When the reading is 120 mmHg or a little below while a person is sitting quietly at rest, the systolic blood pressure is considered normal.

What Is Diastolic Blood Pressure

The heart rests between beats so it can refill with blood. Doctors call this pause between beats “diastole.” Your diastolic blood pressure is the measurement during this pause before the next heartbeat.

A normal diastolic blood pressure during quiet rest is 80 mmHg or a little below. If you have high blood pressure, the diastolic number is often higher even during quiet rest.

Low diastolic pressure may be seen with dehydration or with severe bleeding. It also may happen if the arteries relax and widen.

Cardiology : What Does Blood Pressure Really Mean

We have all had our blood pressure taken at a regular doctor visit however most of us dont truly understand why those numbers are so important. Having high blood pressure is a big health concern, but what does it all really mean?

What is blood pressure?

In the most basic terms, when your heart beats, it pumps blood throughout your body, supplying it with the oxygen and energy it needs. As your blood moves, it pushes against the sides of your blood vessels. The strength of this pushing is what is known as blood pressure.

When you have your blood pressure reading it consists of two numbers, presented as one number over the other, like a fraction. The first or top number is your systolic blood pressure. This is the amount of pressure in your arteries during the contraction of your heart muscle. The second or bottom number is your diastolic blood pressure. This is the lowest level your blood pressure reaches as your heart relaxes between beats. The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure. For example, the pulse pressure reading for a person whose blood pressure is 120/80, would be 40. Along with blood pressure, pulse pressure can also provide insight into your heart health. In some cases a low pulse pressure may indicate poor heart function, while a higher pulse pressure may reflect leaky heart valves, often as a result of age-related losses in aortic elasticity.

Checking Blood Pressure At Home

High Blood Pressure: How to Understand the Numbers

Keeping track of blood pressure at home is important for many people, especially if you have high blood pressure. This helps you and your doctor find out if your treatment is working.

Your doctor may also suggest that you check your pressure at home if they think you may have “white coat hypertension.” It’s a real condition. The stress of being in a doctor’s office raises your blood pressure, but when you’re home, it’s normal.

Ask your doctor to recommend an easy-to-use home blood pressure monitor. Make sure the cuff fits properly. If your arm is too big for the cuff, the reading may be higher than your blood pressure really is. Ask your doctor for a larger cuff or make sure you buy a home monitor with a cuff that fits you.

You also can use a wrist blood pressure monitor, but they often aren’t as accurate. Follow the directions that come with the device to make sure you are using it correctly.

No matter which type of blood pressure monitor you have, it’s a good idea to take it to your doctor’s office. You can compare its reading to the numbers your doctor gets. Avoid caffeine, cigarettes, and exercise for at least 30 minutes before the test.

When you take your blood pressure at home, sit up straight in a chair and put both feet on the floor. Ask your doctor or nurse to show you the right way to position your arm so you get accurate readings.

Your Blood Pressure Numbers And What They Mean

Your blood pressure is recorded as two numbers:

  • Systolic blood pressure indicates how much pressure your blood is exerting against your artery walls when the heart beats.
  • Diastolic blood pressure indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats.

Blood Pressure Readings Explained

What do the numbers mean?

Everyone would like to have healthy blood pressure. But what exactly does that mean?

When your doctor takes your blood pressure, its expressed as a measurement with two numbers, with one number on top and one on the bottom , like a fraction. For example, 120/80 mm Hg.

The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle. This is called systolic pressure.

The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure.

Both numbers are important in determining the state of your heart health.

Numbers greater than the ideal range indicate that your heart is working too hard to pump blood to the rest of your body.

Understanding Blood Pressure Readings

  • Understanding Blood Pressure Readings

Do you suffer from high blood pressure? It might be surprising, but high blood pressure or hypertension is actually one of the most commonly diagnosed health conditions for Americans. In fact, it is reported that 68 million Americans are currently living with high blood pressure.

Of equal concern is that, within this population, it is estimated that nearly 20% have yet to be diagnosed and are not aware of the potential problem. Undiagnosed cases of high blood pressure are a real concern as damage caused by high blood pressure takes place slowly over time.

Left untreated, high blood pressure can lead to things like heart attack, stroke, heart failure, kidney disease, vision loss and a host of other problems. In this article, we will unpack blood pressure and explain how to interpret readings you may get from a blood pressure monitor. Knowing if you have high blood pressure is extremely important. Taking accurate blood pressure readings and correctly understanding the results of those tests are crucial.

Even if your doctor takes your blood pressure in the clinic, monitoring your blood pressure at home can be useful whether or not you have hypertension.

  • It can tell you if your blood pressure is changing over time, which is important because your risk for hypertension increases as you age.

  • It can come in handy while youre exercising, and tell you if youre exercising at a healthy and safe intensity level.

  • If your doctor suspects that you have hypertension, it can give them a better sense of what your blood pressure is like on a normal basis.

  • If you have hypertension, it can help your doctor see if your treatment plan is working. Current guidelines recommend that patients with hypertension aim for a blood pressure lower than 130/80 mmHg, with the help of lifestyle changes and medications.

  • If you take blood pressure medications, it can be especially helpful if you experience symptoms like headaches or dizziness. Low blood pressure readings during those times can alert your doctor to adjust the dose of your medication or give you a different drug to try. No matter what, do not change how youre taking your medications without talking to your doctor. Call your doctor immediately if you find that your blood pressure is too high or too low, or if you experience symptoms like headaches, dizziness, or fainting.

How To Understand Blood Pressure Readings

Understanding the numbers

You might have heard that the normal blood pressure reading should be around 180/20 mm Hg. So, what exactly does this mean? Well, these two numbers signify systolic and diastolic blood pressure. Systolic blood pressure refers to the pressure applied by the blood vessels on the constricted arteries every time your heartbeats. The normal level for this is around 120 or below. Diastolic blood pressure is the pressure applied on the arteries when the heart rests between two beats. At this point in time, the heart is filled with blood and receives oxygen. The normal level for this has to be below 80. Both of these parameters are useful, as they indicate how healthy your heart is at the moment.

Striving for a normal reading

Red flags

If your systolic blood pressure is between 120 to 129 and your diastolic blood pressure is slightly above 80, then you have slipped into the risky zone. It is not medically considered as high blood pressure, but it is a warning signal for you to inculcate healthier habits and take better care of your heart. If you want to cut down your chances of heart attacks or strokes at this stage, then watching your weight and eating healthy food should definitely become your new mantra.

How Blood Pressure Is Tested

A device called a sphygmomanometer will be used to measure your blood pressure.

This usually consists of a stethoscope, arm cuff, pump and dial, although automatic devices that use sensors and have a digital display are also commonly used nowadays.

It’s best to sit down with your back supported and legs uncrossed for the test. You’ll usually need to roll up your sleeves or remove any long-sleeved clothing, so the cuff can be placed around your upper arm. Try to relax and avoid talking while the test is carried out.

During the test:

  • you hold out one of your arms so it’s at the same level as your heart, and the cuff is placed around it your arm should be supported in this position, such as with a cushion or arm of a chair
  • the cuff is pumped up to restrict the blood flow in your arm this squeezing may feel a bit uncomfortable, but only lasts a few seconds
  • the pressure in the cuff is slowly released while a stethoscope is used to listen to your pulse
  • the pressure in the cuff is recorded at 2 points as the blood flow starts to return to your arm these measurements are used to give your blood pressure reading

You can usually find out your result straight away, either from the healthcare professional carrying out the test or on the digital display.
