A catheter embolism may occur when a small part of the cannula breaks off and flows into the vascular system. When removing a peripheral IV cannula, the tip should be inspected to ensure it's intact. [5] Because of the risk of insertion-site infection the CDC advises in their guideline that the catheter needs to be replaced every 96 hours. [6]
The estimated blood volume in adult animals is 55 to 70 ml/kg body weight. Care should be taken for older and obese animals. If blood collection volume exceeds more than 10% of total blood volume, fluid replacement may be required. Lactated Ringer's solution (LRS) is recommended as the best fluid replacement by National Institutes of Health (NIH).
Most UAPs, including nursing assistants, are not certified to change sterile dressings, distribute medications, insert or remove any tubing (such as nasogastric tubes), or conduct tube feedings. Such tasks should be therefore left to the overseeing nurse or clinical licensed professional. [4] UAPs must be delegated responsibilities.
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
Another common form is a set of fingers that press on the tube in sequence. Small-volume pumps usually use a computer -controlled motor turning a screw that pushes the plunger on a syringe. The classic medical improvisation for an infusion pump is to place a blood pressure cuff around a bag of fluid.

Among others, ISMP maintains and disseminates a list of "do not crush" medications, [3] as well as clinical best practices. [4] The ISMP's Medication Safety Self-Assessment tool has been used in surveys of medication safety in hospitals in the United States and elsewhere. [5] [6] [7] [8]
Drip chambers at the bottom of each of two IV bags. A drip chamber, also known as drip bulb, is a device used to allow gas (such as air) to rise out from a fluid so that it is not passed downstream. It is commonly employed in delivery systems of intravenous therapy and acts to prevent air embolism. [1] [2]
