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.
With this protocol, most pa-. tients can tolerate large amounts of. TPN solution. A malnourished patient. may receive up to 3 liters per day of. hypertonic solution, or 2,500 calories. Accurate titration is aided by the use. of an intravenous (IV) pump.
