What is blood pressure used to evaluate?

Your systole and diastole (or systolic and diastolic pressure). Systolic pressure is the pressure your blood exerts on blood vessels when your heart pumps out blood while diastolic pressure is the pressure your blood exerts on blood vessels when your heart is at rest(in between pumps). Blood pressure is stated as systolic pressure/diastolic pressure. The normal BP is 120/80 mmHg.


How can an ACE help mediate her blood pressure?

An ACE inhibitor (or angiotensin-converting-enzyme inhibitor) is a pharmaceutical drug used primarily for the treatment of elevated blood pressure. This group of drugs causes dilation of blood vessels, which results in lower blood pressure. ACE inhibitors decrease the tension of blood vessels and blood volume, thus lowering blood pressure.


What is Gelafundin?

Gelafundin is a substance that is used to increase intravascular volume (the volume inside blood vessels). This may be used for example in case of a low blood pressure (because an increase in the intravascular vol causes an increase in blood pressure) until blood is available.


What instrument is used to measure air pressure?

There are several options depending on the type of air pressure being measured:In the 1800's ships used a weather glass - a simple barometer - to measure changes in air pressure.To measure atmospheric (ambient air) pressure, a barometer is used. (It may be either an aneroid or a Mercury type of barometer.)For tires, it's a tire pressure gauge.In industrial processes and boilers the gauge is frequently called a manometer.For pressure vessels it is a Bourdon gauge.

Kings put crowns on their (not "there") heads.


What do the two number in the blood pressure mean?

Blood pressure is pressure exerted by blood on the walls of blood vessels. The two numbers represent the systolic and diastolic pressure. Systolic pressure is the pressure exerted during ventricular contraction(also called systole) and diastolic pressure is the pressure exerted during ventricular relaxation(also called diastole). The units of blood pressure are millimeters of Mercury (mmHg) because it represents how far up a tube the pressure can push a column of mercury, which was how pressure used to be measured.


What is meaning rating of pressure vessel?

A pressure vessel is built to withstand more pressure than it will ever be subjected to in practice. Such a vessel, after its construction, will be tested to see that it can safely bear far more pressure than it needs to bear while doing its normal job. I used to play hockey with a chap who tested such vessels. We called him the "Boiler Buster".


What years did Harley Davidson iron heads?

Of the OHV models, the Knucklehead (36 -47) used cast iron heads, and the Sportster used iron heads from 57-84.

Why are cylinders are used transport LPG gas?

LPG gas is transported under pressure, and cylinders are just the easiest way to build pressure vessels. If you'd try to put it on square containers, the sides would bulge, and spherical tanks are awkard to make and to transport.


What is the minimum design pressure in ASME sec viii?

ASME Section XIII does not define a minimum design pressure. Many vessels are designed for full vacuum according to the requirements of the code. A storage tank (API 650 or API 620) can be used in place of a pressure vessel provided that the gage pressure is not more than 15 pounds per square inch.
