NOTE
Nebulization is disabled in V-A/C, V-SIMV, PRVC-SIMV, AMV and PRVC modes
when patient type is pediatric.
When O
2
supply type is low-pressure, pressing the [Nebulizer] key will not activate
nebulizer, rather display the prompt message [Fail to Start with Low Pressure O
2
Supply].
Aerosolized medication may occlude the expiration valve and flow sensor. Please
have them checked and cleaned after nebulization.
Nebulization may cause fluctuation in the patient’s FiO

.
The ventilator switches off the nebulizer flow when the inspiratory flow is less than
15 L/min.
9.5 O

↑(O
2
enrichment)
O
2
↑ is also called as O
2
enrichment. It means to deliver oxygen with concentration higher
than normal level within the specified time period. In the adult patient group, the O
2
enrichment function delivers 100 % oxygen. In the pediatric patient group, the O
2
enrichment
function delivers 1.25 times of the current oxygen concentration or 100 %, whichever is less.
Press the [O
2
↑ Suction] key and the ventilator starts oxygen enrichment. The indicator light
for [O
2
↑ Suction] key is illuminated and the remaining oxygen enrichment time is
displayed in the prompt message field. Oxygen enrichment is active for maximum two
minutes. During oxygen enrichment, the currently set oxygen concentration is displayed in
the [O
2
%] parameter setup quick key field.
When the 2-minute period of oxygen enrichment is up or the [O
2
↑ Suction] key is pressed
again, the ventilator terminates oxygen enrichment.
NOTE
O
2
↑(oxygen enrichment) is disabled in Standby status.
When O
2
supply type is low-pressure, pressing the [O
2
↑ Suction] key will not
activate oxygen enrichment, rather display the prompt message [Fail to Start with
Low Pressure O
2
Supply].
Removing the patient tubing during oxygen enrichment will start suction function.
