BACKGROUND AND OBJECTIVES: 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.
