refers to the state of being open, expanded, or unobstructed. In a medical context, it specifically describes the functional openness of a bodily passage (like an airway or blood vessel) or a medical device (like an IV catheter or stent).
: Ensure the catheter tip is in the ideal anatomical location (e.g., the lower third of the superior vena cava for central lines) to prevent clots.
: Flush lines regularly with 0.9% sodium chloride using a "pulsatile" or "stop-start" technique.
Because patency is critical across various fields, follow the specific guide below relevant to your needs: 1. Vascular Access (IVs & Catheters)
Maintaining patency in intravenous lines ensures medications are delivered safely into the bloodstream without leaking into surrounding tissue (infiltration).
: Confirm patency by checking for easy aspiration (brisk blood return) and easy injection (flushing without resistance). Maintenance :
: Always use clean, closed systems to prevent blockages caused by pathogens or debris. 2. Gastroenterology (Patency Capsule Test) Patency capsule - patient instructions
