RESP Monitoring
10-5
When [Auto Threshold Detection] is [On] during Resp Monitoring and ECG Monitoring is [Off], the monitor cannot
compare the heart rate and Resp rates to detect cardiovascular artifact. The respiration detection level is
automatically set higher to prevent the detection of cardiovascular artifact as respiration.
When [Auto Threshold Detection] is [Off], cardiovascular artifact can, in certain situations, trigger the respiration
rate counter. This may lead to a false indication of a high respiration or an undetected zero respiration rate condition.
If users suspect that cardiovascular artifact is being registered as respiratory activity, raise the detection level above
the zone of cardiovascular artifact. If the Resp wave is so small that raising the detection level is not possible, users
may need to optimize the electrode placement.
10.5.9 Manually Adjust Resp Wave Detection Threshold
You may need to manually adjust RESP wave detection threshold in the following situations:
RR is close to HR.
The patient is under intermittent mandatory ventilation (IMV).
Weak breath. Try to relocate the electrode to improve signal quality.
Steps to adjust RESP wave detection threshold are as follows:
1) Select the RESP parameter area or waveform area to enter [Resp] menu.
2) Select [Threshold] tab.
3) Set [Upper Scale] and [Lower Scale].
Once set, the detection level will not automatically adapt to different respiratory depths. Thus, if respiratory depth
changes, you may need to adjust the detection level.
10.6 Enter Intubation Mode
If the currently monitored patient is under the intubation process of a general anesthesia surgery, the monitor can
be set to Intubation Mode to shield unnecessary alarms. Steps for setup are as follows.
1) Select the RESP parameter area or waveform area to enter [Resp] menu.
2) Select [Intubation Mode].

Section7.19 Intubation Mode
