what does the medical term picc line mean
Peripherally inserted central catheter A peripherally inserted central catheter (PICC or PIC line), less commonly called a percutaneous indwelling central catheter, is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g., antihypotensive agents a.k.a. pressors). It is a catheter that enters the body through the skin (percutaneously) at a peripheral site, extends to the superior vena cava (a central venous trunk), and stays in place (dwells within the veins) for days or weeks.
Ammeter A picoammeter, or pico ammeter, measures very low electric current, usually from the picoampere range at the lower end to the milliampere range at the upper end. Picoammeters are used for sensitive measurements where the current being measured is below the theoretical limits of sensitivity of other devices, such as Multimeters.
