In PRVC mode, you need to set the following ventilation parameters:

1. [O

%]: Oxygen concentration

2. [TV]: Tidal volume

3. [Tinsp] or [I:E]: Inspiration time or ratio of inspiratory time to expiratory

time

4. [f]: Breathing frequency

5 [PEEP]: Positive end-expiratory pressure

6. [Assist]: Switching trigger ON/OFF

7. [F-Trig] or [P-Trig]: Inspiration trigger level

8. [Tslope]: Time of pressure rising

In PRVC mode, you can set the following sigh function parameters as required:

1. [Sigh]: Switch for turning on sigh function

2. [Interval]: Time interval between two sighs

3. [Cycles Sigh]: Number of sigh cycles

4. [△int.PEEP]: PEEP added in sigh cycle

6.5.9 PRVC-SIMV

PRVC-SIMV is pressure regulated volume control -synchronized intermittent mandatory

ventilation mode. It provides the minimum number of mandatory breaths based on the preset

intermittent mandatory ventilation frequency. The provided mechanical ventilation mode is

volume mode (PRVC mode). If patient triggers within the trigger window, ventilator delivers

mandatory PRVC breath once. Mandatory PRVC breath is also delivered once if it is not

triggered at the end of trigger window. Spontaneous breathing or pressure support breathing

is supported outside the trigger window.

Trigger window is a period of buffer time for patient’s synchronization inspiration. The

period is in the later expiration phase of the mechanical ventilation. The trigger window is 5 s

long for adult and 1.5 s long for pediatric while simultaneously it cannot exceed the

expiratory time.
