full range of the flowmeter? ___ (Y)
6.10.2.2
Set the Oxygen-Helium flow to 2 l/min.
6.10.2.3
*
After the value stabilizes, is the O
2
concentration 72 to 78%?
___ (Y)
6.10.2.4
Close the Oxygen-Helium flow valve.
6.10.2.5
Is the correct flow control knob and label attached to the
Oxygen-Helium flow control valve? ___ (Y)
*
Oxygen-Helium specifications are given @ 25% O
2
. Cylinder content
deviations will affect this value. The expected concentration values can be
obtained by replacing the ‘25’ % O
2
value given for O
2
-HE with the actual
cylinder content as follows:
(2 l/min O
2
-HE x ‘25’) + (4 l/min. O
2
x 100 )
6 l/min - Total Flow
=% O
