The Flow Sensor Calibration needs to be performed each time:
• A new sensor is put in place.
• After device startup
• After enabling the flow sensor (manual and automatic)
• After patient range change (Note: the sensor type must
match the patient range selected)
• After reconnection of a flow sensor resolving a disconnection
alarm
We recommend cleaning the Flow Sensor once daily.
If zero flow and tidal volume measurements are detected in numeric and graphs
after:
• Disconnection
• High Leaks
• Low-level Rain-out
• Over-breathing
Flow measurement will be automatically re-started after 6 seconds.
If flow and tidal volume measurements are not regained,consider the following:
• Checking ET tube position (high leaks at the patient) and
blockage (during or after in-line suction, or after surfactant
therapy)
• Flow Sensor Leakage (loose flow insert or leak)
• Flow Sensor Contamination (single-use sensor
recommended)
• Rain-out (contact ACUTRONIC Medical Systems sales for
recommended Patient Circuits and Humidifier to prevent
Rain-out)
The O
2
sensor calibration can be accessed in the Configurations menu, by
pushing the O
2
button.
The O
2
sensor is automatically calibrated when the machine starts up and every
24 hours when in use.
During Calibration procedure, the FiO
2
concentration of the fresh gas to the
patient is NOT altered.
• In case of a “supply Gas failure”, the oxygen sensor calibration is
automatically disabled to avoid false sensor calibration.
