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.
A small plastic tube called a sheath will be placed into one of your arteries. A catheter (a long, thin flexible tube) is inserted through the sheath and on to the arteries being examined. Depending on the area being examined, the catheter is usually inserted into an artery in your wrist or groin. X-rays are used to help guide the catheter to the right place. Contrast agent will then be injected through the catheter and a series of X-rays will be taken.
