6.11 NON INVASIVE VENTILATION
6.11.1 NON INVASIVE VENTILATION
This chapter refers to when the SERVO-s
Ventilator System is used during Non Invasive
Ventilation (NIV). NIV refers to ventilation,
where the patient is not intubated or
tracheotomized. It is achieved using a nasal
mask, face mask or full-face mask.
Note: In NIV, flow and pressure curves and
the measured values: VTi, VTe, MVe, MVi
are compensated for leakage.
The NIV disconnect function is available in all
NIV modes and can be set via the
Biomed>Edit startup configuration window.
The setting can be used to ensure a constant
disconnect flow while ventilation is paused
(High flow and Low flow) or as a way to avoid
pausing ventilation in case of high leakage
(Disabled).
For NIV disconnect function settings,
see Functions in ventilation modes on
page 154.

WARNINGS!
Avoid high inspiratory pressure as it may
lead to gastric overdistension and risk of
aspiration. It may also cause excessive
leakage.
The dead space will increase when a
mask is used.
NIV is not intended to be used on
intubated patients.
CO measurement will be affected by
2
mask leakage.
In non-invasive ventilation, the measured
expired volume may be different from the
actual volume exhaled by the patient due
to leakage around the mask.
