10.2.4 Error E4: OCCLUSION

If an error E4: OCCLUSION occurs, immediately check
your blood glucose level, because insulin delivery has
been interrupted. If your blood glucose level is high,
take appropriate actions according to your doctor's or
healthcare team's instructions.
An error E4: OCCLUSION occurs if insulin (a maximum of 3.5 units of
insulin when using plastic cartridges or a maximum of 6 units of insulin
when using Aventis Insuman Infusat glass cartridges*) is failed to be
delivered. This may be caused by:
– a blocked infusion set or
– a reused cartridge or
– a dirty or damaged piston rod.
This error is dependent upon several factors including your current
hourly basal rate and boluses. For example, a blocked infusion set –
with a basal rate of 2.0 U/h (no additional boluses) would have an error
E4: OCCLUSION in approximately three hours or less using Accu-Chek
3.15 ml plastic cartridges, depending on the type and severity of the
blockage.
* Insuman ® Infusat produced by Aventis Pharma Deutschland GmbH, a member and a brand
of the sanofi-aventis group.
