Finger Blood Pressure Monitors

Finger Blood Pressure Monitors – Which is the Better

Finger blood pressure monitors a system for blood pressure measurement that ascertains blood pressure indirectly by the oscillometric method at the user’s index finger. Finger measurement allows the system to be smaller and easier to use than systems using conventional upper arm measurement.

By using the oscillometric technique, the system according to the invention needs no microphone and so avoids the problems associated with microphone positioning. The system employs a rigid finger cuff with an inflatable inner bladder. The system extracts pulse signals transmitted via air pressure while simultaneously providing accurate pressure control.

Lumiscope Blood Pressure Monitors are hospital tested and clinically accurate ensuring you the highest level of quality and precision. A professional quality instrument, automatic inflation, touchpad control. Contains Monitor, built-in finger cuff, easy-to-read instructions, record log.

How Do You Check Your Blood Pressure with Your Fingers?

First, locate the artery below the thumb on the inside of your wrist and place two fingers there. Count how many times you feel your heartbeat over a 15-second period, and then multiply your count by four to get your resting heart rate. When you’re checking pulse by hand, you’re looking for more than just a number.

Background and Objectives of Finger Blood Pressure Monitors

Automated finger blood pressure devices are marketed to consumers as accurate devices to monitor blood pressure. Our study compared the accuracy of those devices to plain vital sign cuffs.

Middle fingers are most commonly used but little research is available on inter-digit differences in pulse optometry measurements.

Methods of Finger Blood Pressure

Three models were purchased and tested against standard cuff measurement. With the patient relaxed and seated for at least 5 minutes, cuff measurement was performed. The vital sign was then measured by the three-finger devices in quick succession.

Results of Finger Blood Pressure Monitors

No statistically significant correlation was shown between cuff measurement and therefore the finger device measurements.

How to Buy the Best Monitor for You

Pick a top-scoring model that has the features you need and that will make testing easier for you. For example, some models allow you to store readings for quite one user. All the models we recommend are rated Excellent for accuracy, but there are other factors to think about, too. Follow these tips to help you select the best monitor for you:

Check the Fit

Make sure the vital sign monitor you select features a cuff that matches the circumference of your upper arm or wrist. (Use a tape measure to be certain.) Using a cuff that’s the wrong size can result in inaccurate readings. Most of the arm models we tested have two cuffs or a cuff which will be adjusted to suit most of the people. Wrist models also fit most people.

Consider Cost

The recommended models in the ratings (available to members) were priced from $40 to $100. But shop around. And determine whether your insurance covers vital sign monitors.

Choose One That’s Easy to Use

The display on the monitor should be easy to read. The buttons should be large and intuitive. The directions for using the cuff and operating the monitor should be clear.

Select the Features You Need

There are many features to seem for when selecting a vital sign monitor. Here are some to consider: irregular-heartbeat detector, risk-category indicator, multiple user memories, multiple cuffs, memory download capability, large-digit display, and data averaging function.

To monitor your blood pressure accurately, you will need to make sure you use the right technique – and the right monitor.

Choosing a monitor

Whichever home blood pressure monitor you go for, it’s vital that you ensure it is labeled as being ‘clinically validated’ by the British Hypertension Society. This is a guarantee that the equipment has been thoroughly tested and that you can rely on the accuracy of its readings.

Here are some other pointers:

  • You may find it easier to use a fully automated or digital monitor.
  • For consistently accurate readings, choose a machine that measures vital signs within the upper arm instead of a finger or your wrist.

Prices vary and you will pay more for equipment with more features – such as a built-in memory. However helpful these additional features may seem, remember they are not absolutely necessary. You just need a good machine that you can afford, and pen and paper to take your readings.

Monitor maintenance

As with all equipment, your vital sign monitor needs maintenance. Send it away to the manufacturer for recalibration every two years to guarantee the continued accuracy of your results.

Cuff size matters

Machines measuring vital signs within the upper arm accompany a cuff you wrap around your arm, and therefore the wrong sized cuff will produce an incorrect reading.

Place the cuff half way between your shoulder and elbow.

Before buying, measure your upper arm. If its circumference is 18-22cm, you need a small cuff; for 22-32cm use a medium sized one. Bigger arms require a large cuff.

Bear in mind that most monitors are supplied with a medium cuff, and you may have to buy a different size separately.


The weighted accuracy of finger arterial pressure measurement among these studies comprising a total of 1031 subjects was −0.8±11.7 mmHg [range −48 to 30 mmHg] for systolic pressure, −1.6±8.5 mmHg [range −20.1 to 18.5 mmHg] for mean pressure and −1.6±7.7 mmHg [range −13.4 to 25 mmHg] for diastolic pressure (Fig.

Studies have shown that using too small of a vital sign cuff can cause a patient’s systolic vital sign measurement to extend 10 to 40 mmHg. Blood Pressure Cuff Used Over Clothing1,3,4 – When having your vital sign measured, the cuff should be placed directly on your arm.
