MAN 01/EN/03 CRONO PAR 50 06/13
POST-OCCLUSION BOLUS
When the occlusion alarm sounds, the pump has detected an excessive back
pressure in the infusion line. This back pressure must be removed in order to
avoid releasing a post-occlusion bolus, which might cause serious harm to
the patient. The volume of a CRONO PAR 50 post-occlusion bolus, conside-
ring only the combined volume of the pump and the reservoir, is:
• about 1.0 ml (PL1);
• about 1.2 ml (PL2);
• about 1.5 ml (PL3).
• The volume of the bolus dose released post occlusion can increase if there
is air in the line, if you are using catheters, lters and extension tubes of other
dimensions or of a softer material, or when the line from the pump is connected
to other devices.
• After the occlusion alarm sounds, take any and all measures appropriate to
avoid the administration of a post-occlusion bolus to the patient.
• Patients who might suffer severe harm from the accidental release of a post-
occlusion bolus must receive adequate instructions and/or training from medical
or paramedical personnel on how to proceed in such a situation.
