3.2.3 P+PMode
P+P stands for patient-intermittent bolus (PIb) combined with patient-controlled analgesia
(PCA). This mode contains dose volumes occurring at set intervals, as well as optional boluses.

The bolus has units of milliliters (ml).

a dose is referred to as a programmed intermittent bolus (PIb) or as a
programmed intermittent epidural bolus (PIEb)

. In this manual, the term
“dose” will be used when discussing either PIb or PIEb. The dose has
units of milliliters (ml).

common than PIB or PIEB.
