Sigma Spectrum Infusion Pump User Manual

CAUTIONCAUTIONbore catheters or needles may cause excessive backpressure at elevated flow rates.Please size the catheters according to expected flow rate and fluid viscosity.Follow Physicians OrdersFederal (USA) law restricts this device to sale or use by, on the order of, or under thesupervision of, a physician or other licensed healthcare practitioner.Single Fault ConditionsThe maximum downstream occlusion time due to a single fault condition (in seconds)may be determined by dividing 2448 by the flow rate in mL/hr.In the event of a downstream occlusion detector failure, the secondary detectionmethod will limit the pressure developed by the pump to 10 PSI above nominalsetting and generate an audible and visual alarm.A bolus of approximately 0.5 mL may be generated as a result of a single faultcondition.Air volume equivalent to 15 seconds of delivery may be delivered to the patient in theevent of a single fault condition. The amount of undetected air, in mL, is dependenton flow rate setting divided by 360. This air may not reach the patient depending ontubing length from the pump to the patient. One inch of tubing is approximatelyequivalent to .120mL of fluid.- 27 -
