A philips field service engineer (fse) went to the customer site.The fse tested the mx40, and found it was working with no issue, and verified the connection to the nearest network access point (ap).The fse was not able to test the pic ix at the time, however, the customer biomed confirmed with the philips complaint investigator (ci), that both the mx40 and piic ix involved were tested and verified to be working properly.The fse obtained alarm logs from the pic ix for this incident, which was verified to have occurred between 11:22pm-11:23pm on (b)(6) 2020.The alarm log was reviewed by the ci.An asystole alarm was seen to have occurred during this time at 23:22:57.Additional alarms occurred during this time, until 23:31:18 and the alarms were silenced; the asystole then ended at 23:31:31.The fse noted that the philips products were rebooted the next day.The customer also asked for activity from (b)(6) 2020 at 21:58 to (b)(6) 2020 at 22:49.Follow-up with the customer by a philips clinical specialist (cs) was performed.The customer indicated that they found no issues with the pic ix or the patient worn device (mx40); both devices remained in use.There was no product malfunction; this is considered a user issue.The pic ix alarm logs were reviewed, and the device alarmed for asystole, during the time it was alleged to not have alarmed; the alarm was eventually silenced.Additional alarms occurred after this event with reminders being sent, until the patient showed being transferred to another bed.No further investigation or action is warranted at this time.Submission of a report does not constitute an admission that medical personnel, user facility, importer, distributor, manufacturer, or product caused or contributed to the event.
