O 2 Conserve
Use the O 2 Conserve option to minimize the use of oxygen from an O 2 source while maintaining the
FIO 2 during inspiration.
When CONSERVE ON is selected, the ventilator provides a bias flow of 0 lpm and automatically
selects pressure triggering. Oxygen is supplied during inspiration, but not during expiration. O 2
Conserve ON reduces trigger sensitivity and should be used when the conservation of oxygen is
necessary.
When CONSERVE OFF is selected (and the ventilator is in Flow Sensor patient circuit mode), the
ventilator provides a bias flow of 10 lpm and should be used when the conservation of oxygen is not a
priority.
The O 2 Conserve option is not affected by turning the ventilator on or off. The ventilator retains
the desired setting through power up and power down cycles.
If O 2 Conserve is set to ON, the message BIAS FLO OFF will scroll through the alphanumeric
display when the ventilator is in operation.
To modify the O2 CONSERVE setting:
1) Push the Select button while O2 CONSERVE is displayed.
2) CONSERVE ON or CONSERVE OFF is displayed.
3) Turn the Set Value knob until the desired state is displayed.
4) Push the Select button.
Options: ON or OFF
WARNING
O 2 Conserve – When CONSERVE ON is selected:
The LTV ® 1100 automatically sets the bias flow to 0 lpm and selects pressure triggering. Certain
