Blood Pressure

Normal blood pressure is important for blood flow suits the needs of the human body. Every heartbeat pushes blood to the different parts of the body and blood pressure ranges from high when it is near the heart and lower when it moves away from him. The force of the blood on the walls of the arteries is known as blood or blood pressure. As a general rule, blood pressure is highest when the heart pumps blood. And just to measure pressure or blood pressure there is a very useful tool, the tensiometer.

What is a Tensiometer, their Types and Parts

The blood pressure, also known as sphygmomanometer, is a medical instrument that establishes the indirect measurement of blood pressure. There are several types: mercury, digital and aneroid. This instrument consists of a sleeve with an inflatable bladder, a graduated gauge, a tube connecting the gauge to a bulb syringe and a valve that controls the air outlet.

Taking blood pressure is important to know how a person is in relation to its circulatory function.

How to Measure Voltage Correctly

The person should be sitting with his back against the back of a chair and the arremangado arm. After the cuff around the bare arm wraps (the lower edge should be at two centimeters above the elbow). the diaphragm of the stethoscope is then placed on the lower edge, exactly between the arm and the cuff. Then begins to inflate it tensiometer using pear, so that the meter reaches 180 millimeters mercury. In the next step the valve is slightly opened to allow pressure slowly go down. And as the low pressure stethoscope is used to record the B P reading (a value corresponding to the systolic and the other refers to the diastolic pressure). A value of blood pressure within the normal range would be 120 over 80 millimeters of mercury and if higher or lower levels are recorded should consult a doctor.

A Painful Instrument in its Infancy

Current sphygmomanometers (both manual and digital) do not cause any pain or discomfort. However, the first that appeared in the eighteenth century itself were really uncomfortable, since glass tubes connected to an artery were used. Over time measuring probes were introduced in major arteries. These invasive methods disappeared in the late nineteenth century when tensiometers were introduced such as we now know them.
