Blood pressure is a common concern among many of the people around the world. You can have either high or low blood pressure as early as mid-20s if you are not careful enough to watch for it. However, hypertension and hypotension normally occur during the golden part of your life. Now, you may wonder how it works to have the tendency to increase or decrease your blood pressure. There are actually many ways to do so. One is the use of a Sphygmomanometer. It is a device that measures the systolic and diastolic parts of the pressure of the blood.
There are actually three (3) kinds of Sphygmomanometers that are all used to gauge the human blood
pressure. The first type is mercury; the second type is aneroid, while the last type is digital.
• Mercury sphygmomanometer is also considered as the “gold standard” of all the other types
of this device. This device assesses blood pressure by means of the observation of the stature
of a line of mercury in the body. Once the column is made, errors of calibration are not likely
to take place to their exactness; they are over and over again compulsory during all clinical
tests of pharmaceuticals and medical institutions as well as for all clinical assessments in order
to determine the blood pressure more particularly to those who are high-risk patients as well as
• Aneroid sphygmomanometers (those that are mechanical kinds amid a dial) are in
widespread utilization among health care practitioners and medical experts. This kind of
sphygmomanometer requires calibration checks, which is nothing like other manometers.
Aneroid sphygmomanometers are though out to be more harmless than those that are
mercury based, even though cheap ones are not as much of precise in its results. The most
important reason of disappearance on or after calibration is perfunctory jarring. Aneroid
sphygmomanometers are mounted on the stands or walls and these are not at risk to this
• Digital sphygmomanometers make use of electronic calculations and oscillometric
measurements relatively than auscultation. This devise is likely to use automatic or manual
inflation. This devise is electronic that is why it is easy to work even without no preparation,
in addition to that, it can be able to use in raucous environments. This devise specifically
measures systolic and diastolic blood pressures by means of oscillometric detection as well as by
making use of a piezoelectric pressure sensor and other electronic parts counting but not limited
to a microprocessor. However, this device does not gauge systolic and diastolic blood pressures
in a straight line, per se, but analyze them as of the mean pressure as well as the empirical/
statistical oscillometric parameters. A good number of medical instruments as well put on view
the pulse rate of the body. Digital sphygmomanometers and other instruments could make use
of a cuff placed, in order of precision and converse order of being portable and expediency, in
the region of the upper arm, a finger or the wrist.
