Changing Resp Detection Modes

The Resp detection level can be set either automatically or manually.
To change the resp detection mode, in the
Auto Detection Mode
In Auto Detection Mode, the monitor adjusts the detection level automatically, depending on the wave
height and the presence of cardiac artifact. Note that in Auto Detection Mode,
the detection level (a dotted line) is not displayed on the waveform,
the algorithm expects a heart rate and therefore needs at least 3 electrodes attached to the patient.
Use Auto Detection Mode for situations where:
the respiration rate is not close to the heart rate
breathing is spontaneous, with or without continuous positive airway pressure (CPAP)
patients are ventilated, except patients with Intermittent Mandatory Ventilation (IMV).
Manual Detection Mode
In Manual Detection Mode you must set the Resp detection level.
In the
Resp waveform to determine when the desired level is reached.
Once set, the detection level will not adapt automatically to different respiration depths. It is important
to remember that if the depth of breathing changes, you may need to change the detection level.
Use Manual Detection Mode for situations where:
the respiration rate and the heart rate are close.
patients have Intermittent Mandatory Ventilation.
respiration is weak. Try repositioning the electrodes to improve the signal.
Resp Detection Modes and Cardiac Overlay
In Auto Detection Mode:
If you are monitoring Resp and the ECG is switched off, the monitor cannot compare the ECG and
Resp rates to detect cardiac overlay. The respiration detection level is automatically set higher to
prevent the detection of cardiac overlay as respiration.
In Manual Detection Mode:
Cardiac overlay can in certain situations trigger the respiration counter. This may lead to a false
indication of a high respiration rate or an undetected apnea condition. If you suspect that cardiac
overlay is being registered as breathing activity, raise the detection level above the zone of cardiac
overlay. If the Resp wave is so small that raising the detection level is not possible, you may need to
optimize the electrode placement as described in the section "Lateral Chest Expansion" on page 162.
