-
What is psig?
pounds per square inch gauge - the difference between measured pressure and surrounding atmospheric pressure
-
What 4 gases are non-liquefied at room temp?
O2, N2, helium, air
-
What 2 gases will partially enter a liquid state at room air?
CO2 and N2O
-
What is a cryogenic liquid?
a gas that becomes a liquid at an extremely reduced temperature
-
What is the critical temp for O2 and the corresponding pressure?
-
What is required of a hospital regarding supply of gas?
They must have a full day of backup supply either in liquid stand tank or cylinder gas manifold
-
What is the critical temp for N2O?
36.5 C
-
What is the capacity of and O2 E cylinder?

625 - 700 Liters
-
What is the capacity of a N2O E cylinder?
1590 Liters
-
Does the pressure within an E cylinder of N2O tell you what volume is remaining?
No - because liquid n2o is continuous being converted into gaseous n2o the pressure will remain elevated until the liquid supply has been depleted
-
Does the pressure in an E cylinder of O2 tell you what volume is remaining?
Yes - because ALL contents are in vapor state
