressure. With a reputation of being a silent killer, high blood pressure triggers more strokes and heart attacks than any other disease.
The treatment of hypertension involves regular monitoring of your blood pressure. And, a home blood pressure monitor is an easy and convenient way by which you can avoid regular visits to the doctor to have your blood pressure checked and helps to keep track of your readings right at home.
Many times, for people suffering from hypertension, checking their blood pressure once in a while at the doctor’s clinic may not be sufficient and they may have to do it more often. In such cases, it is a sensible decision to invest in an inexpensive and simple blood pressure monitor. This is especially useful if you have started some new treatment for blood pressure control.
And, the best part is that you don’t require a doctor’s prescription to buy a blood pressure monitor for your home. However, before investing in one, you should be aware of the various kinds of blood pressure monitors available, their features, etc.

What Is Blood Pressure?
High blood pressure is a condition that affects hundreds of people around every day. The human body requires oxygen and energy to function and this is provided when the heart beats and pumps the blood to the various parts of the body.
When the blood moves throughout the body, it exerts pressure on the sides of the blood vessels. This force exerted by the blood on the blood vessels and the measurement of the force used by the heart to pump out blood is known as blood pressure.
If the pressure of the blood is very high, it exerts a lot of strain on the arteries and on the heart, which may lead to heart attack and stroke.
How Is Blood Pressure Measured?
Blood pressure is usually measured in mmHg or millimeters of mercury. When you take a blood pressure reading, it usually comprises 2 levels and shows as one reading on top of the other.
Systolic Blood Pressure
The reading on the top is known as the systolic blood pressure, which essentially is the highest level of the blood pressure when the heart beats or the pressure when the heart pumps the blood out.
Diastolic Blood Pressure
The number at the bottom is the diastolic blood pressure, which is the lowest level reached by the blood pressure when the heart relaxes in between the beats.
Generally, blood pressure readings are:
How Does Blood Pressure Affect Your Health?
High Blood Pressure
High blood pressure is associated with unhealthy habits such as being overweight, drinking a lot of alcohol, smoking and not having sufficient exercise. High blood pressure puts excess strain on your heart and the blood vessels, which can cause them to get damaged and become weak over time.
The condition of high blood pressure must be controlled or this can increase your risk of developing several serious health problems that can affect the various parts of the body such as:
And, if you suffer from other health problems such as high cholesterol and diabetes, your risk of health problems become greater.
Low Blood Pressure
On the other hand, the condition of low blood pressure is not very common and can be caused due to conditions such as dehydration or heart failure, or it can be a side effect of some medicines.
What Is A Blood Pressure Monitor?
The device that is used to measure blood pressure is known as a blood pressure monitor or a sphygmomanometer, blood pressure meter or a blood pressure gauge. Typically, a blood pressure monitor comprises an inflatable cuff that collapses and releases the artery in a controlled way and an aneroid gauge or a mercury manometer measures the pressure.
The monitor also has a means by which it is inflated manually by means of a valve and bulb or a pump that is electrically operated.
The blood pressure monitor is used along with some method that helps to determine the pressure at which the blood flow begins and the pressure at which the blood flow is unconstrained. Usually, manual sphygmomanometers are used along with a stethoscope.
Different Types Of Blood Pressure Monitors And How They Work
The auscultatory method is a manual method by which blood pressure is measured. This is also known as the Riva Rocci Korotkoff method and is the gold standard in blood pressure measurement, where the trained medical practitioner makes use of the sphygmomanometer and by making use of a stethoscope, listens to the Korotkoff sounds in the brachial artery.
In the case of digital blood pressure monitors, they make use of electronic calculations and oscillometric measurements instead of auscultation. They either use manual or automatic methods of inflation, both are electronic, they can be used in environments that are noisy and can be operated without any training.
The systolic and diastolic pressures are measured by making use of oscillometric detection.
The measurement of blood pressure by using digital oscillometric monitors may not be as accurate as manual meters and they may not be recommended for use for patients suffering from conditions such as arrhythmia, arteriosclerosis, preeclampsia, etc., as the calculations may not be accurate and for such conditions, it may be better to use an analog sphygmomanometer.
The oscillometric method of measuring blood pressure may produce different readings compared to when determined using the method of auscultation and they vary due to various factors such as heart rate, arterial stiffness and pulse pressure.
How Did Blood Pressure Monitors Improve Over The Years?
Over the years, there have been several advancements in the blood pressure monitor technology and today you have options such as:
App-Based Blood Pressure Monitors
Some models of blood pressure monitors can connect to your smart device wirelessly and enables you to store your data and track it electronically.
These app-based blood pressure monitors offer better data logging functions when compared to the traditional standalone monitors.
They offer features such as data manipulation and ability to produce graphs, longer storage of history and the ability to connect with other health apps for more complete monitoring of your overall health.
Usually, app-based monitors do not have their own display and you need to use your phone before taking a blood pressure measurement.
You need to pair your smartphone with your blood pressure monitor, which may make the process a bit complex, especially if you are not very comfortable using technology.
Some of the models of blood pressure monitors collect the readings of the user and store them; some models can do it for as many as 6 people.
The reading storage function is especially beneficial if you have more than one person suffering from high blood pressure in your home or you want to buy a single monitor with advanced features rather than having multiple monitors.
There are blood pressure monitors which can store up to 60 readings.
Some monitors allow you to download your readings onto your computer or laptop and some even come with storage devices like memory sticks that enable you to store all your readings.
This could be particularly useful if you want to share your blood pressure readings with your doctor.
How To Measure Your Blood Pressure?
Blood pressure can be measured by following the steps below:
Some tips to follow when taking blood pressure readings:
Upper Arm Cuff Vvs Wrist Blood Pressure Monitors
Upper Arm Cuff Blood Pressure Monitors
These are the more commonly used blood pressure monitoring devices. These blood pressure monitors are usually used by doctors or healthcare professionals to take the blood pressure. Upper arm cuff monitors are usually very accurate.
They are easy to keep at the level of the heart in order to get accurate readings. Upper arm blood pressure monitors usually have larger displays that are easier to read.
However, they are quite uncomfortable and bulky when compared to other devices to monitor blood pressure. The cuff of these monitors is difficult to put on, especially if you’re doing it with one hand.
Wrist Blood Pressure Monitors
These models are gradually becoming popular and resemble large wrist watches. These blood pressure monitor models are comparatively smaller and unnoticeable when compared to upper arm cuff blood pressure monitors. Wrist blood pressure monitors are easier to put on, but to get an accurate reading, it may be difficult to keep them at the necessary height.
Wrist blood pressure monitors are much smaller in size and so if you’re traveling they are very easy to pack and carry along. Although they are very convenient to use and the technology is also improving, wrist blood pressure monitors are still not as accurate as upper arm cuff blood pressure monitors.
Why Different Measuring Spots Can Produce Very Different Results
As we grow older, the blood vessels may harden because of arteriosclerosis or may become narrow because of calcification. This especially affects the arteries located in the wrist, as they are located farther away from the heart.
This makes the accurate measurement of blood pressure more difficult. This is the reason why older people and people who smoke must take their blood pressure readings on the upper arm. People with diabetes may have porous or calcified arteries, which makes them unsuitable for wrist blood pressure monitors.
Usually, the readings taken on the upper arm is different compared to the measurements taken on the wrist. If you are using a wrist blood pressure monitor, then your wrist must be positioned at the level of your heart.
If the wrist is placed flat on the table if you are sitting, then the blood pressure will be elevated by around 7-8 mmHg as there is a difference in the level of the heart and the wrist, i.e. 1.5 cm = 1 mmHg.
You will also get incorrect readings if you measure the blood pressure at the wrist in the case you have any changes in the arteries in your wrist due to old age or if you suffer from cardiac arrhythmia. Wrist blood pressure monitors also may produce wrong readings for older people.
However, the arteries in the upper arm are not so sensitive to such things and so it is recommended that you take blood pressure readings on the upper arm.

How To Get The Most Accurate Blood Pressure Measurement
When you are measuring your blood pressure, you need to follow the correct technique, as if you do it wrong, you can get a reading that is either too high or very low. Before you begin taking readings with your blood pressure monitor at home, check your machine against the machine at your doctor’s clinic.
Next, ensure that the size of the cuff is correct and that the inflatable portion covers at least 80 percent of the upper arm.
Measure your blood pressure early in the morning before taking your medication for blood pressure and then check again in the evening. You should follow this routine when you first begin taking blood pressure readings at home.
Later, you can follow the routine as recommended by your medical practitioner or check your blood pressure once or twice in a month.
Tips to get accurate blood pressure readings:
How Often Should I Get My Blood Pressure Monitor Calibrated?
Since the blood pressure monitor is automatic, to ensure that it gives accurate readings, the device must be calibrated once in 2 years. In order to re-calibrate your home blood pressure monitor, you will have to send it to the manufacturer, who may charge you a re-calibration fee.
