Alaris™ Syringe Pumps
Occlusion Pressure Limits
Occlusion Pressure Limits
Time to alarm following occlusion is achieved in less than 30 minutes at rates of 1 ml/h and higher by the appropriate selection of
occlusion levels .
Use of the dedicated pressure set is recommended for the Alaris CC Syringe Pump and the Alaris CC Guardrails Syringe Pump . Its use
permits the occlusion alarm pressure (mmHg) to be set accurately, with a small operating margin between the alarm and normal
infusion pressures . When using infusion pumps without a pressure set, line pressures are estimated from pumping force . For this reason
the occlusion alarm needs to be set with an operating margin of at least one level between the alarm and normal infusion levels . The
ability to set a small operating margin permits short time to alarm and small potential bolus volumes to be achieved . Bolus volumes can
be minimised as described in the Alarms and Warnings - Occlusion or by enabling the back off general option .

Occlusion
• Occlusion level on Alaris GH Syringe Pump or other pumps with
occlusion levels: L2 (approx . 200 mmHg) .
• Auto pressure setting on Alaris CC Syringe Pump: (e .g . 55 mmHg) .
• T1 << T2 .

The following graphs show the typical values for time to alarm and bolus volume that can be expected in the event of an occlusion
when the BD Plastipak 50 ml syringe is selected with a G30402M extension set with occlusion sensing disc .
