Air in line detection
Single Bubble (configurable): 50µl, 100µl, 250µl and 500µl .
Bubble accumulation: 1ml over a 15 minute window .
Air in line detector accuracy is ±3% .
Critical Volume
The maximum volume infused following a single fault condition is for rates < 10ml/h: ±0 .25ml, rates < 100ml/h: ±0 .5ml,
rates ≥ 100ml/h: ±2ml
Alaris™ Safety Clamp
Set based, Pump activated Safety Clamp device to prevent free flow

2 .
The system accuracy will change by the following percentages:
3
Temperature: nominally −5 .7 (±1 .5)% at 5°C and nom0 .3 (±1 .7)% at 40°C
Fluid Head Height: nominally −3 .4 (±1 .3)% at −0 .5m and 0 .0 (±1 .1)% at +0 .5m
Duration: nominally −1 .1 (±0 .2)% over 24 hours of continuous use
Back Pressure: nom2 .0 (±1 .3)% at −100mmHg, −13 .4 (±1 .8)% at +800mmHg respectively
Atmospheric Pressure: ±5% at 25ml/h at 70 .0kPa
3 .
Tested using distilled water, 20% lipid, 50% glucose, 0 .9% normal saline and 5% alcohol solutions .
4 .
The occlusion pressure accuracy will change by the following:
Temperature: Low setting nominally 7 (±12)mmHg at 5°C and −24 (±17)mmHg at 40°C respectively
Normal setting nominally 4 (±16)mmHg at 5°C and −41 (±18)mmHg at 40°C respectively
High pressure nominally 4 (±14)mmHg at 5°C and −38 (±21)mmHg at 40°C respectively
5 .
Accuracy tested using infusion set 60793 .
The specified accuracy may not be maintained if the above conditions are not met – see notes 1 to 4.
