Respiration measurement description

When starting respiration monitoring, the system "learns" the patient's respiration
pattern. The respiration rate is calculated from impedance changes and a respiration
waveform is displayed.
Eight breaths are averaged and the average amplitude of the respiration waveform
is found. Detection sensitivity is automatically set at 40% of the average amplitude.
Once learning is complete, the user can adjust the detection sensitivity to 10, 20,
30, 40, 50, 60, 70, 80, or 90%.

How to interpret the respiration values

The following is an example of a regular and even respiratory waveform, with the
inspiration and expiration markers identified (1 = inspiration marker, 2 = expiration
marker).
NOTE

Respiration troubleshooting

Problem
What can I do if the respiration measurement fails?
Why does the waveform have a combination of
shallow and deep breaths, but the monitor is not
detecting the shallow breaths?
2094480-001
The inspiration and expiration markers are only present on the
waveform if they are turned on in the respiration parameter
settings.
Solution
Relearn respiration.
●
Check electrode quality and positioning.
●
Adjust the breath detection sensitivity. During
●
ventilator-supported breathing, the respiration
calculation may count only ventilator-produced
inspirations and expirations.
Other electrical devices may interfere with the
●
measurement.
If the detection sensitivity threshold is set too high,
shallow breaths will not be detected, as shown in
the following example of incorrect detection, where
the 1's indicate breaths, but only the breath with the
inspiration and expiration markers was counted (1
= breath).
Decrease the detection sensitivity percentage until
●
the markers correctly identify each inspiration
and expiration. The following is an example of
correct detection, as indicated by the inspiration
and expiration markers on each breath.
