An electrically-powered device designed to noninvasively measure blood pressure using a self-contained software program that regulates automatic arm/wrist-cuff inflation and measurement cycles. It typically displays current heart rate and mean arterial pressure in addition to systolic and diastolic blood pressures; it may have memory to store blood pressure values and may sound an alarm if blood pressure exceeds pre-set limits. This device is designed to be portable (e.g., hand-held or carried in a pouch) and is often used for emergency services or home blood pressure monitoring.
