Calculating the Catheter Volume
The precise catheter model number, implanted catheter length and
pump model number are of critical importance in preventing a drug
under- or overdose when calculating and programming a
Postoperative Priming Bolus. Calculating and programming a
Postoperative Priming Bolus without precise information may result
in a clinically significant or fatal drug under- or overdose. A
universal value does not exist which can be used as a substitute for
this knowledge.
1. Identify catheter model.
2. Determine length of implanted catheter and record in patient's records.
Subtract the discarded length from the catheter length. Refer to the
appropriate catheter technical manual for catheter length.
CAUTION: If catheter is trimmed at implant, the implanted length must
be used in the Catheter Volume formula.
3. Determine volume per cm (inch) in catheter. Refer to the appropriate
catheter technical manual for the volume µl/cm (inch).
4. Substitute the values from Steps 2 and 3 into the formula below to determine
the catheter volume. Refer to the appropriate catheter technical manual for
specifications. See example below.
Catheter Volume (ml) =
[Catheter Length – Discarded Section cm (inches)] x Volume µl/cm (inch)
