B. If, as in the case of examples (c) and (d) in Table 8-1,
• the minima and maxima identified by the above mentioned black vertical lines and, hence, the
maximal
Lung Impedance
changes are breathing-related,
• the
Plethysmogram
reflects an irregular breathing pattern and/or weak breathing pattern with
cardiac-related
Lung Impedance
changes also being clearly visible,
• breaths are detected frequently to infrequently (respective markers only visible in
BB mode
)
• RRi is available frequently to infrequently, and
• the pa is unlikely to become less regular and/or weaker, then both
time-
based modes
are adequate with TB-I mode being recommended.
C. If, as in the case of examples (e) and (f) in Table 8-1,
• the minima and maxima identified by the above mentioned black vertical lines and, hence, the
maximal
Lung Impedance
changes are not breathing-related,
• the
Plethysmogram
does not reflect a breathing pattern
• breaths are infrequently detected (respective markers only visible in
BB mode
)
• RRi is infrequently available, and
• the pat ng pattern is unlikely to become more regular and/or weaker, then only TB-II
mode is adequate.
NOTE
If in
TB-I mode
the
Stretch Image
(Figure 6-9) or
Silent Spaces Image
(Figure 6-11) every 15 seconds updates in
an apparently arbitrary manner, then it is likely, that the maximal
Lung Impedance
changes being detected
within
Analysis Intervals
are not breathing-related. In this case, consider using
TB-II mode
.
NOTE
Irrespective of the currently selected
Analysis Mode
, the LuMon System in the background permanently
analyzes the measured
EIT raw data
with all
Analysis Modes
and stores or outputs the results obtained with each
mode. The selection of the
Analysis Mode
only determines for which mode the calculated results are displayed
in real time and currently accessible in the trends for review. By selecting a different
Analysis Mode
, it is,
consequently, possible anytime to review the results obtained with other modes in the trends. Should the
selected
Analysis Mode
not have been adequate during a monitoring episode, this feature permits to review
the trend data calculated with another, for the respective monitoring episode, possibly more appropriate
Analysis Mode
.
In order to assess the adequacy of an
Analysis Mode
to review an episode of previously recorded trend data first
review the RRi trend in the corresponding time range. If within the time episode under review RRi is
• frequently available, then all three modes are adequate.
• only available often to rarely or even never,
BB mode
is more and more inadequate, TB-I may be, and
TB-II is adequate. To check whether in this case use of
TB-I mode
is also adequate, open the trend
view stretch area (Figure 6-10) and slowly move one of the flags through the time
episode to be reviewed. If the
Stretch Image
aturized tretch
details view changes in an apparently arbitrary manner when moving the flag, then
TB-I mode
is not
adequate to review the respective episode.
