ml.
The value of the VT parameter is displayed in the lower part
of the OSIRIS 3 screen.
When we switch from VAC/ACMV 100% O2 mode to
VAC/ACMV Air + O2, the current volume of the instruction
displayed on the screen is slightly modified.Therefore, the
position of the settings button must be adjusted when we
switch from one mode to another.
Setting the PEEP (Positive End Expiratory Pres-
sure)
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
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
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
stored by OSIRIS 3.
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
To inhibit the inspiratory trigger, you need to set it to OFF
(beyond the value « –4 cmH2O »).
With a zero PEEP, the recommended trigger value is
–1.5 cmH2O, this allows better triggering.
The Pmin threshold is set above the PEEP level. E.g.:
for a PEEP of 5 cmH2O and a Pmin threshold of 10 cmH2O,
the alarm will be triggered if the pressure in the circuit does
not exceed 15 cmH2O.
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
cmH O, I/E = ½, RRmax = 40 bpm, Pmin = 5 cmH
