Digital Blood pressure monitors for home use are most commonly found in three styles.
Automatic blood pressure monitors (arm-style) are the most popular and easy to use home blood pressure monitors. The technology is based on the "oscillometric method" - a non-invasive blood pressure determination. The term "oscillation" refers to the measure of vibrations caused by the arterial pulse. The cuff is first inflated until the artery is fully blocked. Then the monitor takes measurements while the cuff deflates. Blood Pressure monitors examing the pulsatile pressure generated by the arterial wall as it expands and contracts against the cuff with each heartbeat.
Manual blood pressure monitors (arm-style ) are commonly used in a doctor's office. While it is necessary to inflate the cuff manually with the inflation bulb prior to taking a reading, the reading of the blood pressure is automated. This eliminates the need for a stethoscope and provides you with a digital readout of blood pressure (systolic and diastolic) and pulse readings.
Wrist-style blood pressure monitors are all-in-one units that adjust to
fit around your wrist. Since there's no need to remove a jacket or sweater, they can be much quicker than upper arm models. The same cuff size can be used for most adults, because the diameter of the wrist is affected little by a persons weight, in comparison with the upper arm.
