When shopping for a home blood pressure monitor be on the lookout for a model that will give you the most accurate reading. Go for an upper arm as opposed to a wrist monitor (wrist monitors are very temperamental and prone to inaccuracy). Be sure, though, that the cuff is the right size for your arm.People who may have difficulty squeezing an inflator bulb should purchase a fully automatic unit. Individuals with visual impairment should look for a monitor with a large, easy-to-read digital display. An error indicator is also useful. Many individuals prefer to purchase a unit that has a memory feature, which ensures accurate recordkeeping. Once you have purchased your home blood pressure monitor, be sure to bring it along on your next doctors visit, so that it can be checked for accuracy.
