![]() Hemodialysis catheters: can be a long-term CVL or a short-term CVL.Long-term CVLs: e.g., PICC lines, tunneled CVLs, surgically implantable catheters.Sheath introducer (large gauge): used for rapid or high-volume fluid administration, or to aid insertion of other lines (e.g., Swan-Ganz catheter).Small gauge: decreases the risk of vessel thrombosis.Single-lumen CVL: 1 channel allows administration of a single solution at a given rate.Double-lumen CVL: 2 channels typically large gauge that allows high rates of fluid exchange, e.g., for hemodialysis or plasmapheresis.Triple-lumen CVL: 3 channels allows simultaneous administration of multiple solutions at different rates.Short-term CVLs: nontunneled CVLs typically intended to remain in place ≤ 14 days.Higher risk of pneumothorax than IJ line. ![]()
