5.3.3 Setting O
2
concentration
312
01-01 13 00
Percentage oxygen set in the fresh gas
mixture. The range of the fresh gas
concentration is 28-100% for O
2
/N
2
O and
21-100% for O
2
/Air.
The O
2
flow can never be less than 200 ml/min
for any patient category. The current O
2
concentration in the gas mix is automatically
adjusted to match this requirement if the fresh
gas flow is decreased sufficiently. In addition,
the O
2
concentration touch pad is highlighted
to inform of this adjustment, and a system
message is displayed for as long as the
limitation is active: 'O
2
lower limit reached'.
Confirming the new fresh gas flow will also
confirm the new O
2
concentration.
