Anesthesia Machine Check Flashcards
Step 1: O2 equipment
Verify that back-up ventilation equipment ( self-inflating Ambu bag and O2 tank) are available
Step 2: E-cylinder Check
Check the E cylinder supply and make sure it has 1000 psi
- disconnect wall supply
- close the tank on the back (clockwise)
- press the O2 flush valve (if pressure decreases, we have verified that E cylinder system works
Step 2
Check the E cylinder supply and make sure it has 1000 psi
Step 2
Check the E cylinder supply and make sure it has 1000 psi
- disconnect wall supply
- close the tank on the back (clockwise)
- press the O2 flush valve (if pressure decreases, we have verified that E cylinder system works
Why did we close the E cylinder valve to verify that it worked?
We did this because if it were open while we hit the O2 flush, it would take a lot of time to see the pressure gauge come down. This would also waste a lot of backup O2, and we’d have to replace it frequently.
Verify the E-cylinder at least half full:
open the E cylinder (counterclockwise) and watch pressure go to at least 1000 psi
Step 5: Low Pressure System
- machine should be turned off during this step
1. test the suction bulb by occluding the connector end with your thumb and making sure the bulb stays deflated after squeezing it
2. Open the common auxiliary gas outlet switch
3. Connect the test suction bulb to the common gas outlet
4. Once test suction bulb is connected, squeeze the bulb several times and make sure it stays deflated for 10 secs
5. Open the vaporizers one at a time and verify the bulb stays deflated for at least 10 secs while each is on (if inflates; there’s a leak)
6. Make sure only one vaporizer can be opened at a time
7.
Step 4: Wall supply
- Reattach the wall supply to verify it is 50psi
Step 5: Low Pressure System
- machine should be turned off during this step
- test the suction bulb by occluding the connector end with your thumb and making sure the bulb stays deflated after squeezing it
