Blood Pressure Device
When it comes to monitoring and taking your blood pressure, a blood pressure device will be used. However it is important to remember that while many different devices may go by varying names depending on the developer, they are all considered to be a sphygmomanometer. In its simplest form, the name roughly translates to a pulse pressure meter. This device was originally developed back in the late 1800’s and other than the digital ones available today, has not changed much in design. This is because the sphygmomanometer is the gold standard for the blood pressure monitoring. The digital blood pressure device works on the oscillometric method. They handle their measurements by focusing on the MAP or mean arterial pressure. Once this pressure measurement has been made and before it shows you the results, it will then perform a series of calculations to determine what the systolic and diastolic pressures actually are. However for persons with varying conditions, the digital blood pressure device will not be accurate. These conditions can include things like preeclampsia, arrhythmia, arteriosclerosis, pulsus paradoxus as well as pulsus alternans. These digital devices also come in many different forms to choose from. While they are all intended for home, or at least non-medical facility use, some are not portable. For example, the non portable type of electronic blood pressure device would be that of the ones you would see in a pharmacy. You then have the portable ones like the wrist monitor which rather than pulling the pressure from the upper arm at the level of the heart, it gets it from the wrist. You also have the digital finger monitor which uses two pressure pads to restrict blood flow. All of these digital blood pressure devices are based on the mean blood pressure and they use a calculative equation in order to come up with the actual systolic and diastolic blood pressures.
