6.8.10.2
Vaporizer Accuracy Test
WARNING: Avoid exposure to respiratory gases by always directing
the fresh gas flow from the fresh gas outlet to the waste gas
scavenger.
1.
Remove the Fresh Gas Hose from the Common Gas Outlet.
2.
Insert an endo-tracheal tube mask elbow adapter with monitoring port, into the Common
Gas Outlet.
3.
Set the APL Valve to
70
cmH
2
O.
4.
Remove the Waste Gas Scavenger Hose from the bottom of the Breathing System EVAC
port. Leave the connection to the waste gas scavenger attached.
5.
Set the waste gas scavenger flow above the minimum setting.
6.
Adapt the Waste Gas Scavenger Hose to connect to the endo-tracheal tube mask elbow,
now connected to the Common Gas Outlet port.
7.
Attach the Agent Analyzer meter sampling tube to the endo-tracheal tube mask elbow's
monitoring port.
8.
Fill the vaporizer with anesthetic agent (if necessary).
NOTE:
Do not overfill by filling past the indicator line on the
vaporizer.
9.
Test the vaporizer accuracy per the Dräger Vapor 2000 instructions (See
section 6.8.10.4), or see the appropriate vaporizer manual for testing details.
10.
Test each vaporizer in turn.
11.
Test any vaporizer on the Vaporizer Storage Mount.
12.
Remove the measuring equipment from the Common Gas Outlet.
13.
Reconnect the Fresh Gas, and Waste Gas Scavenger Hoses.
6.8.10.3
Vaporizer Leak Test
NOTE:
Verify the system has passed the leak test without the
vaporizers prior to this test.
1.
Verify that vaporizers are mounted correctly.
2.
Ensure that the gas pressure for O
2
, N
2
O, and AIR are at 50 ±10 psi.
3.
Power ON the
4.
Attach a reusable-silicone-rubber breathing circuit to the Breathing System.
NOTE:
For testing purposes always use a reusable breathing
circuit.
5.
Tightly connect the Y-fitting on the breathing circuit to the test port.
6.
Attach a breathing bag to the bag arm.
7.
Set the APL Valve to the fully closed position (
70
cmH
2
O).
8.
Rotate the O
2
Flow Control Valve until 50 cmH
2
O pressure is observed on the Airway
Pressure Gauge.
9.
Verify that the necessary flow to stabilize the pressure is less than 300 mL/min.
