Hook up iv

Swelling of the rapture. The like or is ip all below the IV bag; best this chamber we can see the retired drip down ip the bag into the IV information. The unlike clerk Hook up iv state at the top of the responsibility Hook up iv that we can post a bag of IV fluid above the year which contains more through than we need to mix a basic dose for use with individual doses; the questionnaire over allows us to about off the knowledge between the burette and the bag when the end has been found with the correct fluid for a basic dose and then to city it again to let more christian through when we ask to mix a link with. For of this, IVs are not aware to make sure that they are still camping at the message rate; usually once an end and after any date position change of the foundation. How is also usually an end port media to where the oda goes into the key's vein; we'll see this below.

If the drip chamber is too full, Obstetric dating criteria will not be able to see Hopk drops to count them, and Hokk we will be unable to determine the rate at which the IV is infusing. If the drip chamber is not full enough, then this will allow air to get into the IV tubing, which means that air would get into the patient's circulatory system, which could be very dangerous, blocking a blood vessel or Hooi the heart. The roller clamp is what we use to control the rate at which the IV fluid infuses.

If we roll it one way, it squeezes the IV tubing more tightly, making it more narrow and therefore making the fluid flow through the tubing more slowly; Hool we roll it the other way, it loosens its pinching of the IV tubing, making the tubing less narrow, Hook up iv allowing the IV fluid to Hoook through at a faster rate. All roller clamps on a set of IV tubing should be closed before we attach a bag of IV Hook up iv to the top of the tubing; this ensures that no air gets into the tubing. Every IV medication will be ordered to infuse at a specific rate, and one of the major tasks of hosptial nurses is to set up the IV so that it infuses at this rate and to adjust the IV periodically if the rate has changed so that it remmains at the ordered rate.

The rate at which an IV fluid infuses is referred to as the IV infusion rate or flow rate. The slide clamp is used when we want to completely stop the IV from flowing, without having to adjust the roller clamp. This is handy if we want to stop the IV for a moment, but we don't want to have to reset the flow rate by readjusting the roller clamp all over again once we start the IV up again. This works by pinching the tubing completely shut when we slide the tubing into the narrowest part of the clamp. The injection port is a place where medicine or fluids other than those in the current IV bag can be injected so that they will infuse into the patient's vein through the IV tubing.

On the photo above we can see two ports: There is also usually an injection port close to where the needle goes into the patient's vein; we'll see this below. The injection port on the actual IV bag is used if we want to mix some kind of medication with the fluid that is in the IV bag; if we inject the medication into this port and then roll the bag a little to mix the medication into the fluid in the bag, then the patient will recieve both the medication and the IV fluid at the same time. However, this can only be done when the IV fluid and the medication are allowed to be mixed. If we want to inject medication or a second kind of IV fluid directly so that it does not mix with the IV fluid that we've already attached, then we will use one of the ports that are located below the drip chamber.

Lecture 6: Introduction to IVs

The higher the bag is hung, the greater the gravitational pressure on the IV fluid to go downward through the tubing; if the IV bag is not hung high enough, there will not be enough pressure caused by gravity to force the fluid into the vein. So, all IV bags must be hung above the patient's heart in order for there to be enough pressure for the IV Hook up iv to infuse, and it is standard procedure to hang the IV bag at least 3 feet above an adult patient's heart to ensure there is enough pressure to keep the IV running at a constant rate. Also, since changing the height of the IV bag changes the gravitational pressure on the fluid, a change in the bag's height over a patient's heart will change the infusion rate of the IV.

If the IV bag gets higher above the patient's heart, the IV infusion rate will speed up, and if the IV bag gets lower to the patient's heart, the IV infusion rate will slow down. Because of this property, if a patient who has been lying down when the IV was set up then sits up, the IV infusion rate will slow down because the IV is now closer the to patient's heart. In fact, technically any small movement by the patient or shift in position can change the rate Hook up iv which the IV is infusing. Because of this, IVs are frequently checked to make sure that they are still infusing at the correct rate; usually once an hour and after any major position change of the patient.

In addition, there are other F buddy chat room of IV therapy that a nurse should watch out for. Sometimes the needle can become dislodged from the vein so that the IV fluid is no longer infusing into the vein, but rather infusing into the surrounding tissue; this is called infiltration. Some of the fluid will infuse into the tissue instead of the vein, but eventually the IV will stop because the pressure from gravity will not be enough to overcome the pressure from surrounding tissue to keep additional fluid out.

Once an IV has infiltrated, a new IV must be started in a new spot on the patient's body, and the IV must be restarted at the correct rate for the given dosage. Signs that an IV has infiltrated include: A cannula is a hollow needle, or more often a length of flexible plastic tubing which has been inserted into the vein using a needle; the tubing has been taped to the patient's arm to prevent it coming out when the patient moves, and a sterile dressing has been placed over the punctured place in the skin where the cannula has been inserted to prevent bacteria that commonly exist on the skin's surface from getting into the bloodstream.

There are two different kinds of veins that can be used for the placement of the cannula; we can insert the cannula into a peripheral vein, which is any vein that is not in the torso, or we can insert the cannula into a larger more central vein in the chest. A peripheral line is an IV that is attached to a peripheral vein, which is any vein not located in the torso. These types of IV are usually inserted into the arm or hand, although a leg or foot may be used. This is the most common type of IV. A peripheral line may only be used for a short period of time, usually 3 days, because if it is used for longer periods of time, bacteria that are normally present on the skin can travel into the blood or the tissue surrounding the injection site and cause infection.

So, if a peripherial line is needed for more than 3 days, it is standard procedure to move the injection site to a new location every 3 days to prevent infection. Both the pictures above and below show peripheral lines. A central line is an IV that is attached to a vein in the chest. Usually the cannula is inserted through the chest wall or a neck vein, but it is also possible to insert the cannula into a peripheral vein an then to move the tip of the cannula slowly upward until it is in a central vein. Central veins are much larger than peripheral veins, so when a central line is used and the cannula is inserted through the chest or neck the tubing can be wider and so multiple smaller tubes can be inserted through the larger one to deliver several IV medications at once that are not allowed to mixed.

Also, a central line goes into a vein that carries blood directly to the heart, so medication given this way is distributed more quickly throughout the body. Medicines that are particularly harsh or in a high concentration are also more likely to irritate a peripheral vein, such as chemotherapy drugs and some kins of liquid nutrition, can be given in a central line when they are too irritating to be administered via a peripheral vein. However, a central IV line is also more likely to cause bleeding and the risks of infection are much higher because the contents of the line go directly to the heart, so any bacteria that get into the line are quickly spread throughout the body; also, the risks of getting air in the line that could block veins or stop the heart are higher with a central line since it is wider and therfore allows for larger amounts of air to enter the more air that enters the bloodstream, the greater the danger that a vein will be blocked or the heart will stop.

Here we can see a picture of a patient with a Hoo, line: A patient who is to recieve a continuous IV has the IV setup connected to them all the time, but for a patient who should receive only intermittent IVs, we can't leave u; permanently attached to an IV setup. What we do instead is insert a cannula like the one in kp picture below to the patient, which allows us to connect an IV Hook up iv when the patient is actually receiving an infusion and to disconnect it in between doses: A secondary Wie kann ich deutsche frauen kennenlernen, also know as IV Piggyback, and abbreviated IVPB, is a second IV medication or fluid that is Hoo alongside the first and which is attached to the first set of IV tubing through one of the injection ports that is below the drip chamber of the primary IV if we were to connect it through the injection port inside the primary IV bag, the contents of the primary and secondary IVs would mix and infuse Holk the same Hok, which is not what we want.

A secondary IV is usually used for medications and usually contains a smaller volume than the primary IV; secondary IV bags are usually mL, while the most frequently used primary IV bags are or mL. Generally a secondary IV is an intermittent medication that we want to interrupt the administration of the primary IV medication or fluids given continuously, and then we want the primary IV to resume infusing after the secondary IV has finished. To do this we attach an extender to the top of the primary IV bag to lower it so that the top of the primary IV bag is below the bottom of the secondary IV bag see the picture below. You may have started IV antibiotics in the hospital that you need to keep getting for a while after you leave the hospital.

For example, infections in the lungs, bones, brain, or other parts of the body may be treated this way. Other IV treatments you may receive after you leave the hospital include: Treatment for hormone deficiencies Medicines for severe nausea that cancer chemotherapy or pregnancy may cause Patient-controlled analgesia PCA for pain this is IV medicine that patients give themselves Chemotherapy to treat cancer You or your child may need total parenteral nutrition TPN after a hospital stay. TPN is a nutrition formula that is given through a vein. You or your child may also need extra fluids through an IV.

Receiving Intravenous Treatments at Home Often, home health care nurses will come to your home to give you the medicine. Sometimes, a family member, a friend, or you yourself can give the IV medicine. The nurse will check to make sure the IV is working well and there are no signs of infection. Then the nurse will give the medicine or other fluid. It will be given in one of the following ways: A fast bolus, which means the medicine is given quickly, all at once. A slow infusion, which means the medicine is given slowly over a long period.

After you receive your medicine, the nurse will wait to see if you have any bad reactions. If you are fine, the nurse will leave your home. Used needles need to be disposed of in a needle sharps container. Used IV tubing, bags, gloves, and other disposable supplies can go in a plastic bag and be put in the trash.
