Figure 1-5
Dose and bolus (P+P mode) infusion pattern (does not apply to the PIB-IL
v1.5
)
Boluses are available after a lockout time. In the example used in Figure 1-5 and Figure 1-6,
the dose volume is 20 ml, the dose interval is 90 minutes, the bolus volume is 10 ml, and the
lockout time is 30 minutes.
Automated doses are scheduled at a set interval. An optional dose is available at the start of
a new infusion if the BOLUS button is pushed within 60 seconds. Unlike in PCA mode, if the
BOLUS button is not pushed, the bolus is NOT available until the lockout time has expired.
If a bolus is requested and delivered, the lockout time may delay the dose until the lockout
time has expired. A lockout time occurs immediately after either a bolus or dose
12
. The third
dose in Figure 1-5 has been delayed by a little over five minutes, so instead of occurring at the
180-minute mark, the third dose occurs at about the 185-minute mark. The dose stays delayed
for the rest of the therapy.

The purpose of the lockout time is two-fold: (1) to allow the medication to work before the patient can receive additional
medication and (2) to space out doses and boluses to prevent the patient receiving a harmful amount of medication.
