Etching. You can create a one-of-a-kind driveway with a technique known as etching. Patterns and designs are etched into your existing driveway with special tools to create a permanent design. The choice of designs includes stone patterns, special logos and graphics.
Depending on its size, you might not be able to obtain a blood sample from a peripherally inserted central catheter (PICC). For example, drawing blood from small-gauge PICC lines (2 or 3 French) can be difficult. Although sources vary, the Infusion Nurses Society recommends using the distal port of a multi-lumen catheter for blood sampling. The distal port is largest (16-gauge) and has a greater flow rate.
The catheter is pushed forward over the wire and into the aorta (the main blood vessel leading from the heart) and then into the kidney artery. The test uses a special dye (called contrast) to help the arteries show up on the x-ray. The blood vessels of the kidneys cannot be seen with ordinary x-rays. The dye flows through the catheter into the kidney artery. X-ray images are taken as the dye moves through the blood vessels.
