Teleflex has received additional information regarding the event.The customer reports that "the patient didn't received enough oxygen, so oxygen has been connected directly to the nasal cannula and saturation of the patient finally returned to normal, no further consequences.A review of the manufacturing event log shows no issues that may have contributed to any quality issues reported.All process parameters were within specification.In-process qa inspections show one non-conformance that has no impact on the quality issue reported.Non-conforming material was sorted for a defect, re-inspected, and found to be acceptable per internal specification.The customer returned an empty water bottle (lot 533167) and an 040 humidifier adaptor for evaluation.The water bottle showed the adaptor port was punctured and the trigger was removed.Upon visual examination, no occlusions or other defects to the water bottle and the adaptor were observed.The water bottle was filled approximately half full of water, the adaptor was attached to the water bottle, and the bottle/adaptor assembly was attached to a flow meter.Other remarks: air flow was adjusted from 0lpm to 10lpm.There was air flow at the spout of the bottle throughout the test.Based on the investigation performed, the reported complaint of "no oxygen flow" could not be confirmed.There were no issues found with the returned sample.
