How IV Infusion Works in a Patient IV (Intravenous) infusion means “into the vein”. Intravenous medication administration takes place when you insert a needle into a vein and medication is administered via that needle. IV infusions are used to administer drugs, blood, essential nutrients or fluid into a patient’s blood. It begins with the insertion of a needle into the patient’s vein through the skin. This hypodermic needle is attached to a tube that channels liquid from a bag that it is connected to. The liquid which contains one or more kinds of medication, is released into the tube gradually through a manual valve control system on the drip or through electronic pumping mechanisms. This liquid is channeled directly into the blood stream through the vein which sends the blood into the heart, where it is pumped to every part of the body. The medication reaches the areas affected and begins to carry out its corrective function in the body. Sometimes the IV is given to hydrate a severely dehydrated body, in which case all the cells are impacted by the infusion. IV administration is faster than any other method of administration because it flows directly into the blood stream, so it is used when rapid action of the drug is necessary. The needle is usually inserted into in a vein close to the elbow, the wrist, or placed on the back of the hand. IV infusion works effectively because gravity pushes the fluid down through the IV tubing into the patient's vein. The higher the bag is hung, the greater the gravitational pressure on the IV fluid to flow downward through the tubing. To get enough pressure for gravity to force the fluid into the vein at a constant rate, the IV bag needs to be hung high. So, all IV bags must be hung above the ... ... middle of paper ... ...kly administer medication to a patient that is in urgent need of it. How this medication ends up in the blood stream to effect a change in a patient’s body is determined by the adherence to the standard steps of inserting an IV. This includes finding a peripheral or central vein; inserting a hypodermic needle; and regulating the amount of fluid that goes into the blood stream from the bag containing the liquid medication or nutrients. The IV infusion must be monitored intermittently to ensure that the needle does not become dislodged from the vein and pours its contents into surrounding tissue. This could lead to irritation, pain and other symptoms. Also the rate of infusion must be appropriate for the medication being given because too much infusion can cause other problems for the patient.

He quickly hooks up an IV fills it with diet water and waits. Ten tense minutes pass before the beeping of the machines resume their natural rhythm and the patient is stabilized. Suddenly, the patient begins to radiate a pale, golden light.
The nurse, a traveling nurse, was working on a unit and received orders for infusion of normal saline in a 7 month old. He saw a small bag of what appeared to be saline on the desk in the nurse’s station, with the manufacturer’s pre-printed labeling indicating that it was filled with normal saline. One key aspect, as described by the traveling nurse, was that he had encountered in other health systems that pediatric infusions were specified in small bags. Based upon these two perceptions, the nurse administered the infusion – despite the pharmacy applied label being on the other side of the bag. Needless to say, the child died shortly after receiving the infusion, despite resuscitation attempts. The infusion was actually prepared for his adult patient

It is a closed system where the patient’s blood goes straight from the vein to the inside of the tube through the rubber stopper present at the entrance of the tube without the blood being open to the air. You can collect many tubes by using just a single venepuncture. There is three components required for the evacuated system: double pointed needle, plastic holder or adapter and evacuated sample tube. All constituents of the system ought to be from the same manufacturer to avoid difficulties with the correct needle fit and smooth placement and removal of tubes. The tubes used with the evacuated tube system for blood collection are known as evacuated tubes. With the evacuated tube, blood can be taken straight from the vein into the tube without exposing it to air (closed system). This reduces accidental contact with blood. These tubes have a preset vacuum based on the volume of the tube and the type and amount of additive used in the tube. When the rubber stopper of the tube is penetrated with the back-end of the needle in the needle/tube holder, blood is drawn into the tube from the vein by the vacuum. The vacuum in the evacuated tube permits the accurate amount of blood to go into it. Regardless of whether the anticoagulant in the anticoagulant tubes is a liquid, powder or spray on the inside of the tube, they must be allowed to fill to the finishing point. By not completely filling the
IV sedation is reserved for our most complicated procedures and patients with very high levels of fear and anxiety. IV sedation creates a sleep-like state that allows you to wake up from a procedure with no memory of the sights, smells, sounds, or sensations that occurred during the treatment. This form of sedation is administered through an intravenous line and only by a licensed
Intravenous therapy (IV therapy) is a method used to help the patient get better. Intravenous lines are put in for things as simple as delivering fluids when the patient is dehydrated to administering emergency lifesaving pharmaceuticals. As a patient or health care provider negative outcomes, such as having unneeded complications and jeopardizing patient comfort from an intravenous line is the last thing needed.
Several skills are beneficial to the nurse and paramedic, but perhaps one of the most important skills is the ability to place an intravenous catheter into a vein. This procedure is most commonly referred to as “starting an IV”. In today’s medical community, intravenous cannulation is necessary for the administration of many antibiotics and other therapeutic drugs. Listed below are the procedures and guidelines for starting a successful IV. Following these instructions will provide a positive experience for the patient and clinician.
The patient was identified and the procedure was explained preliminary to administering the injection, to ensure the patient fully understood the procedure and to gain consent from them. The possible side effects of the medication were outlined aswell. ...

When administering medications it is critical to pay great attention to the task at hand. This task becomes more important when administering medications to the elderly because of the different physiological and psychological changes that occur in the body. Equally important are, the lab values related to the medications being administered, differences in administering medications to the elderly, and the use of the six rights and three checks.
Before your first treatment, an access to your bloodstream must be made. The access provides a way for blood to be carried from your body to the dialysis machine and then back into your body. The access can be internal (inside the body -- usually under your skin) or external (outside the body).
I also plan on taking a course after graduating from the nursing program specific to IV therapy because I feel this is a skill that takes practice and not having the hands-on experience through the nursing program at Niagara College is unfortunate. The IV therapy course is offered at Niagara College for a six-week period. I feel by taking this course I will become more comfortable with IV’s and will meet the expectations of the CNO when providing care to patients as a future nurse. I will also use the CNO standards of medication when administering an IV solution because it is a medication and the 10 rights need to be applied (CNO,

The venous system carries the blood back to the heart. The blood flows from the capillaries, to venues (very small veins), to veins. The two largest veins in the body are the superior and inferior vena cavas. The superior vena cava carries the blood from the upper part of the body to the heart. The inferior vena cava carries the blood from the lower body to the heart. . Many people believe that the blood in the veins is blue but in actuality it is not. Venous blood is really dark red or maroon in color. Veins do have a bluish appearance and this may be why people think venous blood is blue. Both the superior and inferior vena cava ends in the right atrium. The superior vena cava enters from the top and the inferior vena cava enters from the bottom.
The circulatory system consists of many different components and structures for specific functions. For example controlling the blood flow to go one direction, for one blood vessel to hold more blood than another, and even a system that decides when the heart beats. As the circulatory system was studied and observed, questions were raised of how the blood flow goes only one way. In the heart and between each chamber, there are four valves that control the amount of blood flow in the heart. As the oxygen poor blood flows into the right atrium through the respective vena cava’s, it is stopped until the heart contracts and the tricuspid valve opens, letting the blood flow into
