Why digital blood pressure monitor is more convenient?

Digital blood pressure monitor  can be divided into two types:  arm type and  wrist type. It has no pollution and is convenient to use. It does not need to use a stethoscope, and it can quickly and effectively measure the blood pressure and pulse. Just press the button, and inflation and deflation begin automatically. Then the measured results are displayed directly on the screen. The top of the screen is the contraction pressure, the above is the diastolic pressure, the next is the pulse. Because of the larger words, the elderly with poor vision can also see the results of their measurements.
