What is an IV Bolus?  How is it different from an IV?
80683
An Iv bolus is usually done when a person has a low blood pressure. It is a large volume of fluid (usually normal saline) That is delivered at a fast rate over an hour. Usually in my hospital it is 500 ml. It can also be a drug injected to an IV like heparin.The fluid bolus differs from a regular Iv drip in the fact that it is delivered with a faster rate.

It depends on the medicine being administered, but usually it means clamping off the IV so that fluid isn't flowing and inserting the needle into the IV access port (use alcohol to clean this port first).  Then administer (push) the medicine into the IV at the rate required for that medicine (some are fast, some are slow, etc...).  Then unclamp the IV fluid and let it flow!

IRV = inspiratory reserve volume\nERV = expiratory reserve volume\nRV  = residual volume\nVC  = vital capacity\nIC  = inspiratory capacity\nEC  = expiratory capacity\n\nDetails on what each means is available at: http://en.wikipedia.org/wiki/Spirometry

There will be a needle, but probably only one, to start an IV. An IV needle hurts less than a shot, because it doesn't go into the muscle, jut the skin and blood vessel.\n\nIf you are this frightened, make sure your docs, nurses and anesthesiologist all know. They can give you something to help or help you understand what's going to happen. A calm patient usually heals better than a terrified one, so they will help.\n\nMost general anesthesia is given--at least the part that you will actually experience--in the IV. They usually tell you to count backwards from ten. Few people get to six before they're asleep. It actually feels VERY nice, like happy, dizzy, and passing out, kinda like some illegal drugs. But it lasts only a few seconds, so don't worry.\n\nThe ONLY job the anesthesiologist has is to keep you asleep, comfortable and alive, and believe me, they concentrate fully on that job. You'll do fine.

Well there are a couple of forces to consider. Gravity determines that no matter what the weight of the object speed should be the same, but we know that doesn't always happen. That's because in this case some a major variable is set. The viscosity of the blood is probably much higher then the normal saline. In determining flow through a pipe the cross sectional diameter, and resistance secondary to viscosity are the main contributing forces. Assuming equal amount of starting solution, and exactly the same lines to flow through, the more viscous liquid will flow slower due to turbulence from decreased laminar flow. Of course you also have to consider if any external forces being put on the iv bags such as; air pressure, pressure from the iv bag being shaped differently, and not to forget that nothing is ever made the same...including iv lines. Anyway there are a lot of different variables contributing to your problem, but scientifically the main contributing factor in your case is probably is viscosity.

Patients admitted into the Intensive Care Unit (ICU) have an intravenous (IV) catheter (small plastic tube) placed in their vein. Very occasionally (4 times out of 100) the insertion of an intravenous catheter may cause an infection in the blood. It has been shown that the removal of the catheter and the insertion of a new one at a new site helps to get rid of this infection. Sometimes, antibiotics are also given. \n\nVancomycin is the antibiotic given intravenously (into the vein) to treat these catheter-related infections. At Vancouver General Hospital, some physicians may not give any vancomycin at all whereas others may treat with intravenous (IV) vancomycin for one to fourteen days.

Try this online IV infusion time online calculator, not sure if it is what you are after but it looks like it is in the right direction\n\nhttp://www.manuelsweb.com/basic_time.htm

Starting IV's is an acquired skill that can take a while to really get the hang of. As a medic I have seen many different approaches to getting the stick on the first try. Allot of problems I see when people can't advance the catheter is because it isn't in the vein all the way. After you get flash in the angio chamber drop your angle and advance the catheter just alittle further. Then try advancing it. This will ensure that the catheter is in all the way. Another trick is to not hit the vein from the top. You can try a slight angle and hit it from the side. This will help with troublesome veins that roll on you. Hope this helps.

Easiest way to remember medical terminology is to learn how to break down the words. In this case... hypertonic (hyper=increased, tonic=osmotic pressure) and hypotonic (hypo=decreased, tonic=osmotic pressure). As you probably already know, osmotic pressure is the pressure that develops when two solutions of differnet concentrateions are seperated by a semimpermeable membrane, kinda like an egg when looking at the yolk versus the white.\n\nDon't laugh or groan, but I'm attaching a site that one of our instructors gave us when I was in school. It actually works and you can see where you're going with osmoality. Trust me, if you walk through the exercise, it'll click better than when anyone was trying to explain it to our class. \n\nGood luck!\n\nhttp://www.the-aps.org/education/outreach/outreach/acts-labs/halversn1.htm

it is very simple \nif ur blood type is o+ than u can receive blood from o+ and o-\nif ur blood type is o- than u can only receive blood from O-

Maybe because it is a faster, more intense high (not that I know from experience) but having talked to someone who was a former IV drug user, he said that other routes (smoking, snorting) take longer to get high and the high is not as good.  Having said that, to anyone who thinks that "hey, cool, she just gave me a great idea", my friend is also living with HIV (contracted through IV drug use) and had to have a line sewn into a vein going into his heart to deliver meds since his veins in his arms, legs etc are too scarred to use.  Seems like one hell of a price to pay for a little fun.

A graduated cylinder is calibrated to contain and dispense....it is an accurate tool for measuring volumes. A beaker is for containing and is not intended to dispense. As long as a few rules are followed an graduated cylinder is accurate to dispense within the limitations set on the cylinder. The rules include following the substance's rules for reading the meniscus. (bottom middle or top) for different substances with different specific densities. \nA beaker is for mixing and containing and has much different tolerances for dispensing.

Its called an air embolus.  When receiving a shot (any shot - vaccine, insulin, etc) you should always "tap out" the bubbles in it.  You never know what can happen.  I'm in school studying to be a physician assistant.  One day in class, our professor told us a story about a resident who walked by a patient receiving some sort of treatment.  He noticed that something was hanging done and plugged it into the patient's IV line.  Unknowingly, this pushed air into the IV line and about 5 minutes later this patient died.  IT doesn't take long at all.  Also, be aware that this isn't the only type of embolism out there - after birth women can experience an amniotic fluid embolus, after fracturing a long bone one can have a fat embolus, and the most common type is a pulmonary embolus which results usually from the lower leg and inactivity (such as a long  trip).\n\nAn excerpt from the article I site:\n Large boluses of air (3-8 mL/kg) can cause acute right ventricular outflow obstruction and result in cardiogenic shock and circulatory arrest. Intermediate amounts of air collect in the pulmonary circulation and produce a pulmonary vascular injury manifested by pre- and postcapillary pulmonary vasoconstriction, pulmonary hypertension, endothelial injury, and permeability pulmonary edema. \n\nVAE is associated with significant morbidity and mortality.

Well, it is easier to drink, and it may have more sugar, therefore the absorbtion of into your bloodstream is actually easier.  or, bc it is yummy, who knows??

I am certified nurse assistant and from my experience I would have gave her an IV to help replenish the fluids. Confusion is often a result from dehydration also. Also I would have given her a blood and or straight cathed her (place a temporary in and right out catheter) to get a little urine since she was dehydrated I am sure she wasnt producing much if any. test just to see how far dehydrated she was so I would know the correct amount of fluids to place in her IV. She should never have been sent home like that. I see medical malpractice honestly. I am sorry for your loss.

Which method of deaeration are you using?  It makes a big difference.  Definitely less than 0.1 mg/L.
