7.3.4.7 Flow Analysis
fig. 7-16: Flow Analysis
1)
Analysis Window [s]
Time period used by the analysis to determine the baseline.
2)
Min. Signal
Minimum value of the signal (in digit). An artefact will be detected as soon as the signal falls below this
value.
3)
Min. Duration [s]
Minimum duration for an Apnoea or Hypopnoea.
4)
Max. Duration [s]
Maximum acceptable duration for an Apnoea or Hypopnoea.
5)
Apnoea Ratio [%]
The Apnoea ratio
states the fractional flow relative to the baseline. All values below this ratio are
detected as Apnoea.
6)
Hypopnoea Ratio [%]
The Hypopnoea ratio
states the fractional flow relative to
the baseline. All values below this ratio and
above the Apnoea ratio will be detected as Hypopnoea.
7)
Central A: central part [%]
(A: Apnoea)
This value indicates to what extend effort and flow events have to overlap in order to be identified as a
Central Apnoea. For example: If more than 50 % of an Apnoea in the flow channel is overlapped by an
effort event it will be scored as a Central Apnoea.
8)
Mixed A: central part [s]
(A: Apnoea)
Where no central apnoea is detected but an Apnoea and an effort event overlap for at least 4
seconds, a mixed apnoea will be scored.
