11. Perform Leak Check of the Breathing System
A. Set all gas flows to zero (or minimum).
B. Close PRV valve and occlude "Y" piece or install a reservoir bag to distal end of circuit.
C. Pressurize breathing system to about 30 cmH

Flush.
D. Ensure that pressure remains fixed for at least 10 seconds.
E. Open PRV valve and ensure that pressure decreases.
Manual and Automatic Ventilation Systems
12. Test Ventilation Systems and Unidirectional Valves
A. Place a second breathing bag on "Y" piece.
B. Set appropriate ventilator parameters for next patient.
C. Switch to automatic ventilation (ventilator) mode.
D. Fill bellows and breathing bag with O
2
Flush. Turn ventilator power switch to air or O
2
.
E. Set O2 flow to minimum, Air to zero.
F.
Verify that during inspiration, bellows deliver appropriate tidal volume and that during
expiration, bellows fills completely.
G. Set fresh gas flow to approx. 5 L/min.
H. Verify that the ventilator bellows and simulated lungs fill and empty approximately
without sustained pressure at end-expiration.
I. Check for proper action of unidirectional valves located in CO
2
canister.
J. Exercise breathing circuit accessories to ensure proper function.
K. Turn ventilator gas power switch to the "OFF" position and turn bag switch to
"BAG" mode.
L. Ventilate bag manually and assure inflation and deflation of artificial lung and
appropriate feel of system resistance and compliance.
M. Remove second bag from "Y" piece.
N. Turn B/V switch to "Vent". Allow bellows to fill.
O. Set minute volume contro to 8L/min and frequency to 10 B/min.
P.
Utilize a 1 liter breathing bag as a test lung.
Q. Turn on the ventilator to either air or O
2
depending on which gas you will be using to
drive the vent.
