Why Does My Blood Pressure Vary Throughout The Day

Blood Pressure Measurement: How to Check Blood Pressure Manually

You may have heard the term circadian rhythm. If so, you know this is not a beat to keep on the dance floor. It is a biological cycle your body follows. As defined by the National Institute of General Medical Sciences, âCircadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment.â As your body cycles through this rhythm each day, responding to both internal and external stimuli, your blood pressure is affected.

The study of these important rhythms, known as chronobiology, was founded by Franz Halberg. His work in this field has helped identify abnormal rhythms in day-night blood pressure readings.Keeping the Beat of Blood PressureFollowing this chronobiological rhythm, your blood pressure is normally higher during the daytime and lower at night, during sleeping hours. Hereâs the problem. People with high blood pressure often donât experience this night time dip. This lack of a lowering of blood pressure at night is referred to as non-dipping.Whatâs the big deal? Heart attack and stroke have been found to be associated with non-dipping. Your blood pressure stays elevated, and your body is not in the relaxed state it should be during rest.

How To Check Your Blood Pressure At Home

Follow expert advice and a step-by-step video to ensure youre getting the most accurate numbers.

To check your blood pressure, you just switch on a portable monitor and put a cuff on your arm, right? Actually, theres a little more to it than that, says cardiology nurse practitioner Tiffany Luke.

Its important people properly and closely monitor their blood pressure as this is how we determine therapy, Luke explains.

First things first: What is high blood pressure?

High blood pressure, medically known as hypertension, can be caused by weight gain, alcohol and salt intake, older age and/or a family history. According to the CDC, about 75 million American adults have high blood pressure. Referred to as the silent killer, its not a reading that should be taken lightly. Controlling or lowering blood pressure can help prevent or delay high blood pressure complications including heart attack, stroke, atrial fibrillation and chronic kidney disease, says Luke.

But luckily, the conditions treatable. Patients with high blood pressure may only need to make heart healthy lifestyle changes such as a low sodium diet and weight loss for improvement or if necessary be started on medication.

The American Heart Association defines stage 1 hypertension as a blood pressure consistently over 130/80.

What Is Blood Pressure Testing

Blood pressure is usually measured in a seated position, with an arm resting in a bent position so it is at the same level as your heart. Your upper arm should be bare, with your sleeve comfortably rolled up.

Blood pressure readings are measured in millimeters of mercury and are given as two numbers. For example, 110 over 70 .

  • The top number is the systolic blood pressure reading. It represents the maximum pressure exerted when the heart contracts.
  • The bottom number is the diastolic blood pressure reading. It represents the minimum pressure in the arteries when the heart is at rest.

High Blood Pressure Treatment

Our providers may recommend lifestyle changes to lower your blood pressure, such as:

  • eating a healthy diet that is low in fat, cholesterol, and sodium
  • increasing exercise and physical activity
  • losing weight if you are overweight or obese, and maintaining a healthy weight
  • quitting tobacco if you currently smoke or chew tobacco and
  • limiting how much alcohol you drink.

Choosing A Home Blood Pressure Monitor

Blood Pressure

The American Heart Association recommends an automatic, cuff-style, bicep monitor.

  • Wrist and finger monitors are not recommended because they yield less reliable readings.
  • Choose a monitor that has been validated. If you are unsure, ask your doctor or pharmacist for advice or find options at validatebp.org.
  • When selecting a blood pressure monitor for a senior, pregnant woman or child, make sure it is validated for these conditions.
  • Make sure the cuff fits measure around your upper arm and choose a monitor that comes with the correct size cuff.

Apps To Track Your Blood Pressure

Although there are apps that promise to check your blood pressure without using equipment, this isnt an accurate or reliable method.

However, there are apps that can help you track your blood pressure results. This can be helpful in identifying patterns in your blood pressure. Your doctor may use this information to determine if you require blood pressure medications.

Some examples of free apps to monitor blood pressure include:

  • Blood Pressure Monitor Family Lite for iOS. With this app, you can enter your blood pressure, weight, and height, as well as track the medications you take.
  • Blood Pressure for Android. This app tracks your blood pressure and features several statistical and graphical analysis tools.
  • Blood Pressure Companion for iOS and macOS. This app allows you to track your blood pressure as well as view graphs and trends on your blood pressure readings across several days or weeks.

These apps can help you quickly and easily track your blood pressure readings. Measuring your blood pressure regularly on the same arm can help you most accurately track your blood pressure readings.

Measuring Your Blood Pressure

How to: Measure Blood Pressure
  • 1Inflate the cuff.XResearch source Rapidly squeeze the pump bulb until you no longer hear the sound of your pulse through the stethoscope. Stop once the gauge reads 30 to 40 mmHg above your normal blood pressure.
  • If you do not know your normal blood pressure, inflate the cuff until the gauge reads between 160 to 180 mmHg.
  • 2Deflate the cuff. Open the airflow valve by twisting the screw counterclockwise. Let the cuff deflate gradually.
  • The gauge should fall 2 mm, or two lines on the gauge, per second.
  • 3Listen for the systolic reading. Note the measurement on your gauge at the precise moment you hear your heartbeat again. This measurement is your systolic reading.

    What Is Blood Pressure And How Is It Measured

    The heart supplies the organs and tissues of the body with blood. With every beat, it pumps blood into the large blood vessels of the circulatory system. As the blood moves around the body, it puts pressure on the walls of the vessels. Blood pressure readings are made up of two values:

    • Systolic blood pressure is the pressure when the heart beats while the heart muscle is contracting and pumping oxygen-rich blood into the blood vessels.
    • Diastolic blood pressure is the pressure on the blood vessels when the heart muscle relaxes. The diastolic pressure is always lower than the systolic pressure.

    Blood pressure is measured in units of millimeters of mercury . The readings are always given in pairs, with the upper value first, followed by the lower value.

    So someone who has a reading of 132/88 mmHg has a

    • systolic blood pressure of 132 mmHg, and a
    • diastolic blood pressure of 88 mmHg.

    What Do The Results Mean

    Your results, also known as a blood pressure reading, will contain two numbers. The top or first number is the systolic pressure. The bottom or second number is the diastolic pressure. High blood pressure readings are also labeled by categories, ranging from normal to crisis. Your reading may show your blood pressure is:

    Blood Pressure Category
    and 120 or higher

    If youâve been diagnosed with high blood pressure, your provider may recommend lifestyle changes and/or medicines to control your blood pressure. Your provider may also recommend that you regularly check your blood pressure at home with an automated blood pressure monitor. An at-home blood pressure monitor usually includes a blood pressure cuff and a digital device to record and display blood pressure readings.

    Home monitoring is not a replacement for regular visits to your provider. But it can provide important information, such as whether treatment is working or your condition may have worsened. Also, home monitoring may make the test less stressful. Many people get nervous about getting their blood pressure taken at a providerâs office. This is called âwhite coat syndrome.â It can cause a temporary rise in blood pressure, making the results less accurate. For more information about home monitoring of blood pressure, talk to your provider.

    It is best to measure blood pressure when you are relaxed and sitting. Blood pressure is usually measured by wrapping an inflatable pressure cuff around your upper arm.

    Blood pressure is recorded as two numbers, such as 120/80. The larger number indicates the pressure in the arteries as the heart pumps out blood during each beat. This is called the systolic blood pressure.

    The lower number indicates the pressure as the heart relaxes before the next beat. This is called the diastolic blood pressure. Both are measured in units called millimetres of mercury .

    What If Im Taking Medication Does This Affect When I Should Check My Blood Pressure

    Yes. If taking high blood pressure medication, your blood pressure measurements should coincide with your doses. The best time to check it is before you take your medication. It is at this point that the level of medication in your body will be at its lowest. This is known as a trough value. Measuring your blood pressure before you take the next dose will demonstrate how well the medication has been working.

    Another important variable to consider is symptoms. If you are experiencing a symptom of high blood pressure, it is a good idea to take a measurement then. Of course, if symptoms are severe, contact your doctor or seek immediate assistance.Common symptoms of high blood pressure include:

    • Intense headaches
    • Pounding in your chest, neck, or ears
    • Irregular heartbeat
    • Breathing issues

    Measuring your blood pressure while experiencing these symptoms can help determine if high blood pressure is the cause. It is also possible that your medication has lowered your blood pressure too much. A blood pressure reading during symptoms can also help determine if an adjustment to your medication is needed, either in dosage or time of day it is taken.
