Preoperative Checklist Periodic Maintenance
2. Per manufacturers’ specifications, turn ON the patient monitors to allow
time for their warm-up (ECG, Blood Pressure, SpO 2 , Gas Monitoring,
etc.).
3. Prepare the Anesthetic Gas Scavenging System (AGSS).
a. Remove the AGSS from the AS3000. While viewing the float, turn the AGSS upside
down to verify whether the float moves freely along its shaft. Replace the float as
necessary. Reconnect the AGSS to the AS3000.
b. Connect the vacuum hose to the vacuum port on the AGSS. Adjust the position of the
float to be between the Min and Max lines by turning its flow adjustment knob
(counterclockwise increases flow, clockwise decreases flow).
c. Drain any moisture from the waste gas hose. Connect the waste gas hose to the
AGSS waste gas port.
4. Verify that:
a. Flow-control valves are off
b. Vaporizers are off
c. Vaporizers are filled.
d. Vaporizer Filler caps are sealed tightly.
5. Check oxygen (O 2) cylinder supply:
a. Disconnect line pressure hoses (if connected) and return the cylinder and line
pressure gauges to zero using O 2 flush valve.
b. Open the O 2 cylinder, and check for pressure.
c. Close the O 2 cylinder and observe the pressure gauge for evidence of high-pressure
leaks.
d. Press the O 2 flush valve to empty the piping.
e. A typical full O 2 cylinder’s pressure is 1900 psi. Replace the cylinder if its pressure
is less than 1000 psi.
f. Reopen the cylinder.
6. Check nitrous oxide (N 2 O) cylinder supply:
a. Disconnect line pressure hoses (if connected) and return the cylinder and line
pressure gauges to zero using the flow control knobs.
b. Open the N 2O cylinder, and check for pressure.
c. Close the N 2 O cylinder and observe the pressure gauge for evidence of highpressure
leaks.
d. A typical full N 2 O cylinder’s pressure is 745 psi. Replace the cylinder if its pressure
is less than 600 psi.
e. Reopen the cylinder.
