Preuse Checkout
Preuse Checkout
Procedure
Perform the following abbreviated checkout procedure when the
Narkomed 2B is used in successive cases. It may be performed only after
the initial daily checkout procedure given in Section 3 was performed.
This is a recommended procedure. Follow your institution’s policies
regarding specific checkout procedures. If the anesthesia system fails
any procedures identified by an asterisk (*), do not use the machine.
Contact a North American Dräger qualified technical service
representative for inspection of the unit.
NOTE: Do not insert any additional components into or modify the
anesthesia system after the checkout procedure is started.
Reserve Power
Verification
*1. Check the reserve battery power. Make sure that the SYSTEM
POWER switch is turned to the ON position. Remove the power
plug from the outlet. Press the BATTERY TEST button on the
main switch panel. The green indicator to the left of the test
button must light. The yellow BATTERY LOW indicator must
remain unlit. Plug the power cable back into the electrical outlet.
NOTE: This test assumes that the anesthesia machine has been
plugged in for 16 hours. The battery charging system
works only when the machine is connected to an active AC
power source. The charging system takes about 16 hours
to charge a fully discharged battery.
Bain Circuit Adapter
Verification
*2. Verify that the inner tube of the Bain circuit is intact and not
occluded. First deliver a flow of oxygen to the Bain circuit
through the fresh gas hose. Then occlude the inner tube of the
Bain circuit. The oxygen flowmeter float should drop in response
to the occlusion.
As an alternate test, press the oxygen flush button with the Bain
circuit’s patient port open to the atmosphere. The high flow of gas
through the Bain circuit’s inner tube will draw in gas from the
outer tube. As a result, the breathing bag should deflate. If the
breathing bag does not deflate or it inflates, the fresh gas hose or
inner tube may be improperly connected.
Absorber System
Verification
*3. To check the absorber system:
A. Check the hose connections in the breathing system.
B. Make sure the fresh gas hose of the breathing system is
securely connected to the fresh gas outlet.
