Off initially, then th test should be repeated as each vaporizer is turned on During the low pressure leak test the vaporizers should be in what position? The breathing circuit and entire low pressure system
What does the high pressure leak test on the anesthesia machine with NO check valve? The breathing circuit and low pressure system up to check valve only.
What does the high pressure leak test on the anesthesia machine with check valve?
Closing the APL valve and pressurizing the system to 30cm/H2O, while observing the airway pressure gauge for a constant pressure.
How does one perform a High pressure leak test on the anesthesia machine? Closed
When the check valve is in the prescence of back pressure it is considered to be open or closed? Open
In the anesthesia machine the absence of back pressure means the check valve is considered to be open or closed?
a description of the architecture of the anesthesia machine that details the path gases flow from anesthesia suite, through machine and breathing circuit.
