After the reported event, the affected device was checked by a draeger service technician who also downloaded the electronic log file.As the logfile had already been overwritten a case-specific analysis was not possible.Our service technician was not able to reproduce the reported sticking because the breathing system which includes the peep-relevant components had already been reprocessed and could no longer be identified which may result from unwanted tension within the peep valve diaphragm, which can result from an unfavorable assembly of the peep valve.In this context draeger introduced improved assembly instructions end of 2012.The affected device has already been repaired accordingly.The amount of similar cases is significantly below the values that provide basis for our risk management.Consequently, no further actions are required at this time.
