When choosing a blood pressure monitor, the American Heart Association recommends an automatic cuff that fits the upper arm. The AHA recommends consulting the Dabl Education Trust list of devices tested, validated and approved by one of three agencies. The A&D UA-651 and iHealth BP5 are on the Dabl list.
There are many devices on the Dabl Education Trust list, and it includes units for the wrist and upper arm. However, consumers should avoid wrist and finger monitors due to the inaccurate readings they provide, the American Heart Association indicates. When selecting a device for use on pregnant women or the elderly, it needs to have validation for the special use. The device must also provide an appropriate-size cuff.
