    Section 5 - Operation Monitoring System As trending proceeds past one hour, the trend display adjusts the time scale as follows: When the graph fills up with trend data, the trend dis- play creates a new time scale that carries over only the most recent 50 minutes of data from the previous graph.
  • Page 107: Oxygen Monitoring

    Section 5 - Operation Oxygen Monitoring Overview Inspiratory oxygen concentration is measured with a dual galvanic cell sensor which is attached to the inspiratory valve dome. The sensor works by taking in oxygen, which initiates an electrochemical reaction within the oxygen sensor. The oxygen monitor reads the voltage produced by this reaction and translates it into an oxygen concentration measurement.
