NOTE:
The total volume is controlled by the IL over the dose interval. This means it is
possible for the bolus and dose to be delivered back-to-back (i.e., the bolus at the
end of one dose interval and the dose at the start of the next dose interval).
NOTE:
From the start of one dose to the start of the next dose (dose interval), the IL
is maintained, but over a time that covers the end of one dose interval and the
start of the next dose interval, the volume set for the IL may be exceeded. (This
situation is shown in Figure 1-7. The total volume infused from the time the
bolus is started at the end of the first dose interval to the time at the end of the
first bolus in the second dose interval, may exceed the IL. See Figure 1-8 below.)
