This module cover common errors related to the physical set up of secondary infusions and the importance of checking your set up above the pump. In particular, this module covers:

• Hydrostatic pressure principles in relation to the set up of secondary infusions
  
• The importance of the back-check valve in preventing backflow
  
• How secondary flow rates may affect the set up requirements of secondary infusions
  

Note: Most of the content in this Module is focused on secondary IV infusions administered by infusion pumps that require the secondary container to be hung higher than the primary container (i.e., pumps that cannot independently control fluid flow from secondary and primary bags).
