11. Calibrate oxygen analyzer using 100% O
2
from cylinder or pipeline if available. NOTE: If cylinder or pipeline do not deliver
100% O
2
, only calibrate on room air as described below in
11c.
a. Using 100% cylinder/pipeline oxygen, set oxygen flowmeter to 6 L/minute and wait for maximum reading on
monitor.
b. Press CAL, then O
2
, then GO. When the calibration is finished, press EXIT twice.
c.
Turn off the oxygen. Draw room air through the system with the bellows until the reading reaches its lowest value.
d. Press CAL, then AIR, then GO. When the calibration is finished, press EXIT twice.
12. Calibrate apnea alarm pressure transducer as follows:
a. Make sure flow dials are set to zero flow and reservoir bag is empty
b.
Press CAL, then PRESSURE: CAL, then GO. When the calibration is finished, press EXIT twice.
13. Turn on oxygen concentrator using the selector switch on the front of the machine. Set the oxygen output to 6 L/minute
and ensure that oxygen reaches at least 90 to 95% output after a few minutes.
14. If using nitrous oxide, check the function of the Nitrous Oxide cut off at 25% oxygen concentration as follows:
a.
Set oxygen flow to 6 L/minute.
b. Set Nitrous Oxide flow to 4 L/minute.
c. Gradually reduce the oxygen flow to decrease the delivered O
2
to 25% and lower—nitrous oxide flow should cut off.
15. Fill the vaporizer to maximum with correct anesthetic agent. See the directions in the User Manual. WARNING: Do
not overfill the vaporizer. Do not spill agent on to the UAM, especially on to the oxygen sensor. UAM Configuration
A
has the oxygen sensor in front. Cover the sensor with a protective cloth when filling the vaporizer on UAMs with this
configuration. Refer to the fill level window.
16. Place all manuals and training materials in drawer and secure a location for extras, such as the additional oxygen sensor,
spare balloons, and so forth.
NOTE:
High levels of relative humidity in the environment will affect the performance of the UAM. It is recommended that
the UAM be used in areas where the humidity can be controlled. After operating the UAM in humid environments water
drainage should be observed underneath the machine once the concentrator is turned off and has depressurized.
IF YOU HAVE PURCHASED THE PATIENT VITAL SIGNS MONITOR:
1. Unpack monitor and insert the battery. The battery is in a white box inside the foam protectors holding the monitor
securely in the cardboard box.
2. Mounting the monitor: Please refer to the mounting instructions for the particular model of monitor obtained.
3. Connect patient cables to monitor – NIBP, SPO2, TEMP and ECG
4. Connect mains lead from monitor to one of the three prong sockets on the back of the UAM.
5.
Allow patient monitor and analyzer screen batteries to charge for 24 hours.
