[IPk] No Delivery alarms
With the Minimed pump, and possibly also with the Disetronic
(Please confirm, John?), the alarm occurs due to a build up of pressure against
some sort of blockage. In the Minimed this will normally occur at less that the
equivalent of 3 units of delivery..(I don't know the equivalent figure for the
Disetronic) So in Diana's case there may have been the start of a build up of
pressure before the bolus
If a blockage occurs you should check all the obvious things
like kinks, twists, etc. We have also had cases with both pumps where an early
blockage alarm has occurred when the syringes are not properly aligned in their
Never forget, however, that many blockages occur because of
problems at the site, either by blocking with tissue, or as the result of early
stages of a build up of irritation etc. If the blockage can be cleared once the
set has been taken from the site then this is an indication of a site problem.
Of couse with the sofset and silhouette it is impossible to re-insert so this
will always need a change of set.
One other point to check before filling your syringe make sure
that it moves quite freely.
