Frequently Asked Questions

Our most common questions regarding A&D products, A&D Companies and Blood Pressure in general. Let us know if you have a question not answered here. Contact us at either our Medical, Weighing or Corporate support.

My reading seems high. Is something wrong with the monitor?

Your cuff might be too small for you. A cuff that is too small yields a measurement that is higher than the correct blood pressure. Be sure to check that you are using the correct cuff size before taking your blood pressure. Please reference the section called "Select the correct cuff" in the instruction manual or see Question 4 to determine your correct cuff size. If your measurements still seem high, please consult your physician.

Why do my blood pressure readings vary so much during the day?

An individual's blood pressure varies greatly from day to day and season to season. Normally, blood pressure rises during work or play and falls to its lowest levels during sleep. The best way to get consistent readings is to monitor your blood pressure at least once a day, at the same time so that you can minimize the effect that external factors have on the reading.

Also please be sure to consult your physician immediately if you have any doubt about your readings. Should a mechanical problem occur, contact LifeSource.

Can a digital cuff work on an aneroid unit?

No, digital and aneroid units use different type cuffs. Digital cuffs have one hose and aneroid cuffs have two hoses.

How do I select the correct cuff size?

Using the correct size is important for an accurate reading. With your arm hanging at the side of your body, measure the circumference of your upper arm at the midpoint between shoulder and elbow. Based on that information, you can determine what size cuff would work for you using the chart below (also available in the instruction manual):

  • Small Cuff  6.3 - 9.4" (16-24cm) 
  • Medium Cuff  9.4 - 14.2" (24 - 36cm)
  • Large Cuff  14.2 - 17.7" (26 - 45cm)
  • Extra Large Cuff  16.5-23.6" (42 - 60cm)

Also please be sure to consult your physician immediately if you have any doubt about your readings. Should a mechanical problem occur, contact LifeSource.

I am told I need to use a large cuff, but I fit into a standard. Can I still use a standard cuff?

Although you fit into a smaller cuff, you need to use the correct one to ensure an accurate reading. If your cuff is too small, your blood pressure reading will be artificially high. If your cuff is too large, you may get a lower-than-actual reading.

Also please be sure to consult your physician immediately if you have any doubt about your readings. Should a mechanical problem occur, contact LifeSource.

What number should I set the pressure setting at on the Auto-Inflation (model UA-767) and Talking Auto-Inflation (model UA-767T)?

For the Auto-Inflation (model UA-767) and Talking Auto-Inflation (model UA-767T), you need to set the cuff inflation pressure switch to a number that is at least 30 mmHg higher than your expected systolic pressure.

For example, if you believe your blood pressure to be 140 (systolic) over 90 (diastolic) set the switch to 170.

What if I set it too high?

You will still receive an accurate reading, but your arm will be constricted longer and you may feel some discomfort.

What if I set it too low?

The cuff will automatically deflate and reinflate again to the correct pressure.

Also please be sure to consult your physician immediately if you have any doubt about your readings. Should a mechanical problem occur, contact LifeSource.

I have set the pressure to the correct level, but when I take my reading all that is displayed is ERR or ERR2. What am I doing wrong?

Although you may be sitting correctly, and have the pressure setting on the appropriate level, you must remain very still. The blood pressure monitor works by sensing vibration of blood as it moves under the cuff. Moving, talking and other causes of vibration may result in an error message. The symbols ERR or ERR2 mean that either you or the monitor moved during the reading.

What is A&D most noted for with their products?

Clearly a better value is the mantra we live by. Besides being known for quality and long-lasting performance, A&D is, by far, the telemedicine leader in our industry.

 

What Is High Blood Pressure?

High blood pressure (HBP) is a serious condition that can lead to coronary heart disease, heart failure, stroke, kidney failure, and other health problems.

"Blood pressure" is the force of blood pushing against the walls of the arteries as the heart pumps out blood. If this pressure rises and stays high over time, it can damage the body in many ways.

Overview

About 1 in 3 adults in the United States has HBP. HBP itself usually has no symptoms. You can have it for years without knowing it. During this time, though, it can damage the heart, blood vessels, kidneys, and other parts of your body.

This is why knowing your blood pressure numbers is important, even when you're feeling fine. If your blood pressure is normal, you can work with your health care team to keep it that way. If your blood pressure is too high, you need treatment to prevent damage to your body's organs.

Blood Pressure Numbers

Blood pressure numbers include systolic (sis-TOL-ik) and diastolic (di-a-STOL-ik) pressures. Systolic blood pressure is the pressure when the heart beats while pumping blood. Diastolic blood pressure is the pressure when the heart is at rest between beats.

You will most often see blood pressure numbers written with the systolic number above or before the diastolic, such as 120/80 mmHg. (The mmHg is millimeters of mercury—the units used to measure blood pressure.)

The table below shows normal numbers for adults. It also shows which numbers put you at greater risk for health problems. Blood pressure tends to go up and down, even in people who have normal blood pressure. If your numbers stay above normal most of the time, you're at risk.

Categories for Blood Pressure Levels in Adults (in mmHg, or millimeters of mercury)

CategorySystolic
(top number)
 Diastolic
(bottom number)
Normal Less than 120 And Less than 80
Prehypertension 120–139 Or 80–89
High blood pressure      
     Stage 1 140–159 Or 90–99
     Stage 2 160 or higher Or 100 or higher
