Therefore the force at which the blood is pumped out of the heart is known as blood pressure. The normal blood pressure is 120/80 mm Hg, the first number simply means the time it took the heart to contracts and pump blood and the second figure means the time taken for the heart to relax and refill. Both are called the systolic and diastolic blood pressure respectively.
The medical device used in measuring the blood pressure is called sphygmomanometer and this has two types, the manual and the digital.
The digital can be used without the help of any person as it works automatically and pops up your result on the LCD screen.
But doctors and physician choose manual blood pressure monitor over digital one because it has been used for years and it’s very accurate. You will need the help of an expert or a medically oriented person to help you check your blood pressure with this manual monitor.
The manual sphygmomanometer can’t be used without the device called stethoscope. This is used to hear the sound of your pulse to know exactly your systolic and diastolic pressure.
The stethoscope can also be used to detect the heart rate, bowel movement and the activities going on in the lungs.
