Therefore, the position of the settings button must be
adjusted when we switch from one mode to another.
Setting the PEEP (Positive End Expiratory Pressure)
This setting is made by turning the graduated knob
The PEEP is adjustable from 0 to 15 cmH

A mechanical safety device
this knob to avoid any possible setting of PEEP > 10
cmH O. To set a PEEP higher than this value, press on

the metal finger next to the knob.
Setting other ventilation parameters (inspiratory
trigger, I/E ratio, Pmini alarm, Fmaxi alarm)
Press successively on the
of the parameter to be set, on the first line of the screen:
• Inspiratory threshold trigger (TRIG)
• Can be blocked (value = OFF)
• Keeps its value between two « power on" switches
• I/E ratio (I/E)
• Pmini alarm threshold (Pmini)
• High frequency alarm threshold (Fmaxi).
Then set the parameter to the desired value using the
and buttons.
Validate by pressing on the
be stored by OSIRIS 2.
Repeat the operation for each parameter.

The I/E ratio setting directly influences the V
insufflated to the patient. Therefore, after changing the
I/E ratio, it may be necessary to reset the V
inspiratory flowrate setting knob
Setting the Pmaxi safety value
This setting is made by turning the graduated knob
Pmaxi can be set between 10 and 80 cmH
The setting is indicated on the screen by a vertical line.
 Each time the device is switched on the default
values for the settings parameters are used: TRIG = -1
cmH2O, I/E = ½, RRmax = 40 bpm, Pmin = 5 cmH2O
for software version V1.020 or earlier and 10 cmH2O
for software version V1.021 or later. To find out the
software version installed, switch on OSIRIS 2. The
