6.4 Standby Mode
Standby Mode is the operating mode in which all the systems functionality are idle. It is the default
system startup operating mode and is used between ventilation operations. During Standby, the
user can adjust some settings in any ventilation mode, but no ventilation mode is enabled.
6.4.1 To Enter Standby Mode
:
1.
Select the
Standby key
on the front panel. A confirmation dialog box opens.
2.
Select
Accept
to confirm entering
Standby
mode.
NOTE: In Standby mode, automatic ventilation and parameter monitoring are disabled.
6.4.2 To Exit Standby Mode
:
Push the
start ventilation

6.5 Set Ventilation Mode
6.5.1 Volume Control Ventilation (VCV)
6.5.1.1
Description
Volume control ventilation ( referred to as VCV) mode is a basic fully-mechanical
ventilation mode. In the VCV mode, ventilator delivers the preset tidal volume with a constant flow
or decelerating flow(depending on flow pattern setting)during the preset inspiratory time with the
preset pause time and at the preset respiratory rate.
The peak pressure can vary from breath to breath if the patient's compliance and/or resistance
change.
In the VCV mode, as long as airway pressure is less than upper pressure limit and the gas flow
will be delivered.
To ensure the set tidal volume gas delivery, the ventilator adjusts gas flow based on the
measured inspiratory volume, dynamically compensates for the loss of tidal volume arising
from breathing system compliance and system leakage and eliminates the effect of fresh gas
as well.
