↑, O
2
concentration for adult patients is 100% and that for pediatric
patients is 1.25 times of the currently set O
2
concentration or 100%, whichever is
less.
Suction Phase 1: O

lasts for a maximum of 120 s.
O
2
concentration for adult patients is 100% and that for pediatric patients is 1.25
times of the currently set O
2
concentration or 100%, whichever is less. When
patient disconnection is detected, the system enters next phase automatically.
Phase 2: suction. Suction lasts for a maximum of 120s. When patient
reconnection is detected, the system enters next phase automatically.
Phase 3: O
2
↑after suction. Delivering 100% O
2
lasts for a maximum of 120s.
O

concentration for adult patients is 100% and that for pediatric patients is 1.25
times of the currently set O
2
concentration or 100%, whichever is less.
Nebulizer Supports jet nebulizer;
Supports to set nebulizer time ranging from 1 to 60 min.
Manual Breath One breath is delivered in the expiratory stage.
Manual breath is not responded if one breath is delivered in the inspiratory stage
or when the expiratory stage is not finished.
P0.1 The pressure drop in the first 100 ms when the patient starts spontaneous
breathing.
