humidifier. Use the cap that comes with the tee adapter to seal
the pressure port on the exhalation valve.
Attach the reusable exhalation valve to the patient end of the
breathing circuit.
Attach one end of the exhalation valve drive line to the exhalation
valve and the other end to the Exh. Valve. connection located below
the Gas Output on the FLIGHT 50 Ventilator.
See Figure 49.
When using the FLIGHT 50 Ventilator built-in humidifier, plug the
temperature probe electrical connector into the Temp Probe
connection on the left side of the FLIGHT 50 Ventilator. Attach the
short wire plug into the elbow outlet on top of the humidifier. Attach
the long wire plug into the exhalation valve port.
5.3.1 Exhalation Valve Calibration
The exhalation valve needs to be calibrated before use.
To calibrate the exhalation valve prior to use:
Each time an exhalation valve is replaced or maintained it
must be calibrated.
1. Connect the FLIGHT 50 Ventilator patient breathing circuit to the
ventilator as instructed above.
2. Connect an adult (500 mL) test lung or occlude the patient connection of
the breathing circuit.
3. Press the
On/Standby
button once to enter Settings condition.
4. Press the
Manual Inflation
button once, then again within three seconds.
5. The FLIGHT 50 Ventilator will start the EZ Cal and the ventilator will
automatically test the exhalation valve. If it passes the test, the
messages "
Cal Completed
", then "
Press ON to Vent
" will be displayed.
6. If the test fails, the message "
Cal Failed
" will be displayed.
Press the
Silence/Reset
button.
If using a test lung during the EZ Cal, remove the test lung and
occlude the patient connection instead.
Check the integrity of the circuit and connections, then press the
Manual Inflation
button twice to initiate calibration again.
7. When calibration is finished, adjust patient setting appropriately, then
press
On/Standby
to begin ventilation.
Inadequate ventilation may result if the exhalation valve is
not calibrated properly. If the circuit/exhalation valve fails
the calibration procedure, try another circuit/exhalation
valve or use an alternate method of ventilation.
