5. Set other parameters in the same way.
6. Select [ Ok ] when parameter setup is completed.
Follow these steps to set up ventilation parameters:
1. In the parameter setup quick key field, select the ventilation parameter to be set.
2. Push the control knob and turn it to set the selected parameter to the appropriate value.
3. Push the control knob to confirm the setting.
4. Set other parameters in the same way.
6.7.2 Apnea Ventilation
Apnea ventilation is a reserve ventilation mode initiated when the ventilator detects patient
apnea in CPAP/PSV, V-SIMV, P-SIMV, DuoLevel, and APRV modes.
Apnea ventilation can exit only when:
 Patient’s spontaneous breathing has been detected for two continuous times,
 Ventilation mode has been confirmed again,
 Ventilation mode is swapped,
 The Alarm Reset key is depressed,

Apnea ventilation is turned off.
Apnea ventilation the ventilator provides is manifested differently subject to the ventilation
mode for the purpose of matching the doctor’s ventilation strategy to the maximum.
In the SIMV mode, if patient apnea occurs, the ventilator ventilates the patient at the apnea
ventilation frequency in place of the previous SIMV frequency (while other parameter
settings are kept unchanged). During apnea ventilation, same to the previous SIMV mode, the
ventilator allows patient spontaneous breathing or trigger to support ventilation. In the SIMV
mode, apnea ventilation can be turned off by setting the apnea ventilation switch. When
apnea ventilation is turned off, the message “Apnea Vent Off” is displayed in the prompt
message field all the time.
In the CPAP/PSV, DuoLevel or APRV mode, if patient apnea occurs, the ventilator applies
pressure control ventilation at the preset apnea pressure and ensures that the actual breathing
frequency is not lower than the preset apnea ventilation frequency. During apnea ventilation,
the ventilator still allows patient spontaneous breathing or trigger to support ventilation. If
patient spontaneous breathing does not occur any longer, the actual breathing frequency is
equal to the preset apnea ventilation frequency.
