Appendix 1.6 Description of NIV mode
The NIV mode (NIV - non-invasive ventilation) is spontaneous breathing through a face mask
with the predetermined positive pressure in the airways and the predetermined spontaneous
breaths support. This mode is very similar to CPAP+PS, but there are minor differences - they
are associated with the leakage at non-invasive support:
1. The NIV mode always operates with leakage compensation.
2. FiO
2
is set in the range of 21 - 70 %.
3. The trigger of the spontaneous inspiration is set only by pressure (it is more "rough").
4. Special indicator Facc is used for the mode.
5. In the absence of spontaneous breathing, the ventilator enters APNEA mode. Unlike other
ventilation modes when the doctor can choose the APNEA mode either by pressure or by
volume, in NIV mode APNEA mode operates only by pressure.

[Breathing circuit cali-
bration], measuring the circuit parameters shall always be carried out after circuit change and
autoclaving. This is suitable for any mode, but is especially important for the transition from in-
vasive to non-invasive ventilation and vice versa.
Due to the presence of the leakage model, the ventilator can compensate large leak up to 90
lpm. At the large leakage FiO
2
drop can occur.
To control the size of the leak, the user should turn on its displaying in any of the rectangles of

[Leak]. In the LEAK field two leaks will be displayed: peak leakage at the inspiration and av-
eraged leakage during expiration. Leakage will depend upon the pressure in the inspiratory line,
the degree of fitting of the mask to the patient and/or the number of open ports on the mask.
Using of the mainstream capnometer at NIV is inappropriate, because the expiration can go
through the existing gap in the mask and will not get into the chamber of the mainstream cap-
nometer.
