Research suggests that you may not notice symptoms of high blood pressure at first, but it may still be damaging your heart and blood vessels. Your blood pressure is the force your blood exerts on your blood vessels. Experts say that untreated high blood pressure may lead to serious health problems like heart attack, stroke, or kidney problems.

To monitor your blood pressure, pick up an automatic, cuff-style blood pressure monitor that you can use at home from a pharmacy or medical supply store.

Before checking your blood pressure, you need to prepare yourself for an accurate reading by not eating, drinking, or exercising in the 30 minutes before your test.

During the test, sit still with your back straight, legs uncrossed, and feet flat on the floor.

This can help give you the most accurate readings of your pressure in addition to being more simple to use than aneroid sphygmomanometers, which is the technical name of hand-employed blood pressure monitors.

Choose a monitor that is validated and approved by an international organization such as the Association for the Advancement of Medical Instrumentation, the British Hypertension Society and the International Protocol for the Validation of Automated BP Measuring Devices.

If you have special needs, such as being elderly or pregnant, make sure to choose a monitor specifically suited to your purposes. You can buy blood pressure monitors at many pharmacies and most medical supply stores.

Make sure you can return or exchange if the apparatus doesn't work or malfunctions. Set up to check your blood pressure. There are many factors that can affect your blood pressure reading.Want to keep track of your blood pressure?

Microsoft Excel can help you automatically generate charts from recorded data to determine the state of your health or that of a loved one. The Blood Pressure Tracker Template for Excel provides sections for adding daily blood pressure and heart rate information, which is automatically presented in the form of a blood pressure chart.

This template provides two worksheets, one for adding data and the other for displaying a chart for your data. Once done, your chart will automatically be updated the moment you enter information about the Systolic and Diastolic Blood Pressure and the heart rate.

Having a visual representation at your disposal can make it that much easier for you to determine the closeness of the blood pressure and heart rate to normal levels; to identify any worrying trends in due course of time. It takes me to the same page.

It is initiated by the contraction of the ventricles of the heart. Ventricular contraction ejects blood into the major arteries, resulting in flow from regions of higher pressure to regions of lower pressure, as blood encounters smaller arteries and arterioles, then capillaries, then the venules and veins of the venous system. This section discusses a number of critical variables that contribute to blood flow throughout the body.

It also discusses the factors that impede or slow blood flow, a phenomenon known as resistance. As noted earlier, hydrostatic pressure is the force exerted by a fluid due to gravitational pull, usually against the wall of the container in which it is located. One form of hydrostatic pressure is blood pressure, the force exerted by blood upon the walls of the blood vessels or the chambers of the heart. Blood pressure may be measured in capillaries and veins, as well as the vessels of the pulmonary circulation; however, the term blood pressure without any specific descriptors typically refers to systemic arterial blood pressure—that is, the pressure of blood flowing in the arteries of the systemic circulation.

In clinical practice, this pressure is measured in mm Hg and is usually obtained using the brachial artery of the arm. Arterial blood pressure in the larger vessels consists of several distinct components: systolic and diastolic pressures, pulse pressure, and mean arterial pressure. When systemic arterial blood pressure is measured, it is recorded as a ratio of two numbers e. The systolic pressure is the higher value typically around mm Hg and reflects the arterial pressure resulting from the ejection of blood during ventricular contraction, or systole.

The diastolic pressure is the lower value usually about 80 mm Hg and represents the arterial pressure of blood during ventricular relaxation, or diastole. Figure 1. The graph shows the components of blood pressure throughout the blood vessels, including systolic, diastolic, mean arterial, and pulse pressures.

As shown in Figure 1, the difference between the systolic pressure and the diastolic pressure is the pulse pressure. For example, an individual with a systolic pressure of mm Hg and a diastolic pressure of 80 mm Hg would have a pulse pressure of 40 mmHg. Generally, a pulse pressure should be at least 25 percent of the systolic pressure.

A pulse pressure below this level is described as low or narrow.

This may occur, for example, in patients with a low stroke volume, which may be seen in congestive heart failure, stenosis of the aortic valve, or significant blood loss following trauma. In contrast, a high or wide pulse pressure is common in healthy people following strenuous exercise, when their resting pulse pressure of 30—40 mm Hg may increase temporarily to mm Hg as stroke volume increases.

A persistently high pulse pressure at or above mm Hg may indicate excessive resistance in the arteries and can be caused by a variety of disorders. Chronic high resting pulse pressures can degrade the heart, brain, and kidneys, and warrant medical treatment.

Mean is a statistical concept and is calculated by taking the sum of the values divided by the number of values. Although complicated to measure directly and complicated to calculate, MAP can be approximated by adding the diastolic pressure to one-third of the pulse pressure or systolic pressure minus the diastolic pressure:. Normally, the MAP falls within the range of 70— mm Hg. If the value falls below 60 mm Hg for an extended time, blood pressure will not be high enough to ensure circulation to and through the tissues, which results in ischemia, or insufficient blood flow.

A condition called hypoxia, inadequate oxygenation of tissues, commonly accompanies ischemia. The term hypoxemia refers to low levels of oxygen in systemic arterial blood. Neurons are especially sensitive to hypoxia and may die or be damaged if blood flow and oxygen supplies are not quickly restored. After blood is ejected from the heart, elastic fibers in the arteries help maintain a high-pressure gradient as they expand to accommodate the blood, then recoil.Blood pressure measures the extent of the force of blood on your blood vessel walls as your heart pumps.

Systolic blood pressure is the top number in a reading. It measures the pressure on blood vessels as your heart squeezes blood out to your body. Diastolic blood pressure is the bottom number in a reading.

It measures the pressure on blood vessels in between heart beats, while your heart fills up with blood returning from your body. To manage your blood pressure, you need to know which blood pressure numbers are ideal and which ones are cause for concern. Following are the blood pressure ranges used to diagnose hypotension and hypertension in adults.

In general, hypotension relates more to symptoms and specific situations than to exact numbers. The numbers for hypotension serve as a guide, while the numbers for hypertension are more precise.

When looking at these numbers, notice that only one of them needs to be too high to put you in a hypertensive category. Blood pressure levels are different for children than they are for adults. Blood pressure targets for children are determined by several factors, such as:. There are a few ways to check your blood pressure. For example, your doctor can check your blood pressure in their office. Many pharmacies also offer free blood pressure monitoring stations.

You can also check it at home using home blood pressure monitors. These are available for purchase from pharmacies and medical supply stores. The American Heart Association recommends using an automatic home blood pressure monitor that measures blood pressure on your upper arm. Wrist or finger blood pressure monitors are also available but may not be as accurate. Your reading may indicate a blood pressure problem even if only one number is high. Talk to your doctor about how often you should check your blood pressure at home.

Write the results in a blood pressure journal and share them with your doctor. If you have high blood pressure, your doctor may watch it closely.

Elevated blood pressure is a condition that puts you at risk for hypertension. If you have it, your doctor may suggest lifestyle changes such as eating a heart-healthy diet, cutting back on alcohol, and exercising regularly. These may help bring your blood pressure numbers down.High blood pressure, or hypertension, is a common condition that occurs when your blood pressure—the force of the blood on the walls of your arteries—is often too high.

High blood pressure is a common disease that develops when blood flows through your arteries at higher-than-normal pressures.

How to Read a Blood Pressure Chart to Determine Your Risk of Hypertension

Your blood pressure is made up of two numbers: systolic and diastolic. Systolic pressure is the pressure when the ventricles pump blood out of the heart. Diastolic pressure is the pressure between heartbeats, when the heart is filling with blood.

That is why it is important to have your blood pressure checked regularly. Your doctor will diagnose you with high blood pressure if you have consistently high blood pressure readings. To control or lower high blood pressure, your doctor may recommend that you adopt a heart-healthy lifestyle. This includes choosing heart-healthy foods such as those in the DASH eating plan. You may also need to take medicines. Controlling or lowering blood pressure can help prevent or delay serious health problems such as chronic kidney disease, heart attack, heart failure, stroke, and possibly vascular dementia.

During High Blood Pressure Education Month in May and throughout the year, the NHLBI features research findings that help advance our understanding of high blood pressure, materials to share in person or on social media, and resources for managing your condition.

Find research studies and get resources on high blood pressure. Many factors raise your risk of high blood pressure. Some risk factors, such as unhealthy lifestyle habits, can be changed. Other risk factors, such as age, family history and genetics, race and ethnicity, and sex, cannot be changed. A healthy lifestyle can lower your risk for developing high blood pressure.

Blood pressure tends to increase with age. Our blood vessels naturally thicken and stiffen over time. These changes increase the risk for high blood pressure. However, the risk of high blood pressure is increasing for children and teens, possibly because of rise in the number of children and teens who are living with overweight or obesity. High blood pressure often runs in families. Much of the understanding of the body systems involved in high blood pressure has come from genetic studies.

Many different genes are linked to a small increase in the risk of developing high blood pressure. Research suggests that certain DNA changes as an unborn baby grows in the womb may also lead to high blood pressure later in life.

Some prescription and over-the-counter medicines can make it more difficult for your body to control your blood pressure. Medicines that can raise your blood pressure include antidepressants, decongestants medicines to relieve a stuffy nosehormonal birth control pills, and non-steroidal anti-inflammatory drugs NSAIDs such as aspirin or ibuprofen. Other medical conditions change the way your body controls fluids, sodium, and hormones in your blood.

Other medical causes of high blood pressure include:. High blood pressure is more common in African American and Hispanic adults than in white or Asian adults. Compared with other racial or ethnic groups, African Americans tend to have higher average blood pressure numbers and get high blood pressure earlier in life. Experiencing discrimination has been tied to high blood pressure. In addition, some high blood pressure medicines may not work as well in African Americans.

During pregnancy, African American women are more likely than white women to develop preeclampsia. Preeclampsia is a pregnancy disorder that causes sudden high blood pressure and problems with the kidneys and liver. Men are more likely than women to develop high blood pressure throughout middle age. But in older adults, women are more likely than men to develop high blood pressure.

Women who have high blood pressure during pregnancy are more likely to have high blood pressure later in life. Recent research has shown that factors such as income, your education, where you live, and the type of job you have may contribute to your risk of developing high blood pressure.The vital importance of the heart is obvious.

If one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximatelytimes in one day, more than 39 million times in one year, and nearly 3 billion times during a year lifespan. Each of the major pumping chambers of the heart ejects approximately 70 mL blood per contraction in a resting adult. This would be equal to 5. Over one year, that would equal 10, liters or 2. In order to understand how that happens, it is necessary to understand the anatomy and physiology of the heart.

Physiology of Circulation

The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Within the mediastinum, the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium, or pericardial sac, and sits in its own space called the pericardial cavity.

The dorsal surface of the heart lies near the bodies of the vertebrae, and its anterior surface sits deep to the sternum and costal cartilages.

The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base. The base of the heart is located at the level of the third costal cartilage, as seen in Figure 1. The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages.

Blood Pressure in Arteries, Veins and Capillaries

The right side of the heart is deflected anteriorly, and the left side is deflected posteriorly. It is important to remember the position and orientation of the heart when placing a stethoscope on the chest of a patient and listening for heart sounds, and also when looking at images taken from a midsagittal perspective.

The slight deviation of the apex to the left is reflected in a depression in the medial surface of the inferior lobe of the left lung, called the cardiac notch. Figure 1.

The heart is located within the thoracic cavity, medially between the lungs in the mediastinum. It is about the size of a fist, is broad at the top, and tapers toward the base.

By applying pressure with the flat portion of one hand on the sternum in the area between the lines in the image belowit is possible to manually compress the blood within the heart enough to push some of the blood within it into the pulmonary and systemic circuits.

This is particularly critical for the brain, as irreversible damage and death of neurons occur within minutes of loss of blood flow. If you are unfamiliar with this song, you can likely find a version of it online. At this stage, the emphasis is on performing high-quality chest compressions, rather than providing artificial respiration.

CPR is generally performed until the patient regains spontaneous contraction or is declared dead by an experienced healthcare professional. When performed by untrained or overzealous individuals, CPR can result in broken ribs or a broken sternum, and can inflict additional severe damage on the patient.Measure your blood pressure regularly to help your health care team diagnose any health problems early.

Measuring your blood pressure is the only way to know whether you have high blood pressure. High blood pressure usually has no warning signs or symptoms, and many people do not know they have it. First, a health care professional wraps an inflatable cuff around your arm.

If using a digital or automatic blood pressure cuff, the health care professional will not need to use a stethoscope.

The gauge uses a unit of measurement called millimeters of mercury mmHg to measure the pressure in your blood vessels. Learn more about blood pressure measurements. Talk with your health care team about regularly measuring your blood pressure at home, also called self-measured blood pressure SMBP monitoring.

These blood pressure monitors are easy and safe to use. A health care team member can show you how to use one if you need help. Learn about the proper way to measure your blood pressure and things that can affect your blood pressure reading. Talk with your health care team about how often you should have your blood pressure measured or when to measure it yourself.

People who have high blood pressure may need to measure their blood pressure more often than people who do not have high blood pressure. If you are concerned about your blood pressure numbers, talk to your health care team.

They can help you make a plan to manage high blood pressure. No matter your age, you also can take steps each day to help keep your blood pressure in a healthy range. Use this printable and shareable list of questions to ask your health care team to help you manage your blood pressure.
