Event or Problem Description
According to the complaint information, during the event of administer rescue breaths to a patient in distress, the spur ii did not depress properly.It was checked that the ambu mask was properly placed multiple times, as well as checking the connection to the oxygen flowmeter.The spur ii was thrown away and another spur ii was opened with the same issue.Per customer: there did not appear to be any deformities to either bag.Everything appeared to be as it should be.When placed on the patient's face we checked several times for a good seal between ambu mask and the patient, a good seal was made, however when we squeezed the bag, we could not push air at all.We couldn't hear any air, nor could we see chest rise and fall, this happened with both bags.Too much time was spent trying to get it to work and therefore the anesthesia team asked that we discontinue use and order a different brand.The patient did stabilize despite the malfunction of the ambu bag.
Additional Manufacturer Narrative
Field d4 - only primary di number included, no pi number, as lot is unknown.No samples or pictures could be returned for investigation due to the affected two samples had been discarded after event.Ambu spur ii has been verified to be able to be depressed, and to re-expand to its default shape by itself during manufacturing.All spur ii are function tested according to process control procedure to make sure the finished product meets design specification.Therefore, it should be easily detected if the spur ii could not be depressed properly during manufacturing.After reviewing relevant production records, it has not been possible to identify any abnormalities which could cause the reported failure.Both spur iis should be within specification before delivery.Per event description, it seems the affected spur iis were blocked somewhere, so that air could not be pushed and the compressible bag could not be depressed.One possible cause is patient valve disc stuck or was not installed correctly and therefore could not move during ventilation.The other possible cause is that face mask was connected with oxygen flowmeter during the event which may increase the inspiratory resistance and affect air delivery to patient.We have tried to confirm this information with the customer but no reply received.Due to limited information, the root cause could not be defined.The ifu (492 2300 31 - v17 - 2024/04.Tcc 11599) states under the section cautions: "always inspect the resuscitator and accessories (e.G.Face mask, peep valve, filters, etc.) and perform a functional test after unpacking, cleaning, assembly and prior to use".
