A&D UM-101 - Medaval

Description:

The A&D UM-101 is a desk (tabletop) manually-operated mercury-free sphygmomanometer. Its blood pressure measurement technology has been proven to be accurate, with a 1-star Medaval rating. Blood pressure measurements are taken from the upper arm. It is intended for professional use. This device has been discontinued by the manufacturer but may be available through certain outlets.

Assessment:

The technology used in the A&D UM-101, to measure blood pressure, has passed in four clinical validation studies, between general and pregnancy populations, according to recognised standard protocols, as published in peer-reviewed publications.

Recommendations:

	Accuracy Assessment	Recommendation	Basis
BP	Medaval	★ Recommendation	Older clinical validation; older protocol; multiple clinical validations
