MAN 01/EN/03 CRONO PAR 50 06/13

POST-OCCLUSION BOLUS

WARNINGS

SECTION 7

INFUSION SET OCCLUSION

The pump is designed to recognise when the administration

of a drug has been interrupted by external means, such as,

for example, the kinking of the infusion set tube and the

consequent occlusion.

In these circumstances, the pump stops the infusion: the

display indicates that there is an occlusion, accompanied

by a brief beep. The pump then continues beeping every

10 seconds.

While the system is still occluded, the drug is not

administered: to recommence the infusion, press the

button after having removed the cause of the occlusion.

• The cause of the occlusion is to be found along the infusion line and at the

point of injection.

• To avoid or reduce the incidence of occlusions, you are advised to use an

infusion set with anti-kinking tubes.

NOTES

The occlusion alarm is given when the pump detects excessive back pressure

in the infusion line. This back pressure must be removed without releasing a

post-occlusion bolus, which could cause serious harm to the patient.

The volume of a CRONO PAR 50, post-occlusion bolus, considering only the

combined volume of the pump and the reservoir is about 0.9 ml (in PL2 mode).

• The volume of the bolus released after an occlusion can vary, depending on

the infusion set and all the other components that comprise the infusion line.

• Another element that could affect the volume of the released bolus after an

occlusion is the presence of any air in the system.

• After the occlusion alarm is given, take any and all measures appropriate

to avoid the administration of a post-occlusion bolus, such as, for example,

disconnecting the infusion set from the patient.
