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.
PICC lines are central lines, the tip is usually in the lower third of the SVC. A midline is a peripheral line, with its tip distal to the shoulder. Since the tip of the midline is not in the central circulation, our hospital does not require a chest x-ray for confirmation of placement. Hope this helps...:spin:
