SEE High-Yield Anesthesia Machine,
Equipment, Monitors Questions with
100% Correct Answers
What is the pressure of the high pressure cylinder system? Correct Answer:
Whatever the PSI of the cylinder is. Gets down-regulated at first-stage regulator
What is the pressure of the pipeline pressure? What about tank pressure?
Implication? Correct Answer: Pipeline = 50psi
Tank = 45psi
Pipeline is slightly higher, such that the anesthesia machine will naturally
preferentially draw supply from pipeline, such that O2 tank is not utilized until
there is a supply failure
What is the pressure of the low pressure system such as the flowmeter,
vaporizers, common gas outlet? Correct Answer: Slightly above atmospheric
What components comprise the intermediate pressure system? Correct Answer:
Pipeline pressure, oxygen pressure failure sensor, oxygen second=stage
regulator, oxygen flush valve, ventilator power inlet
What components comprise the high pressure system? Correct Answer: Basically
just the cylinder and associated regulators and gauges
What is the SPDD model for anesthesia gas delivery to the patient? Correct
Answer: Supply, Processing, Delivery, Disposal
,What is the supply component of the SPDD model? Correct Answer: How the
gas enters the anesthesia machine such as the pipeline or tank
What is the processing component of the SPDD model? Correct Answer: How
the anesthesia machine prepares the gases before delivery to the patient such
as flowmeters and vaporizers
What is the delivery component of the SPDD model? Correct Answer: How the
prepared gases are brought to the patient such as the breathing circuit
What is the disposal component of the SPDD model? Correct Answer: How the
waste gases are gotten rid of, such as the scavenging system
What is the Pin Index Safety System? Correct Answer: Prevents inadvertent
misconnections of gas cylinders to the anesthesia machine
What does the pressure change from the cylinder to intermediate pressure?
Correct Answer: Whatever the PSI of the tank is to 45-50psi
What is the PISS configuration for air? Correct Answer: 1, 5
What is the PISS configuration for O2? Correct Answer: 2, 5
What is the PISS configuration for N2O? Correct Answer: 3, 5
What is full air tank PSI and Liters? Correct Answer: PSI = 1900
L = 625
What is full oxygen tank PSI and Liters? Correct Answer: PSI = 1900
, L = 660
What is full N2O tank PSI and Liters? Correct Answer: PSI = 745
L = 1590
What is the formula for determining how much time is left in oxygen cylinder
based on current cylinder PSI? Correct Answer: Take the known values such as
full tank PSI, liters, and current PSI and do the math to find out current liters left.
Once the amount of liters left is known, divide that value by the current liter flow
rate
Why does N2O exist as a liquid within the cylinder? Implication? Correct Answer:
Because it's critical temperature is above room temperature. This means that
you cannot determine the remaining capacity of N2O based on PSI, but only by
weight. Lastly, once the PSI gauge starts to fall below 745psi, this typically
indicates that the N2O tank is 3/4 empty
What is the oxygen pressure failure device? What is the limitation? Correct
Answer: This notifies the anesthetist that the oxygen pressure is decreasing in the
anesthesia machine via decreased pipeline or cylinder supply. Limitation is that
this only senses PRESSURE, not actual FiO2 content!
What is the annular space in regards to a flowmeter? Correct Answer: This is the
space between the float and the side of the flowmeter
What is the only type of flowmeter float that is read in the middle? Correct
Answer: Ball
