O 2 Conserve
Use the O2 Conserve option to minimize the use of oxygen from an O2 source while maintaining the
FIO2 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. O2
Conserve ON reduces trigger sensitivity and should be used when the conservation of oxygen is
necessary.
When CONSERVE OFF is selected, the ventilator provides a bias flow of 10 lpm and automatically
selects flow triggering. O2 Conserve OFF provides the best trigger sensitivity and should be used
when the conservation of oxygen is not a priority.
• The O2 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 O2 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
O2 Conserve – When CONSERVE ON is selected:
• The LTV ® 1200 automatically sets the bias flow to 0 lpm and selects pressure triggering. Certain
patients may experience difficulty triggering a breath with a bias flow of 0 lpm.
• Delivered FIO2 can be lower than the set value when tidal volumes are less than 100 ml.
AVERTISSEMENT
O2 Conserver – Quand “CONSERVE ON” est sélectionné :
• Le LTV 1200 règle automatiquement le flux à 0 lpm et sélectionne le déclencheur de pression.
Certains patients peuvent éprouver des la difficulté à déclencher une respiration avec un flux de 0
l/min.
• Le FI02 peut diminuer la valeur sélectionnée quand le volume courant est de moins de 100 ml.
