5.8 Apnoea CPAP mode
In Apnoea CPAP, the basic CPAP of the CPAP mode is complemented by apnoea monitoring. The apnoea
monitoring system assesses fluctuations in the CPAP pressure course which are caused by the patient’s
respiration and responds to phases in which the patient does not breathe by automatically triggered pushes.
In addition to the setting, action and information options which are non-mode-dependent, such as:
- Flow (chapter 5.3)
-
Oxygen concentration
FiO

(chapter 5.3) and start and discontinuation of the

flush
(chapter 5.5)
- F
insp
(additional push flow) and manual PUSH (chapter 5.4)
- Alarm settings (chapter 5.12)
- Trend graphs (chapter 5.13)
there are special settings for the apnoea mode. Open these apnoea settings by pressing button p in Figure 5-2.
You can then change six parameters. To change a parameter, press the corresponding button to select it, turn
the dial to the desired setting, and press the dial to confirm your selection.

flush . The only purpose of the orange lines is to clarify the
significance of the sensitivity setting as a demarcation between respiration and apnoea. They are not
displayed by the medinCNO ® . Instead, the sensitivity is displayed on the left-hand edge of the CPAP curve as a
pair of arrows (blue).
Warning:
Significant amounts of condensate formation in the tube system must be avoided since, as a result, the
respiratory signal in the CPAP pressure curve will be masked, detection of apnoea phases can be prevented,
and the triggering of pushes can be influenced.

The setting in this field determines the duration of pushes automatically triggered in the event of apnoea, the
backup pushes, and the duration of pushes triggered manually. It can be set to a time between 200 milliseconds
and 2 seconds.
