Q:Aortic valve replacement surgery?
This is a routine, well established procedure. The incidence of major complications are less than 4%. There are two kinds of artificial Heart Valves. One is mechanical, and the other is tissue valve. The mechanical valve requires the person to be on life long anti-coagulation therapy. This also requires periodic check on the persons pro thrombin time. Based on this, the anti-coaglation dose will be adjusted. The problem with anti-coagulation is that it may lead to bleeding complications. The tissue valve is made from the tissues of a bovine or porcine heart. The tissue is denatured to ensure that the valve is not rejected as a foreign tissue. (This is not a problem with mechanical valves.) Being made of tissue, these valves do not allow clots to form, which means that anti-coagulation after a short initial period is not required. This is a major advantage, especially for women, who may have some earlier bleeding problems. Then why are mechanical valves used at all? Being made from non-living denatured tissue, tissue valves cannot repair themselves. They also tend to get calcified in younger people with more calcium activity. They also have a shorter life than mechanical valves. Surgeons tend to favour mechanical valves for younger people (whose life expectancy is higher), and the tissue valve for the older, as such people may already have some bleeding problems, the valve's durability is not critical and the patient has lower calcium activity. These are general considerations. Only a surgeon armed with the full test results, and a knowledge of the patient history, who can advise the patient on what is the best option in each case. To reiterate, AVR (Aortic Valve Replacement, not my initials) is a routine procedure and recovery tends to be uneventful. Wish you all the best, and as uneventful a recovery as possible.
Q:2004 Nissan Maxima VIAS SOLENOID VALVE Repair Manual?
This is NOT a very serious problem. You have an ADJUSTABLE intake runner on this engine. THere is a vacuum operated CONTROL valve very visible with the hood open. It SHIFTS a doorway within the manifold to alter the path of incoming air. THere is a SOLENOID that controls this FLAP IT ALSO is easy to find in plain view if you follow the VACUUM to the valve. Many times ths VACUUM hose itself has collapsed, a VERY cheap repair. WOrst case scenario is to repalce either the SOLENOID or the actual VALVE. It has a rubber diaphragm within it. JUNK yards may have good used ones. You can remove the VACUUM to this valve, and try sucking on it to see if the valve MOVES the flap[ hidden inside the INTAKE MANIFOLD. EZ test, EZ fix. GOOD LUCK!!
Q:Silent sump pump shut-off valves?
Silent Sump Pump
Q:Turning on the main water valve?
you should get water immediately unless water is blocked
Q:Alternate valve oil for trumpet?
Honestly, vaseline will screw up your valves over long uses as the viscosity of the material will make your valves stick harder. Baby oil has minerals in it that will eventually build up on the valves and start corroding it. The best lubricant you can use is saliva because it will not create build up. It is cheap and effective but not recommendable. I remember my valves were stuck right before a show, but I spit on them and they worked fine. Its a short term solution, but go out and buy some valve oil.
Q:Tell me all you know about Blow-off valves?
It is often used as a safety devise in many industrial fields, first introduced on the early steam engines of the 19th century to prevent the boilers from blowing up due to excessive steam pressure. They still did often blow up as the early valves were quite primitive and often stuck closed,
Q:what is an air control valve, used for air line tubing?
air control valves are use for any sort of tubing or air pumps/air stones. air control valves are used to control the amount of oxygen/carbon dioxide allowed into your aquarium from the source. usually air pumps come with a air control valve but if not i suggest using one. also when using any sort of air line tubing connecting from the aquarium and out of the aquarium use a check valve! check valves are so important because it prevent water back flow out of your aquarium and into your cabinet,air pump, and of course you floor/carpet!
Q:Will a valve adjustment fix the leak of a bad valve stem seals?
Don't okorder.com
Q:Water Heater Relief Valve keeps opening.?
after a few years they just go bad, replace it.
Q:i can't pump my presta valve...?
Be careful pumping prestas. If you're not using a pump with a hose, much back and forth movement of the valve stem will cause it to split. In fact, that may have already happened and that's why no air is going in the tube.
