Validation of a non-mercury digital auscultatory device with manual pressure registration (PMS Mandaus).

Objective: To assess the clinical accuracy of a non-mercury digital auscultatory device (PMS Mandaus) with manual pressure registration in an adult population.

Methods: The accuracy of the device was assessed by predefined criteria (European Society of Hypertension protocol) in 33 study participants recruited from among patients and staff in a teaching hospital. A series of same-arm sequential blood pressure measurements were taken: first, two observers taking simultaneous mercury readings, followed by a reading with the device.
