Because each patient's needs are unique, the Spectra Optia system enables you to customize the procedure based on each patient's specific characteristics.

2Calculation:
1/.87 = 1.15
3Calculations:
Anticoagulant volume = 1,000 mL/9 (inlet:AC ratio of 10 = 9 parts blood to 1 part AC) = 111 mL
Spectra Optia system: 100% − 87% = 13% of 111 mL = 14.4 mL AC/L processed
Assumptions: AC ratio of 10
NOTE: An AC infusion rate of 0.8 to 1.2 mL/min/L TBV was used during the clinical studies; however, it was not used directly in this calculation.
**Under normal operating conditions, the ECV will not exceed the typical ECV value. Under certain infrequent alarm conditions, such as during reservoir recovery after a reservoir alarm, the ECV may momentarily increase to the maximum ECV value.
