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.
What you said about TPN/PPN makes sense, and I'm pretty sure that the orders to say Total and Partial. Why, then, can PPN go through a peripheral line? Is it a concentration thing? All I know is that it's a really big deal that you can't give TPN through a midline, and I just can't seem to grasp why that might be.
