3.1.3 Nitrous
Oxide
Blocking
If pressure of oxygen further decreases to approximately 2 bar,the portion
of N
2
O is also reduced proportionally to the portion of oxygen. In case of
a total failure of oxygen supply, the flow of N
2
O is reduced to zero.
The readiness for service of the apparatus can only be restored by
providing the prescribed pressure of oxygen of at least 2 bar at the
connection with the supply system.
