The biomedical engineerreported that waveform displays on the gz transmitter but does not display on the central nurse's station (cns).They stated that this exchange unit had no issues prior to (b)(6) 2021.The ecg waveform were good, and the cns showed a good ecg waveform for a few seconds and blanked out with no lines or anything.This process would repeat.They had tried stopping monitoring and then starting monitoring and new batteries.No leads attached (will follow up with customer on this one).No physical damage / fluid intrusion.Auto ip.Auto on wireless band, but it should be 5ghz band.Stopped communicating with server on (b)(6) 2021.Then the customer put a telemetry transmitter on patient and was unable to transfer patient data to another gz.They were unable to discharge patient for a while but eventually got it to discharge from the box itself.They readmited the device to move patient data to different gz.They compared settings between this transmitter with a known working transmitter and everything was exactly the same.The failed gz showed changes once he got it to discharge, but the cns does not.There are communication issues between this gz and the cns.The customer does not know if there was a signal loss or comm loss error displayed on the cns when the ecg data was unable to be displayed on the cns from this transmitter.No patient harm reported.Nihon kohden continues to investigate the reported event.Nihon kohden will submit a supplemental report in accordance with 21 cfr section 803.56 when additional information becomes available.
