Calibration of a Wrist Cuff Blood Pressure Device, According to the AAMI/ESH/ISO Universal Standard

Inclusion Criteria: * Adults ≥ 19 years of age (minimum 30% male/female) * Wrist circumference between 13.5 cm. - 23 cm. (5.3 in. - 9.1 in.): Specifically for this test device, the wrist size of the consented participants will be distributed accordingly for a Gaussian distribution: Lowest Octile: ≥ 13.5cm to \< 14.7cm Lower Quarter: ≥ 13.5cm to \< 15.9cm Lower-Middle Quarter: ≥ 15.9cm to \< 18.3cm Upper-Middle Quarter: ≥ 18.3cm to \< 20.7cm Upper Quarter: ≥ 20.7cm to ≤ 23.0cm Highest Octile: ≥ 21.9cm to ≤ 23.0cm ● Willing to volunteer to participate and to sign the study specific informed consent form Exclusion Criteria: * Wrist circumference less than 13.5 cm. (5.3 in.) or greater than 23 cm. (9.1 in) * Hand or body tremors * Irregular heart rhythm (bigeminy, trigeminy, isolated ventricular premature beat (VPB), atrial fibrillation) * Korotkoff sound K5 not audible * Pregnant * A musculoskeletal disorder that prevents a non-invasive device to be inflated/deflated on the arm * Unwilling to volunteer to participate and to sign the study specific informed consent form
