Effect of discharge current on cell voltage and power. When current is drawn from a cell, the cell volta ge falls due to polarization. The higher the current, the greater the voltage drop.
Topics | Critical Care | How is total parenteral nutrition (TPN) given? Total parenteral nutrition (TPN) is given through a vascular access device such as a Peripheral Intravenous line, Midline or most preferably a Central Line. The central line is the most common access for TPN administration.
They place a PICC, get a CXR. If they can't get the picc to thread to the appropriate place then it's left as a midline. You still need to verify it's placement (make sure it's not in the IJ or anything). It's not considered a central line. Also, you cannot run pressors or TPN through a midline.
