Take your blood pressure at the same time every day. Take at least two readings, 1 or 2 minutes apart.
Don't check your blood pressure too often.
Some people find that they become worried or stressed about small changes in their readings if they take them too often. Worrying can also raise your blood pressure in the short term, making your reading higher than it should be.
At the beginning, measure your blood pressure at least twice daily. Take it first in the morning before eating or taking any medications. Take it again in the evening. Each time you measure, take two or three readings to make sure your results are the same.
The international BP guidelines for the use of home BP [12–14] have stated that when a series of readings is taken, a minimum of two readings should be taken at intervals of at least 1 min, and the average of those readings should be used to represent the patient's blood pressure.
Everyone's blood pressure rises and falls many times during the course of a single day, sometimes even within minutes. Many factors contribute to these changes, including physical activity, emotion, body position, diet (especially salt and alcohol intake), and sleep deprivation.
Your first blood pressure reading will almost always be higher than the second due to a wide range of factors, both environmental and psychological. These factors include white coat syndrome, stress, and having a full bladder.
Blood pressure should be checked while seated after a few minutes of rest. Take at least two readings a minute apart each time. Wait at least 30 minutes after having caffeine, alcohol, smoking, or exercising before taking your blood pressure.
A cuff that is too snug or too loose on the mid-upper arm can lead to greatly exaggerated blood pressure measurements, results of a community-based study show.
Ignore the first day's readings altogether, because they might not be accurate as you're not familiar with your monitor yet. At the end of the week you will have a useful picture of what your blood pressure is normally like.
Still, you can make lifestyle changes to bring your blood pressure down. Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
As there is no obvious physical effort that might explain this variability, a psychologic mechanism has been postulated. Blood pressure has been shown to increase during talking, in normotensive young adults7,8 and in hypertensive patients.
With the arm straight and parallel to the body, blood pressure readings can be up to 10% higher than when the elbow is bent at a right angle to the body at the level of the heart, researchers found. The ideal position falls between those extremes, with the arm at heart level and the elbow slightly flexed. Dr.
Arm position
Dependency of the arm below heart level leads to an overestimation of systolic and diastolic pressures and raising the arm above heart level leads to underestimation. The magnitude of this error can be as great as 10 mm Hg for systolic and diastolic pressures.
A rise in blood pressure overnight to early morning has been linked to an increased risk of heart disease. An irregular blood pressure pattern could also mean that you have: Poorly controlled high blood pressure. Obstructive sleep apnea.
The bottom (second) number, diastolic pressure, is always lower since it reflects the pressure inside the arteries during the resting phase between heartbeats. As it turns out, both systolic and diastolic blood pressure are important.
Don't eat or drink anything 30 minutes before you take your blood pressure. Empty your bladder before your reading. Sit in a comfortable chair with your back supported for at least 5 minutes before your reading. Put both feet flat on the ground and keep your legs uncrossed.
Normal: Less than 120/80. Elevated: Systolic between 120-129 and diastolic less than 80. High blood pressure (hypertension) Stage 1: Systolic between 130-139 or diastolic between 80-89. High blood pressure Stage 2: Systolic 140 or higher or diastolic 90 or higher.
Normal blood pressure for most adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. Elevated blood pressure is defined as a systolic pressure between 120 and 129 with a diastolic pressure of less than 80.
Call 911 or emergency medical services if your blood pressure is 180/120 mm Hg or greater and you have chest pain, shortness of breath, or symptoms of stroke. Stroke symptoms include numbness or tingling, trouble speaking, or changes in vision.
If a cuff is too small or too large, errors in measurement can occur. Adding to inaccuracy are automated devices that have not been tested for accuracy, which can account for errors in systolic BP.
Conclusions. Single-arm measurements, compared to double-arm measurements, may underestimate the prevalence of hypertension. However, if double-arm measurements are unavailable, right arm is preferred for measurement of BP, especially in women.
But home blood pressure monitors aren't always as accurate as they should be. "Home blood pressure monitors may be inaccurate in 5% to 15% of patients, depending on the threshold for accuracy used," according to Dr.
When it comes to blood pressure, one reading may not be enough. Forty-six percent of Americans have high blood pressure, but studies show when it's taken twice at your doctor's office - with at least one minute in between - the second reading is typically lower and a more accurate measurement.
