If a central venous access device is present, the health care provider, whether a primary care provider, specialist, or emergency provider, will have a heightened awareness of the problems that can occur. The provider will ask about symptoms and perform a physical examination.

Some of the following tests may be performed:

• Chest x-ray - Evaluates for improper device placement or complications such as pneumothorax or hemothorax



• Blood draw - Checks for infection



• Ultrasound exam of the arm vein - Performed if a clot is suspected



• Nuclear imaging study - Confirms that the device is properly placed and still working and/or excludes blood clots in the lungs
