Philips received a complaint on the avalon fm30 fetal monitor indicating that there were no traces nor alarm for 40 minutes.The complaint was escalated for technical investigation, and the provided information was reviewed by a product support engineer (pse).The pse advised that the last time the us transducer reported a valid fetal heart rate (fhr) was at approximately 12:54:30.One minute later, a ¿signal loss¿ for fhr1 (rcf1) was issued from the fetal monitor (12:55:32), which is a visual and audible alarm.This alarm was acknowledged by pressing ¿silence¿ 19 seconds later, at 12:55:51.When an alarm for the loss of the fetal heart rate (e.G., ¿fhr1 signal loss¿) happens, an audible and visual alarm appears on the screen.In case the audible alarm is acknowledged, it is silenced, but the visual alarm is still visible on the screen of the fetal monitor.The visible alarm only disappears once the signal gets recovered.Based on the information available and the testing conducted, the device was functioning as intended, and there was no trouble found with the device.The reported problem was not confirmed.The device was confirmed to be operating per specifications and no failure was identified.
