Description:

The Citizen CHU302 is an automatic blood pressure monitor. The accuracy of its blood pressure measurement technology has yet to be proven to MDR requirements. Blood pressure measurements are taken from the upper arm. It is intended for self-measurement and home use.

Assessment:

The technology used in the Citizen CHU302, to measure blood pressure, has been compared to a clinically validated device, but the results of the equivalence study have not been published and cannot be verified; nor can the protocol be checked for compliance with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.

Recommendations:

	Accuracy Assessment	Recommendation	Basis
BP	Medaval	None	Although equivalence to another device is claimed, this has not been tested to MDR requirements.
BP	Japanese Society of Hypertension	Self-measurement (Latest: 2016-2018, 2021-2022)	Unpublished equivalence to the Citizen CH-432B, by questionnaire

Validation Publications for Equivalent Devices:

Note: This is a provisional list, as equivalence according to EU Regulation 2017/745 (e.g. MEDDEV 2.7/1 rev 4) is not proven. Accordingly, these publications are not used in the assessment of star-ratings.
