Bolus Volume
The recommended minimum bolus volume is
1 mL or 10 percent of the syringe volume of the
syringe used, which ever is less. In other words, for
a 1 mL syringe (regardless of the actual volume of
medication contained), the minimum recommended
bolus volume is 0.1 mL. For a 60 mL syringe, the
recommended minimum bolus volume (regardless
of the actual volume of medication contained), is
1 mL. Bolus volumes delivered that are less than
the recommended minimum bolus volumes for the
syringe used may result in delivery inaccuracies.

Use appropriate internal
diameter tubing
For the most consistently precise control of all
fluids and medications, it is recommended to use
appropriate internal diameter tubing , as well as to
minimize residual volumes between syringe and
patient by reducing:
a) Tubing internal diameter (generally, for rates
under 5 mL/hr small internal diameter tubing
is recommended; for rates 5 mL/hr or above,
tubing with a larger internal diameter should be
used to reduce occlusion alarms)
b) Tubing length
c) Size of in-line filters
d) Number of stopcocks
This makes the infusion setup less variable or
compliant, which in turn reduces the start time for
fluid to reach the patient – and reduces time required
for detecting an occlusion and maintains delivery
accuracy.
Use only the standard syringes specified on the
table on page 128 and supplied with PharmGuard
®
Toolbox 2, or supplied with the PharmGuard
