What does the term "flush protocol" refer to?

The term "flush protocol" specifically refers to the method of clearing catheters using saline or heparin. This protocol is crucial for maintaining the patency of vascular access devices and preventing occlusions. Regular flushing helps to clear the catheter of blood and any potential clot formations, thereby ensuring that the catheter remains open and functional. The use of saline or heparin in flushing serves to both hydrate the system and provide anticoagulant properties, which further aids in the prevention of clot formation.

In clinical practice, these protocols outline the specific volumes and frequency of flushing, as well as the appropriate solutions to use, all of which are essential for optimizing patient care and maximizing the life of the vascular access device.
