Partial Volume Exchange Transfusion, Clinical Pathway, ICU
Partial Exchange Volume/Passes/Frequency
| Definition | Notes | Example |
|---|---|---|
| Total Volume of Blood to Exchange | Determined using equations specific to anemia or polycythemia | 75 mL |
| Length of Procedure | In general, PVET should be done over 30-45 minutes based on volume of blood being exchanged, hemodynamic stability of patient and access. Hemodynamic instability and/or peripheral access are considerations for using a longer length of exchange of 60-90 minutes. | 30 minutes |
| Length and Volume of Each Pass A pass is the amount withdrawn over a set interval of time. |
Use of passes ensures that the amount being withdrawn is equal to the amount being infused. Consider using 3-5 minutes as the pass time. |
30 minutes for entire exchange/5 minute pass time = 6 passes 75 mL/6 = 12.5 mL to be withdrawn over 5 minutes |
| Pump Rate Rate at which nursing will program the infusion pump in mL/hour |
75 mL/30 minutes = 2.5 mL/min x 60 = 150 mL/hr | |
| Volume to be Infused (VTBI) | Total volume entered into “VTBI” part of infusion pump by RN at start of each pass | 12.5 mL |
