Note
To reduce the risk of hypoxic gas mixtures at very low gas flows, the
O2 fresh gas flow does not go to zero. When O2 flow is displayed as
0 lpm, there may a residual O2 flow of 25 to 125 ml per min.
Note
Different breathing circuit pressures, barometric pressures, or
temperatures change the total flow tube accuracy. During some
conditions, these changes can be larger than specified tolerances.
Note
In the unlikely case of power failure (mains and backup battery) while
the machine is in use, oxygen will continue to flow. The total flow
tube will indicate the total flow of oxygen to the vaporizer and patient
circuit. Manual ventilation is available to complete the case.
Note
When O2, Air or N2O flow is greater than 15 lpm, the display screen
only shows >15 lpm.
