The customer reported ¿air has been present below the ail sensor causing air-in-line alarm¿.Received from the customer was one used primary set model 2200-0500 lot unknown.Received with a copy of the customer¿s ¿return authorization¿ form.The set was visually inspected for kinks, incomplete bonding engagements, holes/tears in the tubing or damages to the components.Clear liquid was observed in the set¿s drip chamber and entire length of tubing.No abnormalities were observed during visual inspection.To prepare the set for functional testing a lab extension set was attached to the set¿s male luer.An 18 gauge cannula was attached to the end of the extension set to closely simulate how a set would be used in the field.Functional testing was performed by filling a lab iv bag with blue-dyed water and attaching the returned disposable set allowing the fluid to flow through the set via gravity following dfu.The set flowed freely and showed no signs of air being introduced into the line.The set was loaded into a lab pump module device with an air bolus limit set to 250¿l and accumulated air ¿enabled¿, as the customer did not provide pump module¿s air bolus limit and accumulated air settings.The primary infusion was programmed at a rate of 75ml/h and vtbi 75ml.The infusion completed with no alarms or any air-in-line issues noted by the device.No air bubbles in the tubing were observed and when the device door was opened after infusion was complete.The set was pressure tested while submerged underwater (per dir #10000360033 ¿ iv disposable leak test method).Air pressure was incrementally increased from 5 psi to 30 psi.No leaks or issues were observed on the set.Equipment used (inspection and testing performed on 19-aug-20) - air pressure regulator with pressure gauge eq00138, calibration due date: 02-oct-20 - optical ram-cnc, eq08204, calibration due date: 05-feb-21, - 8015 alaris pcu 1.5, eq08330, pm due date: 04-aug-21 ,- 8100 alaris system lvp, eq08327, pm due date: 15-nov-20, the device history record for primary set model 2200-0500 lot unknown could not be conducted because the lot information was not provided.H3 other text : see h10.
