Automatic blood pressure (BP), the monitors are an integral part of any monitor vital signs in hospitals that are used in intensive care units, emergency rooms, and even apartments. The reason is very simple - During an ECG can give the appearance of electrical signals in the heart muscle, the oximeter can give the oxygen content of blood in the body, only the bp monitor actually able to measure the real effectiveness of the heart pumps blood into the system.
The importance ofBlood Pressure Measurement
In other words, both the ECG and pulse oximeter may show normal values, but without the proper reading of blood pressure sensor, the cells of the body of the patient would still receive enough oxygen for normal operation. That would be the life of a patient without knowing that we are in danger.
Manual Blood Pressure Monitor
Before examining the operation of an automatic counter, look like a manual blood pressure measurementNIBP Monitor or Monitor, or high blood pressure bp monitor works. The instrument consists bp cuff, the air and pushes it slowly filled the main artery in the upper arm. The basic physics of the caliber reflects the interaction between the air pressure in the cuff and the pressure in the arteries. There are two basic pressure, systolic and diastolic artery. Systolic is the maximum pressure in the arteries and the diastolic is the minimumPressure.
The ease of use is as follows: when the air pressure is higher than the systolic blood pressure cuff, the cuff always pushes the artery until blood flow in the forearm is at a standstill, and there is no pulse, audible stethoscope. When the air pressure is lower than the diastolic blood pressure cuff, blood pressure keeps the artery in its natural size. Between these two pressures, followed by the expansion and contraction of the arteries of different bpartery and the pulsation is heard in the stethoscope on the arm.
Thus, increases in manual BP monitor, such as manual cuff blood pressure, the air pressure gradually until the diastolic blood pressure, pulse start to hear, and a further increase in cuff pressure get to you the higher the systolic blood pressure point where the pulse disappears.
How does an automatic blood pressure (BP) monitor to work?
The effect of an automatic digital bp monitorquite analogous to the operation of manual pressure gauge with some differences:
First, the speed, automatic digital bp monitors measure the systolic and diastolic blood pressure in the first step, while increasing the air pressure in the cuff. Secondly, the air in the cuff Digital BP will be provided by an electric pump instead of a hand pump. Thirdly, the pulse can not be observed by listening, but by the microphones or other sensorsTypes.
