Description:

The Huawei Watch D2 (LCA-B11) is a wristwatch style automatic blood pressure monitor. Its blood pressure measurement technology has been proven to be accurate, with a 3-star Medaval rating. Blood pressure measurements are taken from the wrist. It is intended for self-measurement ABPM.

Assessment:

The technology used in the Huawei Watch D2 (LCA-B11), to measure blood pressure, is among the best rated for accuracy by Medaval Ltd. It has passed in two clinical validation studies, between general and specific populations, according to recognised standard protocols, as published in peer-reviewed publications.

Recommendations:

	Accuracy Assessment	Recommendation	Basis
BP	Medaval	★★★ Recommendation	Recent clinical validation; recent protocol; multiple clinical validations
BP	Stride BP	Self-measurement for adults	Published evidence
