A spacelabs field service engineer arrived onsite for further investigation.Findings show that the transmitter that was in use during the episode in question was unable to be located by the customer for testing.The remaining devices were tested by the fse and confirmed to perform to specification.The patient's historical waveforms and trend information were reviewed by a spacelabs lead software engineer.Findings show an episode of ventricular tachycardia (vtach) for the specified time period and that a corresponding vrun alarm generated.As the complaint episode had been appropriately classified and documented in the historical database and central monitor alarm indicators operated according to specifications when tested by a spacelabs field service engineer, we know of no reason that audible and visual alarm indicators would not have been present at the central monitor at the time of this complaint episode.This report is considered final and the issue closed.
