BP Kiosks

Card Catalog



Blood Pressure (BP) kiosks have been popping up everywhere: drug and retail stores, gymnasiums and even airports.  But according to a recent report from the US Food and Drug Administration (FDA), that convenience may come at the cost of unreliable BP results.





Recently, the FDA issued an advisory (see link above) covering the accuracy of BP results reported by these kiosks, citing that they often report inaccurate results due to the following limitations:


 Use of a one size cuff for all upper arm sizes
 Incorrect cuff placement on the upper arm

Incorrect body position during the BP measurement process


Hypertension isn't diagnosed solely based on one or two kiosk readings.  Inaccurate BP results can lead to a misinterpretation of results, thus kiosks users who need medical care might not seek it because they are misled by inaccurate results.


My Comments on Kiosks:


Since BP measurements are prone to errors, the bp Trax "Quad Plot" screen can help identify those errors by displaying the scatter or variability of your results.  Excessive BP variability is an indication of inaccuracy due to factors listed by the FDA and by not following proper BP measurement procedures.


Please read "Don't Forget to Rest" in the library for instructions on how to properly measure your BP.


If Resting BP Procedures are not followed, then the results from a kiosk, a personal BP monitor or a medical office must be considered only as a screening test for Hypertension.  To increase accuracy, Resting BP Procedures must be followed as stated in the link above.  Speaking from experience, there are No Shortcuts in the BP measurements process if increased accuracy is your goal.
