CAUTION
• Correct electrode placement can help to reduce interference from cardiac related impedance
changes: avoid including the liver area and the ventricles of the heart between the respiratory
electrodes. This is particularly important for neonates.
• Some patients with restricted movements breathe mainly abdominally. In these cases, you may
need to place the left leg electrode on the left abdomen at the point of maximum abdominal
expansion to optimize the respiratory waveform.
• Some patients (especially neonates) expand their chests laterally, causing a negative intrathoracic
pressure. In these cases, it is better to place the two respiration electrodes in the right midaxillary
and the left lateral chest areas at the patient’s maximum point of the breathing movement to
optimize the impedance respiration waveform.
• To optimize the impedance respiration waveform, place the RA and LA electrodes horizontally when
monitoring respiration with ECG Lead I; place the RA and LL electrodes diagonally when monitoring
respiration with ECG Lead II.
• Periodically inspect electrode application sites to ensure skin integrity. If the skin quality changes,
replace the electrodes or change the application site.
NOTE
• Store the electrodes at room temperature. Open the electrode package immediately prior to use.
• Check that the electrode packages are intact and that the electrodes are not past the expiration
date. Ensure the electrode gel is moist.
10.5 Changing Resp Settings
10.5.1 Setting the Resp Alarm Properties
To set the Resp alarm properties, follow this procedure:
1. Select the Resp numeric area or waveform area to enter the
Resp dialog.
2. Select the
Alarm tab.
3. Enter the password if required. For more information, refer to
25.13.3Selecting Password for User Authentica-
tion
.
4. Set alarm properties as desired.
10.5.2 Setting the RR Source
To set RR source, follow this procedure:
1. Select the Resp numeric area or waveform area to enter the
Resp dialog.
2. Select the
Setup tab.
3. Choose
RR Source from the dropdown list.
When you select
Auto, the monitor automatically selects the RR source following order of priority: first CO2, and
then
ECG. When the manually selected RR source is not available, the monitor automatically switches the RR
Source to Auto.
10.5.3 Choosing the Respiration Lead
To set the respiration lead, follow this procedure:
1. Select the Resp numeric area or waveform area to enter the
Resp dialog.
2. Select the
Setup tab.
3. Set
Resp Lead.
If you cannot get an acceptable impedance Resp waveform or you suspect the veracity of the Resp value after
choosing the Resp lead, you may need to adjust the electrode placement.
