How do you prevent backflow in IV administration?When the cuff is inflated, there is no back flow of venous blood in the infusion line. During the cuff inflation, the pressure exerted by inflated cuff over the collapsible tubing of infusion set causes compression and total occlusion of the lumen and thereby prevents backflow of intravenous blood.

A saline lock – sometimes called a “hep-lock” in reference to how it used to be used – is an intravenous (IV) catheter that is threaded into a peripheral vein, flushed with saline, and then capped off for later use. Nurses use saline locks to have easy access to the vein for potential injections.

Fluid used for locking is often heparin or normal saline (a sterile solution of salt in water at a concentration suitable for the blood).
How much solution should you inject into an IV catheter to lock the device?
A uniform lock volume of 1.5 mL is recommended for all small catheters such as peripheral cannulas, midlines, PICCs, nontunnelled CVCs, and small bore tunnelled catheters. For large bore tunnelled catheters and TIVADs with a large reservoir, 2.5 mL is sufficient.
Do you flush a PICC line with heparin?

What causes backflow in IV?
The difference in pressure between the drip chamber and the venous pressure causes the reverse flow. To address the above issue, hospitals use a blood pressure cuff tied on the same arm where the infusion is given and, this cuff is inflated when backflow occurs.
What is IV infiltration?
IV infiltrations and extravasations occur when fluid leaks out of the vein into surrounding soft tissue. Common signs include inflammation, tightness of the skin, and pain around the IV site. IV infiltration is a common complication of intravenous (IV) therapy.
