Whatever the PSI of the cylinder is. Gets down-regulated at first-stage regulator
What is the pressure of the high pressure
cylinder system?
Pipeline = 50psi
Tank = 45psi
What is the pressure of the pipeline pressure? Pipeline is slightly higher, such that the anesthesia machine will naturally prefere
What about tank pressure? Implication? draw supply from pipeline, such that O2 tank is not utilized until there is a supply
Slightly above atmospheric
What is the pressure of the low pressure
system such as the flowmeter, vaporizers,
common gas outlet?
What components comprise the intermediate Pipeline pressure, oxygen pressure failure sensor, oxygen second=stage regulator
pressure system? flush valve, ventilator power inlet
, Basically just the cylinder and associated regulators and gauges
What components comprise the high pressure
system?
What is the SPDD model for anesthesia gas Supply, Processing, Delivery, Disposal
delivery to the patient?
What is the supply component of the SPDD How the gas enters the anesthesia machine such as the pipeline or tank
model?
How the anesthesia machine prepares the gases before delivery to the patient such
What is the processing component of the
flowmeters and vaporizers
SPDD model?
How the prepared gases are brought to the patient such as the breathing circuit
What is the delivery component of the SPDD
model?
What is the disposal component of the SPDD How the waste gases are gotten rid of, such as the scavenging system
model?
What is the Pin Index Safety System? Prevents inadvertent misconnections of gas cylinders to the anesthesia machine
What does the pressure change from the Whatever the PSI of the tank is to 45-50psi
cylinder to intermediate pressure?
What is the PISS configuration for air? 1, 5
What is the PISS configuration for O2? 2, 5
What is the PISS configuration for N2O? 3, 5
, PSI = 1900
What is full air tank PSI and Liters? L = 625
PSI = 1900
What is full oxygen tank PSI and Liters? L = 660
PSI = 745
What is full N2O tank PSI and Liters? L = 1590
Take the known values such as full tank PSI, liters, and current PSI and do the ma
find out current liters left.
What is the formula for determining how
much time is left in oxygen cylinder based on Once the amount of liters left is known, divide that value by the current liter flow
current cylinder PSI?
Because it's critical temperature is above room temperature. This means that you
determine the remaining capacity of N2O based on PSI, but only by weight. Lastl
Why does N2O exist as a liquid within the the PSI gauge starts to fall below 745psi, this typically indicates that the N2O tan
