Methods: Eighty-five subjects (aged ≥18 y) with arm circumferences between 24 and 43 cm were studied. Blinded, two-observer, mercury-based auscultation performed using a two-piece cuff chosen for upper arm size was used for reference measurements. Accuracy criteria 1 and 2 of the ISO standard were determined and Bland–Altman plots generated. Results: Sixty percent of the study sample was female and 42% had hypertension. Mean device-to-reference standard differences in SBP/DBP were 0.0 ± 6.2/−0.2 ± 6.3 for criterion 1 and 0.0 ± 4.8/−0.2 ± 5.8 for criterion 2. Conclusion: The BIOS BD240 passed the requirements of the American National Standards Institute/Association for the Advancement of Medical Instrumentation/ISO standard for both SBP and DBP and can be recommended for use.
