Accuracy of automated finger blood pressure devices.
OBJECTIVE
Automated finger blood pressure devices are marketed to consumers as accurate devices to monitor blood pressure. Our study compared the accuracy of these devices to standard blood pressure cuffs.


METHODS
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 blood pressure was then measured by the three finger devices in quick succession.


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


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