Sphygmomanometer

=Sphygmomanometer= //Sue P.//

Why used sphygmomanometer? This medical device was used for measuring blood pressure, another name for this would be blood pressure gauge or meter. Since, humans eat three course meals a day, one out of thousands of people would love to know how their blood pressure level is doing. Therefore, blood pressure meter will give people the accurate blood pressure level as it could. Blood pressure is a measurement of the force applied to the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped, and the size and flexibility of the arteries.

=Where is the word //sphygmomanometer originate????//= The word "sphygmomanometer" came from the Greek words "sphygmos" means "pulse" and "manometer" means "pressure meter" altogether both words made a one large words called, sphygmomanometer.

=Did you know.....= Most human beings have blood circulating around their body 24/7?. Of all the blood that we have, they were all come from a single organ, which known as the heart. With every heart beats that your heart does, the majority of the blood carries oxygen and nutrients throughout every single parts of the human body. Hypertension is another name for high blood pressure. It is also known as a "silent killer", because sometimes people do not have any sign or symptoms of hypertension. Therefore, it can be deadly to most of us if we did not watched what we == are eating. That's why people have to get their blood pressure check every two years. Yet, if it is a really severe one, then people must get it checked at least twice a year, depending how worst the condition was.

== =History= Physiologists that studied animal, have already knew about measuring blood pressure. Yet, in 1700s physicians finally figured out how to measure blood pressure in human, as well as detecting blood pressure in our body. Also, physicians have discovered hypertension and chronic high blood pressure, which are highly severe condition that we don't want to found ourselves in. Today sphygmomanometer was introduced in the year 1901 and in 1847 the first human blood pressure was ever recorded. Nevertheless, there are three different types of blood pressure meter, the digital sphygmomanometer, the, as well as the mechanical sphygmomanometer.

=How does it work?= Before measuring the blood pressure, the large cuff have to be placed around the arm. What the cuff to is it help applied pressure for the blood to flow through the arm so the sphygmomanometer could accurately read the blood pressure. As the cuff inflate it stop the artery blood to flow, then when it release the nurse could used their stethoscope to listen to the sound of the blood going back to the artery. For the valve it is a pressure that mainly release mechanism for the cuff. Then the dial was to record the mercury pressure in mmHg. Therefore, the nurse have to decided if the it's a diastolic or systolic pressure. Sphygmomanometer is some what like an Ideal Gas Law, which the Ideal Gas Law do relates to pressure, temperature, and volume.

Basically, it is an instrument for measuring the arterial blood pressure. There are various types, the most common consisting of an inflatable cuff that is placed around the upper arm (usually the left) and air pressure within the cuff is balanced against the pressure of the blood in the brachial artery. The pressure is estimated by means of a mercury or an aneroid manometer. A stethoscope is normally used in conjunction with the instrument to listen to the blood pressure sounds (a stethoscope is not needed with an electronic sphygmomanometer). Normal systolic (high) and diastolic (low) blood pressures in a young adult are about 120/80, respectively and is the standard blood pressure level. The difference between the two pressures is called the pulse pressure. Blood pressure varies with age, gender, altitude, disease, stress, fear, excitement, exercise, etc. A normal range for systolic pressure is usually considered to be 100-140 mmHg and for diastolic pressure below 90 mmHg. Also, if your blood pressure are higher than 120/80 that means your heart have to work extra hard to pump all the blood trough the body, which is not good at all.
