how is hydraulic and pneumatic pressure important to a surgeon's job?

Generally someone is under anesthesia.  The gas is under pressure before it goes to the patient.  Pneumatic pressure would be important in this.

They throw you into the fire and have you do things little by little.  You watch a surgeon do it and you are expected to do it the next time.  You also read about techniques in books, but the way a surgeon becomes a surgeon is by experiece in the operating room.

Depends on the specific surgery being performed and whether they are going in by scope or opening you completely up. Some physicians will do a rhynoplasty along with another surgery, but it is physician dependent and even then decided on a case by case basis. When you go in for your consultation ask your physician if s/he is willing and if you are a candidate.

This is not actually so.  To quote from another source:\n\n"In the past, most attention was paid to diastolic pressure; but nowadays it is recognised that both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are also risk factors."\n\nOr, to put it a more obvious way, if only one number was really important, why would anyone bother writing down two?  The systolic number tells you about how hard the heart works at maximum, and the diastolic can tell you about the minimum flow and the quality of your veins.  Those are both rather obviously good things to know!

Aspirin thins the blood. This means that your blood flows easier, and takes longer to clot.\n\nThis is dangerous during surgery as you will bleed alot, and may loose alot of blood because the cuts dont stop bleeding for a long time. \n\nThere is also a risk of interactoin with other chemicals given in the anasthetic, and pain medication given afterwards.\n\nINFORM THE DOCTOR if you have taken any within 48 hours of the procedure, as the complications may be life-thretening, even for a small procedure!

I don't have statistics for you, but this is a known complication.\n\nSpeaking very, very roughly, I'd guess that in the facility where I work, it occurs to fewer than one person out of a hundred.  I realize that's no consolation when it happens to you.\n\nIn my experience, it usually doesn't require surgical repair.  The monitoring you describe sounds more typical.\n\nFor what little it's worth, I'm sorry this happened to you.

The answer is Pressure\n\n10 pts plz! im only level 1!

Actually in most cases it would be the responsibility of the anaesthesiologist to inform the patient.  Irregardless of just who's responsibility it is, the patient must be informed of all potential risks in any medical procedure, further it must be insured that the patient fully understands these risks.  This is informed consent, all information must be on paper for the patient to sign signifying that she does understand and accept the risks.

you could but be careful.\nit would be better to see a professional and let them know your condition before they start and they should know a safe pressure to use.

Boyles Law PV/T I think. Anyway it has to do with the relationship of Pressure to Volume. If one increases the other decreases. Its useful in industry in making liquid Nitrogen and has endless applications in dealing with gasses in Chemisrty and Physics.

its basically how u see the question.\nin fluid dynamics, eq of continuity specifies that a*v = constant so with inc in area, velocity decreases,hence pressure increses\n\nwhile in solids, the case is not the same , pressure = force/area hence assuming force constant with inc in area, pressure must dec

A hydrostatic test is the normal way in which a gas pressure vessel such as a gas cylinder or a boiler is checked for leaks or flaws. Testing is very important because such containers can explode if they fail when containing compressed gas. Hydrostatic testing is also a way in which leaks can be found in lower pressure vessels such as pipelines and plumbing.\n\nThe vessel is filled with a nearly incompressible liquid - usually water or oil - and examined for leaks or permanent changes in shape. The test pressure is always considerably more than the operating pressure to give a margin for safety, typically 150% of the operating pressure. Water is commonly used because it is almost incompressible, so will only expand by a very small amount should the vessel split.

All substances, gases, solids, and liquids, including water, are compressible. Some \nsubstances just require more pressure per change in volume to compress than others. The \nnumerical value of the compressibility depends both on the temperature and on the pressure \ntoo. That is how hard you have to squeeze at one pressure to obtain a certain fractional \ndecrease in the volume is different than at some other pressure. The same for two different \ntemperatures. Under most "normal" lab conditions however solids and liquids are usually \nconsidered to be incompressible.\n\nTechnically speaking, water can be compressed, but very little even at high pressures.  For \npractical design purposes, water is considered an incompressible fluid, that is, its density \ndoes not change with pressure.  The reason anything is compressible is due to how close the \natoms are packed together.  If you think about air, it is highly compressible because there \nis considerable spacing between the atoms, so it is relatively easy to force the atoms closer \ntogether.  When you have a liquid, the atoms are much closer together and considerable \npressure is required to make them any closer.  Solids will compress some as well, but it \ntakes significant pressure.  Temperature also plays a factor in density (and thus \ncompressibility), just ask your chemistry teacher about the ideal gas law.\nI am not sure what your book was using a "water compression system", but hydraulic systems \nare used almost everywhere to transmit power across a system.  What a hydraulic system does \nis put a liquid (usual an oil of some type) under pressure, route that pressurized liquid \nthrough pipes or hoses, and releases the pressure at a place where work needs to be done, \nusually through a motor or cylinder that transfers the pressure into work.  You might want \nto research on hydraulic systems (hydraulic lifts, hydraulic elevators, etc.) to get a better \nunderstanding on how energy can be transferred around in a hydraulic system.

Pascal's principle : Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container.  \nAn example: hydraulic lift.

First of all my heart goes out to you and your granddaughter.  I was diagnosed in 1999 with ACM1 have not had surgery but deal daily with the pressure and other symptoms.  I don't know what to say about the pressure after a decompression surgery. I can tell you when the pressure is built up it is very painful and one wants to do whatever they can to be rid of it.  Making lifestyle changes and having appropriate pain medicine and a knowledgable Neurologist/Neurosurgeon goes a long way.
