That's because blood pressure may change based on different factors, including pain, temperature, physical effort and even a doctor's visit.
So how can you avoid these potential wrong positives and false negatives? Do the DIY test.
If you can not imagine yourself sitting in your kitchen table manually pumping up blood pressure slap, do not worry. The latest crop of over-the-counter monitors is wireless, digital and easier than ever to use. Here's what you need to know before buying one.
How does wireless blood pressure monitor?
Every time your heart is funny, it warms blood into your circulatory system, which puts pressure on the walls of your blood vessels. Blood pressure pressures usually measure the strength of this pressure in millimeters of mercury (mmHg) using something called sphygmomanometer.
A sphygmomanometer raises a scissors wrapped around your finger, wrist or upper arm until the blood does not flow through the brachial or radial artery. When the air is slowly released from the slap, the blood flows through the arteries again, creating a pounding sound that can be seen with a stethoscope or an algorithm.
Your blood pressure cyst is the mentioned pressure reading when this sound starts to pound. Your diastolic blood pressure occurs when it stops.
Digital wireless blood monitor monitors will show your main unit results, in an accompanying smartphone app – where you can view graphs and trends and sync data using the additional apps like Apple Health – or both.
The measurement is written as two numbers. The top is your systolic blood pressure (the pressure when your heart beats). The bottom is your diastolic blood pressure (the pressure between the beats). A healthy blood pressure ranges from 90/60 to 120/80 mmHg.
Who are the wireless blood monitors for?
The American Heart Association (AHA) and other health organizations recommend that people with high blood pressure measure at home, a practice known as self-measured blood pressure (SMBP) monitoring or home blood pressure monitoring (HBPM).
Blood pressure increases and falls throughout the day but high reading (at least 130/80 mmHg) may indicate that your heart is prevented and working very hard, a condition known as hypertension . High blood pressure often has no clear signs or symptoms, so it's known as "silent killer." Over time it can increase your risk of heart attack, stroke and heart and kidney failure.
SMBP can assist in removing "white coat hypertension," where a person's blood pressure is high in the doctor's office but is normal in daily life, and masked hypertension, if where the human blood pressure is normal at the doctor's office but elevated in daily life.
"Transmission of blood pressure as part of every office visit does not matter, and the worst, can lead to inferences about a person's hypertension status that is not right," says cardiologist Erica S. Spatz, MD, clinical investigator at Yale New Haven Health Hospital Center for Results and Research Results. "Ideally we use home blood pressure readings to screen for and monitor hypertension. These readings are further indicated by the true status of a person's hypertension and are more closely related to the outcomes which we value, especially heart disease, stroke and kidney disease. "
It can also inspire a stronger sense of responsibility for your health and better control over your situation. Research shows that adults with hypertension who monitor their blood pressure at home (with or without additional support) are more likely to reduce their readings compared to standard care.
But you do not have to have hypertension to benefit from using wireless monitors blood pressure. They may also see hypotension, or chronically low blood pressure (below 90/60 mmHg, though it may vary from person to person). In some people, hypotension can be a problem. In others, it may indicate that something more serious, such as heart failure or severe infection, occurs, especially if it is accompanied by symptoms such as nausea, fever or nausea.
"To the elderly or to the weak, we are even more concerned about the collapse," says Spatz. "So it's important to check low blood pressure, especially in standing up."
If you have high or low blood pressure, SMBP monitoring can help you and your doctor catch issues early and monitor if any medication or lifestyle is working, while everyone is returning to office visits.
What if I do not have high or low blood pressure?
People who are healthy but at a higher risk of hypertension and cardiovascular disease, such as those with a family history of early hypertension or women with a history of preeclampsia during pregnancy, can be also benefit from the SMBP tests. "Home blood pressure monitoring can sometimes give an early window to high blood pressure, giving higher risk people the feedback they need to prevent the onset of hypertension," says by Spatz.
Totally healthy? Occasional SMBP can still help. "Knowing how your blood pressure response during stress or sleep deprivation can provide vital mental-minded connections, and may motivate you to take a more holistic approach to your health in cardiovascular, "says Spatz.
Just one caveat: Some people do not get accurate blood pressure readings using these devices due to illness, birth defects or conditions like an irregular heartbeat, talk to your doctor about whether you are right for SMBP.
What to look for in the blood pressure wireless monitor
Wireless blood pressure monitor is extensively without prescription, but it pays to choose.
The AHA recommends only the use of upper-oscillometric upper arm devices that have successfully passed verification certificates, according to a 2019 scientific statement in the medical journal Hypertension. (Oscillometric devices automatically detect and examine pulse waves as opposed to relying on someone to listen to a stethoscope.)
Wrist-based monitors, though convenient, are not recommended. Studies show that they are more likely to produce improper readings, both because they are highly sensitive to the body position (leading to people who use them wrong) and because the Wrist arteries tend to be narrower and less complicated under the skin.
Both the British and Irish Hypertension Society and Dabl Educational Trust website maintain a list of validated blood-pressure monitors, including wireless upper-arm cuff oscillometric devices. You can also pick up your device at your doctor's office and compare its readings with your physician's picks. (If you purchase a monitor for a senior, a pregnant or a child, make sure that it is also valid for this particular use.)
After the accuracy, the size of the slap is important. Circles that are too big or too small can make inaccurate readings. AHA recommends the following sizing guidelines that are contained in circumference, but you may also get help from a doctor or pharmacist that applies to you for one.
Arm Cuff Measurement Guidelines
|Arm Circumference||Standard Size Size|
|22-26 cm||Small adult|
|35-44 cm||Big old man|
typical price range from approximately $ 30 to $ 100, although a higher price tag does not necessarily equal to higher quality . If you want to spend a little more for extra bells and whistles (your cost insurance can help), keep an eye on these useful features:
- An automatic monitor. Find a device that allows you to start a reading at the touch of a button.
- Customizable reading. Some devices will have three consecutive readings and will automatically calculate the average, according to AHA recommendations.
- A digital readout. If it is displayed on the device or in an accompanying app, the measurement should be clear and easy for you to read.
- Sharing. If you manage an existing condition, the devices that store your readings, including the dates and times they took and you can easily allow them to export or share them in Your doctor is best.
How to use a blood pressure wireless monitor
"Checking your home blood pressure should not be heavy," says Spatz. "I recommend that patients with strong hypertension take a slap in the week before their appointment and measure twice a day so that we can use these measurements to guide our management. Unless we are working actively changes in the treatment plan, patients may remove the cuff until the next visit. "
You should talk to your doctor about what routine is right for you, but in general, here are some best practices:
- Measure your blood pressure twice a day. Perfectly at the same time each day. Take the first measurements in the morning after going to the bathroom but before you eat, exercise, drink any caffeinated or take medication. Get the second measurement before dinner or at least 30 minutes after eating, alcohol, caffeine or tobacco. Again, use the bathroom first, because a whole bladder may slightly increase your blood pressure.
- Get comfortable. You should be seated in a chair, supported behind your legs and not longer the feet are flat on the floor.
- Position your arm properly . Always use the same arm to bring your blood pressure (If one arm tends to make a higher reading, use that one). Rest it on a flat surface, such as a table, with your upper arm at the heart level (prop up it on a cushion if it is too low). The slings should be packed tight, but not tight, around the naked skin of your upper arm, directly above the bend in your elbow.
- Sit quietly. Take five minutes to get calm and relaxed in this position. Try not to think about anything that is stressful.
- Get two to three reading . Keep your body in the same position and try not to talk while your device is reading. If your device does not automatically record your result, write it with time. Leave the slap in the rotating area, wait one to two minutes and then take another reading. Repeat this process a third time and then average the results. Your blood pressure is normal to be less than five in the home than in the doctor's office.
When you see a doctor about your blood pressure
"Blood pressure below 120/80 mm Hg is perfect," says Spatz. But your doctor will discuss what is the appropriate number for you.
If you get a single reading higher or lower than that number, do not worry. Make additional reading using the guidelines above.
If your measurements have suddenly grown above 180/120 mm Hg, the AHA recommends waiting five minutes and re-testing. If your blood pressure is too high, contact your doctor immediately.
If your blood pressure is higher than 180/20 mm Hg and you are experiencing symptoms such as chest pain, back pain, lack of breathing or vision change, call 911.
If your blood pressure is lower than normal and you experience dizziness, illness, nausea or anything outside of the ordinary, contact your doctor. "While monitoring blood pressure at home can be done independently with some simple rules about what is normal, it is still important to have a trusted doctor or nurse available to help interpret readings," says by Spatz. "Blood pressure varies throughout the day, and there may be spikes or dips in blood pressure that may or may not be clinically significant."
