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 tube (catheter) is then fed through the vein until the tip of the catheter is sitting in one of the large veins in your chest. A small tunnel is made in the skin for the tube to pass through and the other end is connected to the port. Correct positioning of the catheter is confirmed by fluoroscopy (using x-ray).
