Start Automatic Ventilation Operations
6 - 20 Operator’s Manual of Anesthesia System
WARNING: Airway pressure and ventilation parameters related to respiration, such
as flow rate, minute ventilation, apnea, are not monitored during
HFNC.
WARNING: An SpO
2
monitoring device should be used to monitor SpO
2
during HFNC.
WARNING: Low gas supply pressure may cause inaccurate O
2
concentration control.
WARNING: Do not use antistatic or conductive breathing tubes. Using tubes made
from such materials will expose the patient to electric shocks and may
cause fires in an oxygen-enriched environment.
WARNING: The equipment must be used under the supervision of professional
medical personnel. If a fault occurs to the equipment or the patient fails
to perform enough spontaneous respiration, professional medical
personnel can give immediate help.
NOTE: Stop the automatic ventilation before starting the HFNC. Otherwise it
may cause inaccurate accuracy of the automatic ventilation or limited
flow adjustment of HFNC.
NOTE: HFNC can be started only when the oxygen supply is connected.
To start the HFNC:
1. Connect the HFNC tube, See "High-flow Nasal Cannula Oxygen (HFNC) Tube" on Pages 3-7.
2. Press the HFNC switch to start the HFNC.
3. Adjust the oxygen concentration and total flow.
4. Press the HFNC switch to close the HFNC after use.

6.8 Start Automatic Ventilation
NOTE: Before starting a new automatic ventilation mode, ensure that all
related ventilation parameters are set appropriately.
NOTE: Close the HFNC before starting the automatic ventilation to avoid
affecting the accuracy of the automatic ventilation.
