Indications for BP Surveilance
A home BP assessment allows patients to check their BP frequently. Obtaining a history of BP measurements over a specified period can provide your doctor with a better estimate of your true BP level. The best way to determine if you have high BP is to measure it several times a day for several months. Medical studies have shown that home measurements of BP are more reliable than in-office measurements. One study made the following observation:
The advantages of electronic checking have begun to be appreciated by epidemiologists, who have always been greatly concerned about the accuracy of clinical BP measurement and have paid much attention to the problems of observer error, digit preference, and the other causes of inaccuracy described. It has been argued that the ease of use of the electronic devices and the relative insensitivity to who is actually taking the reading can outweigh any inherent inaccuracy compared with the traditional sphygmomanometer method.1

Types of Monitors
There are several different types of BP diagnostic tools, but there are two main types that are in heavy use: manual and digital.
Manual or aneroid sphygmomanometer has three parts—gauge, inflatable cuff, and a stethoscope. The cuff inflates around the upper arm to cut off blood flow to the lower arm. While observing the gauge and slowly letting the air out of the cuff, note at what point on the gauge the blood flow begins to return to the lower arm by listening with the stethoscope (systolic pressure). Continue listening and note on the gauge when the blood flows smoothly (diastolic pressure).
There are two types of digital monitors--semi-automatic and fully-automatic. The less expensive semi-automatic versions use a manually inflatable cuff while the more expensive fully-automatic devices employ an automatic-cuff that inflates at the press of a button. The systolic and diastolic readings display on a screen.
Many medical facilities are switching over to digital because of their ease of use and accuracy. For home use, digital measurements dominate.
Accuracy of BP Devices
Manual devices provide accurate measurements for BP. The automatic device also provide accurate readings when used with the correct size cuffs. In-home assessment offers accurate BP readings and in many cases, are more accurate than office measurements by professional staff3.
How to Select the Best Blood Pressure Monitor FOR SALE
There are lots of home blood pressure monitors on sale. Many cost less than $100. These assessment devices do not require a prescription to purchase. Below is a breakout of the different types of BP devices and where they fit on a product selection continuum.
The size of the BP cuffs are essential. Cuffs that are too small can provide false high BP readings. Cuffs that are too large may falsely provide low BP results. The correct cuff size depends on arm circumference.
What is the function of a blood pressure checker?
BP results from your heart pumping blood throughout your body. As the heart pumps out, the pressure rises. As your heart muscles relax, the pressures lowers. The high-pressure cycle is the systolic measurement, and the low pressure is the diastolic measurement.
What is high blood pressure vs. hypertension?
High BP and hypertension are the same things. It means that the patient's systolic pressure is above 140 and/or diastolic pressure is above 90. Hypertension is the medical term for high BP.
What blood pressure indicates hypertension?
A BP measurement above 140/90 indicates hypertension. The chart below displays BP measurements and their corresponding medical diagnosis.
Which is worst, hypotension (low BP) or hypertension (high BP)?
According to the American Heart Association, doctors consider low BP to be dangerous if it causes symptoms. These symptoms include dizziness, fainting, dehydration, or shallow breathing. High BP, however, is a major risk factor for coronary heart disease and stroke. The American Heart Association indicates that 33% of adults have hypertension, contributing to nearly 7% of deaths annually.4
Which states have the highest and lowest hypertension rates?
West Virginia has the highest hypertension rate at 43.5%, and Utah has the lowest rate at 24.5%.5
