A catheter goes into the bladder through the urethra on the outside of the body. It is held in place by a bubble filled with water that is blown up after it is inserted. When inserting a catheter, you can confirm that it is in the correct placement and in the bladder when you see "urine flashback" (urine starts draining into the tubing).
One or more catheters is inserted through a peripheral blood vessel in the arm (antecubital artery or vein) or leg (femoral artery or vein) with x-ray guidance.
At the same time as the catheter is inserted, a second electrode is placed on the patient's skin.
