Preoperative Tests Preoperative Checklist
5.2 Preoperative Checklist
5.2.1 Introduction
The purpose of preoperative check is to detect potential system problems before use.
An effective method for detecting pneumatic circuit occlusions, leaks, and other system problems
can be found in the procedures of preoperative checks. In addition, it is recommended that the
breathing circuit be tested for the ability to effectively deliver positive pressure ventilation before
each ventilation begins. Test to see if the test lung can be properly ventilated and quickly identify an
occluded circuit limb and other breathing circuit problems.
5.2.2 Suggested Preoperative Checklist
WARNING: To ensure the normal operation of the system and the safety of both the user and the
patient, please follow all check procedures established by the hospital before
administering anesthesia to the patient.
Each day before administering anesthesia, the following should be done:
1. With the anesthesia system connected to an AC power supply, turn on the power switch and
verify that the system is powered by the AC power supply. Follow the on-screen prompts to
perform and complete the start-up test.
2. a. Check the O
2
Supply Failure safety messages and alarms.
(See "O
2
Pipeline Test" on Pages 5-7)
b. Test low O
2
concentration alarms.
(See "O
2
Concentration Monitoring and Alarm Test" on Pages 5-14)
c. Test high and low airway pressure alarms.
(See "Airway Pressure (Paw) Too High Alarm Test" on Pages 5-16)
(See "Airway Pressure (Paw) Too Low Alarm Test" on Pages 5-16)
d. Test low minute ventilation and apnea alarms.
(See "Minute Volume (MV) Too Low Alarm Test" on Pages 5-15)
(See "Apnea Alarm Test" on Pages 5-15)
3. Verify that the O
2
sensor displays approximately 21% in room air and above 94% after exposure
to 100% O
2
(See "O
2
Concentration Monitoring and Alarm Test" on Pages 5-14).
4. Check that the vaporizers are properly installed and sufficiently filled and that filler ports are tightly
closed. Verify that only one vaporizer can be turned ON at a time("Vaporizer" on Pages 3-4.).
5. Perform a vaporizer leak test for each vaporizer installed on the equipment(See "Vaporizer Leak
Test" on Pages 5-12).
6. For an anesthesia system equipped with an AGSS, check whether the AGSS float position is
between the Min and Max scale lines ("Inspect the AGSS" on Pages 5-17).
7. Drain any moisture from the breathing system water trap.
8. Drain and wipe with a soft cloth any moisture from the absorber canister assembly.
