5.1 Introduction
The SERVO-s Ventilator System can operate
in several different modes. This chapter
describes the modes, their settings, and
associated safety information.
It also summarizes special ventilatory
functions, backup ventilation, and breathing
parameters.
See the Technical data chapter for default
values and allowed ranges for the breathing
parameters.
Note:
The SERVO-s Ventilator System is delivered
preset with the following configuration
options:
• Breathing parameters are based on either
Minute Volume or Tidal Volume.
• Breathing parameters are based on either
I:E Ratio or Inspiration Time.
5.1.1 Warnings
Note: Not all warnings apply to all modes.
WARNINGS!
• Be sure to set alarm limits as appropriate
for each mode. It is especially
- Minute Volume Alarm
- Apnea time
• Self-triggering should be avoided. Do not
set the trigger sensitivity too high.
• To protect the patient’s lungs from
excessive pressure it is important to set
the upper pressure limit to a suitable
value.
• The following warnings apply to Non
Invasive Ventilation (NIV) only:
- Avoid high inspiratory pressure as it
may lead to gastric overdistention and
risk of aspiration. It may also cause
excessive leakage.
- Use of the Nebulizer is not
recommended.
• Ensure that PRVC, SIMV (PRVC) and VS
function properly (especially for small
patients):
- Avoid leakage (e.g. due to an uncuffed
endotracheal tube).
- If compliance compensation is used,
make sure that the compressible
volume of the patient circuit is not
changed after the Pre-use check /
Patient Circuit Test has been
performed (e.g. filling an active
humidifier with water after the test has
been made).
