Manufacturer Narrative

The provided information, photos and log files were reviewed by draeger service engineering and product management.Investigation determined that the m540 and the associated infinity central station (ics) functioned as intended.A network disconnection between the m540 and ics occurred around the time of the event.While the m540 disconnected from the ics the m540 continued to monitor the patient/provide alarms for limits set and automatically increased its volume to 100% as intended.When the m540 disconnects from the ics, the ics displays that the bed is disconnected to alert the user, however the site could not verify this for the event as the site indicated that all nurses were at patient bedsides during the event and nobody was allocated to sit at the ics.When the m540 came back online it was confirmed that the ics displayed the asy alarm.As indicated by the site, the ics was not being actively monitored as needed and the nurses were occupied at other patient's bedsides.There is no indication a draeger device malfunction occurred.The ifu provides the following warnings in relation to monitoring the ics and disconnected conditions: warning the user must remain within the hearing range of the acoustic alarm signal.This operator position makes it possible to quickly detect an alarm and to respond accordingly.The distance to the medical device must be appropriate for the volume of the alarm signal.Warning loss of communication between the ics and a monitor is possible.If the ics loses communication with the infinity network, an audio alarm signal sounds at the ics and displays a message indicating that the bedsides are offline.The bedside monitor displays a message indicating an offline condition.Draeger recommends using the bedside monitor for primary diagnosis and the ics for patient viewing.H3 other text : the involved ics is working and remains in use according to the hospital biomed.
