As early as 1876 Marey began to study the oscillometric method of blood pressure measurement of blood pressure, but it was not until 1976 that Ramsey invented an instrument to determine mean arterial pressure using the oscillometric method. This was followed by the development of methods for estimating systolic and diastolic blood pressure. As the estimation methods were further refined, the more established oscillometric sphygmomanometer became available in 1991.
Unlike the benchtop mercury sphygmomanometer, which determines systolic and diastolic pressures by identifying the appearance and disappearance of the Koch sound. The oscillometric method of electronic sphygmomanometers senses pulse wave information during deflation or inflation and obtains systolic and diastolic pressure data through a complex series of conversions and calculations. During deflation, the blood flow in the arm artery goes from completely blocked to gradually returning to normal, and the pulse signal in the brachial artery goes from absent to present, and tends to increase and then decrease. The amplitude of this pulse signal is weak, but can be sensed, amplified by the pressure transducer of the sphygmomanometer and results in an envelope based on the change in cuff pressure and the change in pulse amplitude (figure below). Different manufacturers have their own specific procedures for calculating systolic and diastolic pressures, with the systolic-to-apical ratio ranging from 45% to 57% and the diastolic-to-apical ratio ranging from 74% to 82%.
What should I look for if I want to get more accurate blood pressure results?
Don't eat while your blood pressure is being taken
It is best not to eat or drink food, especially beverages or foods containing caffeine, before having your blood pressure measured, as these substances can raise your blood pressure and cause the results to be inaccurate.
Take multiple measurements
Many people tend to measure their blood pressure only once, thinking that the results are accurate even if they are measured only once, but this is not correct. It is better to take several measurements when taking blood pressure, and then come up with an average of the results to reflect the normal level of your own blood pressure.
Pay attention to your posture when taking blood pressure
Generally, when measuring blood pressure on your own, you must pay attention to the posture of measuring blood pressure, and it is best not to have clothes on your arms, because blood pressure monitors are usually electronic, and if there are clothes on your arms will make the measurement result be affected, resulting in the consequences of inaccurate blood pressure values.
It is also advisable to tie the blood pressure monitor tightly when taking blood pressure measurements, as it can affect the accuracy of the results if it is too loose. When measuring blood pressure, it is best to make your arm and heart at the same level and at a similar height in order to get a more accurate result.
