Daily Machine Checklist
Check that the anesthetia machine is connected to an oxygen supply that is turned on and has adequate
1.
supply at 50-55 psi.
Check that adequate supplies of other gases, if applicable, (nitrous oxide, air) are available and connected as
2.
appropriate.
Check the operation of the flowmeter(s). Check that each needle valve operates smoothly and that the ball
3.
moves freely within the tube.
Check that each vaporizer is adequately filled with respective agent.
4.
Check the breathing circuit for proper configuration, secure connections.
5.
Check that the scavenging system is properly connected/turned on and does not have too much draw (bag
6.
will be completely deflated if there is too much draw or suction).
If using a ventilator, ensure that it is correctly configured and tubing is securely attached.
7.
Pressure test the machine.
8.
Place bag and Universal F-circuit (rebreathing circuit) on the machine with pop-off valve closed.
a.
Occlude the patient end of the circuit with finger and fill bag with the oxygen flush valve.
b.
NOTE! The oxygen flowmeter should be turned off (the ball should be at the bottom of the Flowtube).
Take pressure to 30 cm H
c.
2
O (centimeters of water) or until the bag is full.
Allow pressure to stabilize.
d.
Pressure should not drop more than 5 cm H
e.
2
O (centimeters of water) in 10 seconds.
NOTE! If it does not hold pressure, dial in oxygen from the flowmeter to compensate for the leak. Use
soapy water solution to locate the leak.
Open pop-off valve and relieve pressure to 10 cm H
f.
2
O (centimeters of water).
Dial in 300cc of oxygen on the flowmeter.
g.
Pressure should begin to rise slowly on the manometer.
