what is infusion pump

Infusion pumps large or small volumes of liquids at high flow rates are able to be delivered to the patient, and are used to deliver nutrients or drugs. Such as insulin or other hormones, antibiotics, chemotherapy drugs, and pain relievers etc. are given through this device.

What is an infusion pump

Medications need to go through proper rate and volume so we use infusion pump.

Infusion Pump is a medical device that delivers fluids such as nutrients & medications, into patient’s body in controlled amount.

Infusion is one way to treat or manage neurological conditions/disorder of nervous system. An infusion pumps draws fluid from a standard bag of intravenous fluid & controls the rate of flow.

It provides continuous & accurate therapy. These devices often have enough power to pump fluids, fluid is pumped through tiny catherters into patient’s blood vessels. Autotransfusion units Function and Working Principle

What is an infusion pump

There are types of infusion from technician/nurse that sets them up: –
1. Continuous Infusion: – This has small pulses of infusion between 500 nanolitres & 10millilitres, depending on pump’s design.

2. Intermittent Infusion: – This has high infusion, alternating with low infusion rate to keep cannula open.

3. Patient-Controlled Infusion: – This avoids intoxication & rate is controlled by pressure pad/button that can be activated by patient.

4. Total Parental Nutrition: -This has an infusion curve similar to normal mealtimes. As the Infusion pumps have many benefits some of the disadvantages.

5. Software defects
6. User interface issues
7. Mechanical/electrical failure

what is the Infusion pump advantage and disadvantage


The volume of syringe used limits the fluid dispensing volume.administering drugs intravenously
Excessive resistance may lead to the build-up of pressure and eventual failure of the syringe pump.This injects a needle directly into the patient’s arm.
The flow rate during the transient period cannot be known without flow sensors.This allows for more efficient treatment of chronic diseases.
 It delivers medication, antibiotics and/or hydration directly into the bloodstream.

Continuous Infusion

Its continuous infusion may provide the advantage of maintaining therapeutic levels of the diuretic over a more extended period than bolus administration.

Lipophilic opioids are usually administered to the patient as continuous epidural infusions because their rapid onset and short duration facilitate analgesic titration. Epidural fentanyl mixed with a dilute solution of bupivacaine may produce better analgesic results.

Intermittent Infusion

This intermittent infusion is the best device that is maintained at a moderately slow infusion rate as it minimizes the risk of fluid overload and electrolyte imbalance.

What is an infusion pump

Patient-Controlled Infusion

A computerized pump attached to the IV allows the patient to release pain medication by pressing an automatic handheld button. It is used to reduce pain after surgery. Or it can be used for painful conditions such as pancreatitis or sickle cell disease. It also works well for people who cannot take medicines by mouth.

Total Parental Nutrition

Total parenteral nutrition (TPN), also known as parenteral nutrition (PN), is a form of nutritional support given entirely through the bloodstream with an IV pump. It manages the proteins, carbohydrates, fats, vitamins and minerals in the patient’s body. The main three macronutrients are
a. lipids emulsions
b. proteins
c. dextrose

There are two basic classes of syring infusion pumps. A large volume pump may pump fluid replacements such as saline solutions, medications such as antibiotics or nutrient solutions that are sufficient to feed the patient. Second, small-volume pumps infuse hormones, such as insulin, or other drugs, such as opiates.
