What is the full pressure in an oxygen E-Cylinder? 

2200psig 

100
What two gases enter a high-flow blender?

Air and O2

200

What's the purpose of a frangible disk on a gas cylinder?

It ruptures if the pressure inside the cylinder becomes too high 

200

What happens to FiO₂ if total flow is increased but FiO₂ dial stays the same?

FIO2 does not change 

300

Explain what an alternating manifold system does:)

it has a service side and a reserve side 

The service side is set at 50psig and once it empties, it will automatically swicth to the reserve side 

400
1kg of liquid O2 = how many L 

860L

500

Why cant pressure gauge readings show the amount left in N2O cylinder?

it contains a liquid/vapour and the pressure stays constant until the liquid is gone 

500

What happens when the pressure in a belnder drops below 50psig 

Diaphragm shifts, alarm sounds and a blender may deliver more of the higher gas 

inaccurate FIO2
