5.11 Non Invasive Ventilation
5.11.1 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 156.
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
2
measurement will be affected by
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.
