ANNEX 2

TIME TO AN OCCLUSION ALARM SIGNAL

MAN 01/06/USA/p CRONO FIVE 11.10

There is a certain interval time between when an occlusion occurs and the

time it takes for the pressure in the administration line to trigger the occlu -

sion alarm signal. The table below is showing the time to an occlusion alarm

with different flow rates in combination with an infusion set with 27G need -

le, 80 cm lenght with very stif f lining.

The time to the occlusion signal is a function of the flow rate, the lower the

flow rate, the more time the pump will need to trigger the occlusion alarm.

CAUTION

The time to an occlusion alarm signal can increase if there is air in the line,

when other catheter sizes, filters and extension set tubing with softer mate -

rials are used, or when the lines from the pump are connected to other

access devices.

For patients that are likely to be adversely af fected by interrupted medica -

tion or fluid delivery from Crono Five, close supervision for immediate cor -

rective action should be provided.
