7.3.3.4 Position Analysis
fig. 7-9: Position Analysis
Analysis Window [s]
The size of the time window, in which the dominant body position is determined.
It is possible to change the classification of body position dependent on the attachment of the
SOMNOwatch
™ plus.
7.3.3.5 SpO
2
Analysis
fig. 7-10: SpO
2
Analysis
1)
Max. Desaturation Time [s]
Maximum duration of a desaturation event.
2)
Min. Desaturation Time [s]
Minimum duration of a desaturation event.
3)
Desaturation [% SpO
2
]
The minimum decrease in SpO
2
for a desaturation event to be detected.
4)
Max. Drop (Artefact) [% SpO
2
per s]
An artefact will be detected if desaturation decreases faster than this predefined value.
5)
Oscillation Range [% SpO
2
]
A new desaturation will be scored if this predefined value is exceeded.
fig. 7-11: SpO2 Analysis Oscillation Range (OR)
6)
Min. SpO
2
(Artefact) [%]
If SpO
2
is smaller than this defined value, an artefact is detected.
