Blood pressure – the force with which the ejected during cardiac contraction, the blood presses against the walls of blood vessels. It is a kind of indicator of the quality of circulation – it reflects that there is enough nutrients and oxygen getting to the organs.

The expectant mother needs to know what pressure is considered normal and what requires treatment. You can perform the measurements independently. For this you will need a special device – a tonometer. There are several varieties of blood pressure monitors:
- mechanical is the most accurate, but its use requires some skill;
- automatic, including carpal (the easiest to use, but the result can be a big error).
The sphygmomanometer consists of a cuff, a pressurizing device, the valve body of the graduate and monitor or a scale with tick marks. First, air is pumped into the cuff using the compression of the pears by hand or automatically measure approximately to the level of 200-220 mm Hg. article, then slowly produced a special valve.
Automatic and semi-automatic machines show the result on the monitor. Mechanical blood pressure monitor also has a stethoscope – which measures have to attach the membrane to the elbow crease and through the headphones to catch the beginning and the disappearance of the bumps. Blood pressure at the moment of the first strike on the air release of the cuff is the systolic («upper») blood pressure, and at the point of disappearance of sound – diastolic («lower»). To the measured data as accurate as possible, please observe the following rules.
