Finger Blood Pressure Monitors

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 oximetry 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.

Conclusion of Finger Device

Patients should be cautioned that these devices may not be able to perform as they are marketed.
