Distribution And Regulation Of Medical Gases

Front 1

sets structural standards for central piping systems

Back 1

National Fire protection agency

Front 2

ASSS

Back 2

1) provides standards for high pressure connections between large compressed gas cylinders
2)thread diameter, handedness of threads, external of internal threading determine a given connection

Front 3

PISS

Back 3

1) for cylindern sizes up through and including "E"
2)yoke type connection
3)six different pin positions--each gas uses a different combination of two of the six

Front 4

DISS

Back 4

1) Low pressure safety system (less than 200 psig)
2)Thread dimensiobns are varied
3) ex--inlets of blenders, flowmeters, ventilators

Front 5

KISS

Back 5

1)Many different manufacturers of these system. Each is unique, and thus they are not compatible with each other
2)Each gas has a different shaped connector
3)Also called quick connect

Front 6

Regulator

Back 6

regulates both flow and pressure

Front 7

Bourdon gauge

Back 7

-outlet is of a fixed orifice size, so this device requires an adjustable pressure reducer
2)reads flow but measures pressure

Front 8

Thorpe flowmeters

Back 8

1)Always attached to a 50 psig source
2)outlet size is adjustable
3)truly measures flow
4)compensated will read accurately in the event of a downstream obstruction

Front 9

Large air compressors

Back 9

1)has cooler to dry out the air
2)pressure has to be regulated down to 50 psig

Front 10

Blenders

Back 10

combine 50 psis of air and 50 psis of oxygen
