How do health care professionals measure my blood pressure?First, a health care professional wraps an inflatable cuff around your arm. The health care professional then inflates the cuff, which gently tightens on your arm. The cuff has a gauge on it that will measure your blood pressure. The health care professional will slowly let air out of the cuff while listening to your pulse with a stethoscope and watching the gauge. This process is quick and painless. 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. If you have high blood pressure, talk to your health care team about steps to take to control your blood pressure to lower your risk for heart disease and stroke.

How can I measure my blood pressure at home?Talk with your health care team about regularly measuring your blood pressure at home, also called self-measured blood pressure (SMBP) monitoring.

A health care team member can show you how to use one if you need help. Evidence shows that people with high blood pressure are more likely to lower their blood pressure if they use SMBP combined with support from their health care team than if they don’t use SMBP.3 Use these additional tips for SMBP:4 How often should I measure my blood pressure?Talk with your health care team about how often you should have your blood pressure measured or when to measure it yourself.

Blood pressure is the amount of force your blood uses to get through your arteries. When your heart pumps, it uses force to push oxygen-rich blood out to your arteries. They bring it to your body’s cells and tissues. If your blood pressure is too high, it can cause health issues. The only way to know your blood pressure is to measure it.
Blood pressure is the measurement of the pressure or force of blood inside your arteries. Each time your heart beats, it pumps blood into arteries that carry blood throughout your body. This happens 60 to 100 times a minute, 24 hours a day. Arteries deliver oxygen and nutrients to your whole body so it can function. Blood pressure vs. heart rateBoth of these have to do with your heart, but they’re two different things. Blood pressure is how powerfully your blood travels through your blood vessels. Heart rate is the number of times your heart beats in one minute. An increase in heart rate doesn’t mean your blood pressure is going up, too. The only way to know your blood pressure is to measure it with a blood pressure cuff and gauge. Why blood pressure fluctuatesYour blood pressure doesn’t stay the same at all times. It changes based on what you’re doing. When you’re exercising or excited, your blood pressure goes up. When you’re resting, your blood pressure is lower. Your blood pressure can also change because of your:
Why blood pressure mattersHigh blood pressure — the “silent killer” — usually has no symptoms. It can damage your heart, kidneys and brain before you know anything is wrong. High blood pressure is a major risk factor for cardiovascular disease. Without treatment, high blood pressure can cause: Who is at risk of getting high blood pressure?Your risk of high blood pressure is higher if you:
When is blood pressure checked?Your healthcare provider should check your blood pressure at every annual checkup if your blood pressure is normal. If your blood pressure readings are high at your appointments, your provider may ask you to check your blood pressure at home anywhere from several times a day to once a week. You should take blood pressure readings at the same time of day each time. You can take two or three readings one after the other, as long as you wait one minute before the next one. When you’re done, figure out the average of the two or three readings you took. Your provider may ask you to wear a blood pressure monitor for 24 hours. The monitor is usually set to take blood pressure every 15 to 30 minutes while you do your normal activities. What treatments are available for patients with high blood pressure?High blood pressure is a major risk factor for cardiovascular disease. Without treatment, you can have a transient ischemic attack (TIA) or stroke, heart attack, enlarged heart, heart failure, peripheral vascular disease (such as poor circulation and pain in your legs), aneurysms, kidney disease, and broken blood vessels in your eyes. Treatment includes making changes recommended by your healthcare provider. Diet and lifestyle changes:
Medications and follow-up care:
Your doctor may ask you to record your blood pressure at home. Follow your doctor’s instructions for recording your blood pressure.
To measure your blood pressure manually, your provider will:
You or your provider can use a blood pressure monitor to check your blood pressure automatically. What should I expect after the blood pressure test?If you’re nervous when you go to your appointment, you could have a false high blood pressure reading. This is called “white coat syndrome.” If this happens, your healthcare provider may ask you to use a blood pressure monitor to check your blood pressure throughout the day. You can bring a record of your blood pressure readings to your appointments. The cuff around your arm gets very tight when it’s inflated for a blood pressure measurement. However, it’s only tight for a short time before it gets comfortable again. Blood pressure readings tell your doctor if your blood pressure is normal. Your blood pressure reading has two measurements:
Providers give the measurements as millimeters of mercury (mm Hg). They started using these measurements when instruments to measure blood pressure contained mercury. What is normal blood pressure?Normal blood pressure is <120/<80 millimeters of mercury. Elevated blood pressure is 120-129/<80 millimeters of mercury. People with blood pressure readings in this category can develop worse blood pressure if they don’t do something to improve it. What blood pressure is too high?If your top number is ever 180 or higher and/or your bottom number is ever 120 or higher, get emergency medical treatment or have someone take you to the hospital right away. This is a hypertensive crisis. During a hypertensive crisis, you may experience: Higher blood pressure ranges mean you may have stage 1 or 2 hypertension (high blood pressure).
When your blood pressure readings are in stage 1 or stage 2, your provider will ask you to make lifestyle changes and take blood pressure medicine. What blood pressure is too low?A reading below 90/60 millimeters of mercury is a low blood pressure reading. This can be a normal reading for some people who always have low blood pressure. For other people, low blood pressure means something’s wrong. They may not have enough blood flowing to their major organs. Which blood pressure number is more important?Your healthcare provider can use the top or bottom number to diagnose you with high blood pressure. However, they usually focus more on the top number as a risk factor for heart disease if you’re older than 50. As you get older, the top blood pressure number rises because your arteries get stiff and collect plaque (fat and cholesterol) over time. When should I know the results of the blood pressure measurement?You’ll know your blood pressure reading right away, but your provider needs two or more readings (on different days) to determine if you have high blood pressure. They may make another appointment to check your blood pressure again on another day. When should I call my doctor?Contact your healthcare provider if your blood pressure reading at home is lower or higher than normal. Call 911 if your reading is 180/120 millimeters of mercury or even if only one of those numbers is that high. A note from Cleveland Clinic Even though you may not feel any symptoms, your blood pressure could be high. It’s important to check your blood pressure regularly so you know if you’re in the normal range. If you have high blood pressure, keep taking the medications your provider prescribed. Don’t stop or start taking them without talking to your provider. Blood pressure medication doesn’t keep working after you stop taking it. Keep all follow-up appointments so your provider can monitor your blood pressure, make any needed changes to your medications and help control your risk of cardiovascular disease.
