There are two types of digital BP monitors: the upper-arm (shown above) and the wrist models (shown below). The upper-arm model has a cuff that is placed on the upper arm and is connected by a tube to the monitor that rests on a surface near the arm. The wrist model is smaller and the entire unit wraps around the wrist. Regardless of the BP monitor type, the measurement method is the same.
A digital blood pressure monitor uses an air pump to inflate a cuff surrounding an upper arm or a wrist with sufficient pressure to prevent blood flow in the local main artery. This pressure is then gradually released using a digitally-controlled solenoid valve until the moment that the blood begins to flow through the artery.
The blood pressure measured by a pressure sensor at this point determines the systolic pressure. Pulse rate is also sensed at this time. The measurement taken when the blood flow is no longer restricted determines the diastolic pressure. This complete measurement cycle is controlled automatically by the micro-controller.

2022-07-12 10:20:19 How do Blood Pressure monitors work?

A proper scientific name for a blood pressure monitoring device is sphygmomanometer.
For many decades, physicians used a manually inflated air-bladder cuff and a listening device called stethoscope to listen to arterial wall sounds. This is known as auscultatory method of measuring blood pressure. Using this method required some practice and it was typically performed by trained medical practitioners.
Recent advances in medical technology paved way for inexpensive, easy-to-use, digital BP monitors that anyone could use in the comfort of their homes without specialized knowledge or training.
A digital BP monitor uses an inflatable air-bladder cuff, a battery-powered air pump and a pressure sensor for sensing arterial wall vibrations  to measure blood pressure in an artery. This is known as oscillometric method. Open / Comment

Calatheas close their leaves at night ant RE-OPEN them on daylight.
The term "TO TURN A NEW LEAF" orginated from these Calatheas leaves.
A Calatheas is seen as a NEW BEGINNING and is called THE LIVING PLANT.
In fact, Calathea PURIFIES the Air and is good to have at home.
