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.
Total TPN volume includes lipids 4. Keep the minimum dextrose/amino acid volume at 50 cc/kg for ordering purposes 5. Amount per kg as ordered on the TPN form DISCONTINUING PARENTERAL NUTRITION: PN may be stopped when the infant is tolerating â¥100-120 cc/kg of enteral feedings or is receiving â¤25 cc/kg/d of PN. Start amino acids at 2-3 g/kg/d, as much as possible depending on fluid allowance and access. The traditional step-wise advance of protein has not been found to be necessary and may be negatively affecting the infants' nutritional status. Advance by 0.5 gm/kg/d to goal as needed.
