Qn# (b)(4).One complete 1607 ventilator tubing set , long length, was received for investigation.Upon receipt the breathing set was visually inspected or any signs of abuse/misuse/damage.Nothing was noted.The ventilator tubing set was connected to an in-house lab leak tester and 60 +/- 3 cm/h2o of pressure was applied to the circuit.The iso standard states the maximum leak value cannot exceed 70 ml/min.The circuit leaked at rate.07 ml/min which is well below the required 70 ml/min iso standard.This value is also well below the required leakage rate for a neonatal circuit which is 30 ml/min.The device history record of batch number 74f1900167 was reviewed and no issues or discrepancies were found which could potentially relate to this complaint.No non-conformance reports were originated for the lot in question that can be associated to the complaint reported.The dhr shows that the product was assembled and inspected according to specification.Additional testing results reveal the ventilator tubing set leaks well below the assigned leakage rate for a neonatal set.The complaint of leakage has been confirmed, however the leakage rate is well below the assigned leakage rate for this ventilator tube set.
