URINARY CATHETER CARE - cnaZone

In-dwelling urinary catheters are long, narrow tubes made of latex or silicone. The size of urinary catheters is measured using the French system: this is typically abbreviated as Fr. Most in-dwelling urinary catheters are size 14, 16 or 18 French, but larger or smaller ones can be used. Urinary catheters have two passages called lumens. ................
