ELECTRONIC SPHYGMOMANOMETER, Microlife VSA
Definition
Handheld semi-automatic oscillometric device to measure blood pressure in people aged 12 years or older.
An electronic device, typically digital, designed to noninvasively measure blood pressure using a manually-inflated cuff that fits around the arm. It displays current heart rate in addition to systolic and diastolic blood pressures; it has memory to store blood pressure values and a visual warning system if blood pressure exceeds pre-set limits. This device is designed to be portable (e.g., hand-held or carried in a pouch).
