what is the difference in a combi tube and an et tube?
407757
Combi tube has an esophageal port and a tracheal port, it has 2 balloons on the tube.  It is used mostly in an emergency situation and does not require visualization of the larynx. It can be placed in either the trachea or the esophagus. Since you place it in blindly, it usually ends up in the esophagus.  An ET tube has one port and one balloon, and visualization of the larynx is required.

Check out this page http://osuextra.okstate.edu/pdfs/F-3158web.pdf It's got a ton of info about ET on it.  Good luck on your project!

In the lab we used to enlarge the hole on micropipette tips when pipetting things like glycerol. Just cut off a little bit of the tip with a razor blade. With samples over 1 mL we were just patient because the plastic disposable pipettes tend to shatter if you try to trim them a little.

The first three answers are correct, but confusing. Let me see if I can't simplify this for you. \n\nThe pipe expands in all directions. Assume that the pipe is made of a uniform material, like copper, so we can say that it expands uniformly in all directions.\n\nYou must understand that the metal expands uniformly per unit of measurement. Think of a strip of metal, first. (our piece of tubing cut down the side and unrolled flat.) This means not only that the length, width and thickness expand-- it also means that it will expand so much PER UNIT.\n\nSuppose the copper will expand 1 mm per cm. (We'll use metric, just to keep it simple, because everything will be in tens.) \n\nIf the thickness of the copper strip is 1 cm, \nit will expand to 1.1 cm, or 1 cm plus (1 x 1mm.)\n\nIf the width of the strip is 20 cm, \nit will expand to 22 cm, or 20 cm plus (20 x 1 mm.)\n\nIf the length of the strip is 200 cm, \nit will expand to 220 cm, or 200 cm plus (200 x 1 mm.)\n\nNow, suppose we roll the strip back into a tube again. \n\nThe inner circumference of the tube started out as 20 cm, and the diameter was 20/ pi (which is something less than six cm.)\n\nThe new inner circumference is 22 cm, and the new diameter is 22/pi, which is greater than seven cm. \n\nSo, the metal expands proportionately in all dimensions, and the with of the strip (the circumference of the tube, and thus the diameter) expands MUCH MORE than the thickness of the strip, (which is the same as the tube wall). \n\nIs physics cool, or what?\n\n10 NOV 06, 0419 hrs, GMT.

I can't say for certain, but I assume the length of the gaps does not increase.  The length of the tubes increase so that the time it takes to traverse the tube stays the same.  I think the only constraint on the gaps is how close the tubes can be to each other.  You'd want it to be as small as possible to get as much accelleration as possible.

The process is called intubation, and the tube is called an endotracheal tube, or ET tube for short.\n\nIt does depend on the type of operation you have, and what type of anestetic is used. Normally, if you are under "general  anestetic" you are intubated.\n\nIntubation involves the insertion of the ET tube between the vocal chords, and into the trachea. The ET tube has a hole at each end, and the end of the tube that resides in the trachea has an inflatable balloon that helps keep the tube in the proper place. \n\nOnce completed, intubation creates a "patent airway" which means that the air & oxygen is getting directly to the lungs.

a t-tube by the way is the most cruel thing u can ever do to a patient its like breathing through a straw. But anyways, it is just a way to take a patient off of a ventilator to see if they are ready to be extubated without having to reintubate them. there are ways to do it with vent settings but some docs are just plain dumb and cruel and prefer that method. the po2 for that percent of o2 s low...

A test tube and a florence flask both are containers for holding chemical solutions. \nA watch glass is used to evaporate liquid or to cover a beaker.\nGlass tubing is used for carrying gases between pieces of apparatus during an experiment.\nA buret is used for dispensing known amounts of a liquid reagent in experiments where measurements need to be precise.\nAnd a thermometer is used for measuring temperature.

Thanks for the question, now i know as well.\n\nhttp://cobweb.ecn.purdue.edu/~heister/liqjet.html\n\nhttp://www.nature.com/nature/links/030109/030109-8.html

graduated cylinder... although you get a higher degree of accuracy with volumetric pipettes. :-)

The tubes need an initial surge of electricity to overcome the higher resistance that exists before the current is flowing.  Usually this is done by charging a capacitor to a high voltage.  I believe the click is the initial electric discharge.

morse tapers come in various sizes from 0 up to a 8 which is huge,is it a hand held or a freestanding one? go to engineer or shop they will tell you just by looking,as i would if i could see it. but alas i cannot

The symbol is called an ampersand.  It's use goes back to Latin.  It was a combination of the letters E and T from the Latin word et meaning and.  You might do a search on the name ampersand for more details.
