EFFECTS OF ELEVATION/BAROMETRIC
PRESSURE CHANGES
This device does not automatically compensate for changes in
barometric pressure. Calibration of the Analyzer shall be performed
when elevation at which the device is being used changes more than
500 feet.
EFFECTS OF TEMPERATURE
To minimize temperature effects:
1. In a breathing circuit, place the Oxygen Sensor upstream of
the heater.
2. Allow time for the Oxygen Sensor to stabilize to its new
room temperature.
3. Perform the calibration procedure at a temperature close to or
similar to your clinical application
EFFECTS OF HUMIDITY:
High Moisture levels will dilute the oxygen concentration, decreasing
the concentration of oxygen being monitored by the Oxygen Sensor.
High humidity can cause condensation to collect on the Oxygen
Sensor, obstructing the passages and reducing the effectiveness of
the Oxygen Sensor.
Ø
A calibration gas flow to the Oxygen Analyzer of two liters
per minute or more is recommended to minimize the
possibility of obtaining a “false” calibration value.
3. Allow the oxygen to saturate the Sensor. Although a stable value
is usually observed within 30 seconds, allow at least two minutes
to ensure that the sensor is completely saturated with the
calibration gas.
4. If the Oxygen Analyzer is not already turned on, do so now by
pressing the Analyzer “ON” button.
5. Press and hold the Cal button on the Oxygen Analyzer for at
least 3 seconds to activate calibration. The Analyzer will detect a
stable Sensor signal. When obtained, the Analyzer will display the
assumed calibration gas on the LCD.
