Validation of two blood pressure measurement devices according to the European Society of Hypertension International Protocol: the citizen CH-463E and the citizen CH-461C.

Objective: The validation of two new oscillometric blood pressure (BP) measurement devices according to the International Protocol (European Society of Hypertension).

Methods: Two trained observers measured BP in 33 patients with nine sequential same-arm measurements each, whereby five measurements with the mercury standard device alternated with four measurements with each of the test devices per patient. The resulting differences between the BP value read by the devices and the BP value obtained by the two observers were used for evaluation.

Trial of validation of two devices for self-measurement of blood pressure according to the European Society of Hypertension International Protocol: the Citizen CH-432B and the Citizen CH-656C.

Objective: Two devices for self-measurement of blood pressure, one at the upper arm (Citizen CH-432B) and one at the wrist (Citizen CH-656C), were evaluated according to the International Protocol of the European Society of Hypertension.

Design: The International Protocol is divided into two phases: the first phase is performed on 15 selected participants with five participants in three different blood pressure ranges. If the devices passed this phase, 18 additional participants selected on the basis of the same criteria as in phase 1 were included.
