    Systems with the Arrhythmia Analysis module calculate heart rate using multiple ECG leads and arrhythmia analysis algorithms. The Acuity System is not directly connected to patients. It is designed to be used as a central monitoring system for a set of patient monitors that support both continuously and intermittently acquired data.

  • Page 7: General Warnings And Cautions

    Acuity System alarms, alerts or other events can go unnoticed if clinical personnel are not present at the Acuity Central Station or if interruptions occur in power or system operations. You are responsible to provide percent reliable power to the central station.
  • Page 8 With the exception of the Welch Allyn 1500 monitor in a disconnected state, which provides its own LTA analysis and alarm, the central station is the primary source for LTA analysis. LTA alarms will occur at the central station and will also be communicated to the bedside monitor for annunciation.
  • Page 9 Related to monitoring interruption WARNING If you view an Acuity System display remotely and its primary Acuity System fails, you lose all access to the remote display. Monitoring a patient at an Auto-Open Secondary (AOS) or Patient List Review (PLR) remote station is not a substitute for monitoring a patient at the primary Acuity Central Station.
  • Page 10 Welch Allyn Acuity Central Monitoring System WARNING Whenever an interruption in Acuity System CPU operation occurs, please contact Welch Allyn Technical Service soon to ensure that your entire system has returned to normal operating condition and that it does not require further service.

  • Page 80 The current beat for each ECG lead becomes the reference beat, and the deviation value for each current beat becomes zero. 4. Closely examine the current ST segment for all active leads to ensure that the Acuity System has defined an appropriate ST analysis reference beat.
  • Page 81 WARNING The ST algorithm has been tested for accuracy of segment data. As with all computerized ST analysis systems, the Acuity System cannot replace skilled care and proper surveillance by a clinician. A clinician must review all data obtained from the Acuity System, including the significance of ST-segment changes, before implementing therapy based on this data.
