  VistaSolution, physiological signal transmitter. A software graphical user interface for use by healthcare professionals to display physiological data collected by the wireless remote monitoring system in healthcare settings. This is a secondary, adjunct patient monitor and is not intended to replace existing standard-of-care patient monitoring.

  A healthcare provider (HCP) noticed a patient had a lowered historic SpO2 reading that the software should have triggered a notification to the care team, but no notification was found. A software defect was encountered causing the lack of notification. The defect could result in exposing a patient to potential hypoxia for a short window of time. The firm is correcting the software to bring the performance back into compliance with specifications.

  The adherence check generates a software error. Two issues occur as a result of the software error: 1) No adherence flag is generated for that day; 2) No task is generated for the date 14 days later. An error message is generated and forwarded to operations. Subsequently, for days in which no task was generated, patient will not get a reminder on the tablet to take a measurement. If the pa
