Details of complaint: the biomedical engineer (bme) reported that the telemetry transmitter missed a vtach alarm at the central nurse's station (cns).No patient harm was reported.Investigation summary: alarms are triggered by limits configured in the device's alarm settings.Devices are configured as per customer requirements by the nk clinical staff at the time the devices are taken live.Additional changes to device settings can be made post "go-live" by the customer based on the facility's policies, protocols, and processes.The root cause cannot be determined.The customer did not provide device logs after 5 days of the request.Logs relating to the event can no longer be obtained.A complaint history review of the reported device revealed no subsequent complaints relating to missed alarms.It is likely that the customer changed alarm settings to resolve the issue.It is also possible that the alarm was silenced or ignored.As the customer did not provide the needed information to confirm the issue and there has not been a recurrence, further action is not warranted.Telemetry transmitter : model: zm-530pa.Sn: (b)(6).Device manufacturer date: 11/25/2021.Unique identifier (udi) #: (b)(4).Returned to nihon kohden: not returned.
