1. Easy using Covidair S/T
Switching the device ON
The COVIDAIR device starts up as soon as the external power supply is connected The push button
flashes slowly (1 Hz) to signify that the device has started
If the device has been switched off displaying the graphical interface and the mains supply has
not been disconnected, press the push button to start it again
The device is ready to use when the touch screen displays the main screen The turbine blows at
idle (0 5l/s) to indicate that it is working properly
NOTE:
The display needs about 30 seconds to turn itself on
2.2. Switching the device OFF
To switch off the COVIDAIR device, press the button on the main screen A message will ask for
confirmation of the action The push button flashes quickly (5 Hz) to indicate that the device has

2.3. Start and Sto ventilation
Start and stop via the Touchscreen:
Press the button to start ventilation
The ventilation starts with the parameters saved in the "Parameters" and "Alarms" tabs
The message "Ventilation activated" is displayed and the main button flashes each
time the patient breathes
Press the button to stop the ventilation, a message then asks for
confirmation of the stop and the message "Ventilation stopped" is displayed
Start via the main push button:
Press the main push button to start ventilation
The ventilation starts with the parameters saved in the "Parameters" and "Alarms" tabs
The message "Ventilation activated" is displayed and the main button flashes each time the
patient breathes
Press the main push button again to stop the ventilation, a message then asks for
confirmation of the stop The message "Ventilation stopped" is displayed
NOTE:
The ventilation start function using the main button works even if the device screen has not yet
started It is therefore possible to start ventilation quickly with the last parameters saved!

password 0000
WARNING
The adjustment and modification of the parameters must be carried out under the supervision of
a doctor or a member of the medical profession trained in ventilation
1 Setting the minimum respiratory rate per minute imposed on the patient The value of
the respiratory rate is between 3 and 30 with steps of 1 breath per minute
2 Adjustment of the EPAP expiratory pressure in cmH
2
O The value of the expiratory
pressure is between 2 and 40 cmH
2
O it 1 cmH
2
O increments, but it cannot be greater than
the IPAP value If IPAP and EPAP are equal the device functions as CPAP
3 Adjustment of the IPAP inspiratory pressure in cmH
2
O
4 Tidal volume adjustment WARNING: This value did not take care of leaks It is not
recommended to use this value for ventilation system with leak
The tidal volume value is between 200 and 4000 milliliters with 50ml increments
5 Tidal volume activation slider (see its meaning and use at the end of the chapter)
6 Respiratory Rate adjustment in % The end of the inspiratory cycle is reached when the
flow rate drops to X % of the peak flow rate This value can be set between 15% and 99%
in 1% increments
