NOTE

The vaporizer has deviations due to change of barometric pressure (high altitude).
And the Riken F-211 gas analyzer also has deviations. When testing the vaporizers
using the Riken F-211 gas analyzer, the altitude can be ignored as the deviations
cancel each other out. If using a different gas analyzer, check the effect of change of
barometric pressure before using it in high altitude area.
4.9.4 Vaporizer Leak Test
1. Set the Auto/Manual switch to the Manual position.
2. Set the ACGO to the patient circuit (when configuring the ACGO).
3. Set the APL valve to the SP position.
4. Connect the manual bag to the bag arm port.
5. Connect the Y-piece of the breathing circuit to the leak test port and both ends to the
inspiratory/expiratory port.
Note: When the AG module is configured, the sampling line of the module sample gas should not
be connected to the Y-piece sampling port and ensure that the Y-piece sampling port is blocked.
6. Mount and lock the vaporizer onto the vaporizer mount. (Certain vaporizers need to be
set to at least 1% for correct testing. See the vaporizer manufacturer's manual for
details.)
7. Set the fresh gas flow to 0.2 L/min.
8. Set the APL valve to 75 cmH2O.
9. Press the quick oxygenation button so that the pressure on the PAW gauge increases
above 30 cmH2O
