Appendix C: Intravenous fluid additive calculations to prepare 1000 mL
The volumes below are calculated to allow for the average volume contained in 1000 mL intravenous fluid bags. For fluid additive calculations of fluids differing from those listed below please contact the pharmacy department.
*Note change in strength of concentrated sodium chloride; refer to previous editions or contact pharmacy if this strength is unavailable.
