the right midaxillary and the left lateral chest areas at the patient’s maximum point of the breathing
movement to optimize the respiratory waveform.
• To optimize the 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 the electrode application site to ensure skin quality. If the skin quality changes,
replace the electrodes or change the application site.
• Store the electrodes at room temperature. Open the electrode package immediately prior to use.
• Check that the electrode packages are intact and not expired. Make sure the electrode gel is moist.
12.5 Changing Resp Settings
12.5.1 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 menu.
2. Select the
Alarm tab.
3. Set the following alarm properties:
â—† Switch on or switch off the RR alarm and apnea alarm.
â—† Adjust RR alarm limits and priority.
â—† Switch on or switch off the RR alarm and apnea alarm recording.
â—† Set the apnea delay time.
12.5.2 Setting the RR Source
To set RR source, follow this procedure:
1. Select the Resp numeric area or waveform area to enter the
Resp menu.
2. Select the
Setup tab.
3. Choose
RR Source from the dropdown list.
When you select
Auto, the system automatically selects the RR source according to the priority. The priority of
RR source is first CO
2
, and then RM, and finally ECG. When the current RR source does not have valid
measurement, the system automatically switches the
RR Source to Auto.
12.5.3 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 menu.
2. Select the
Setup tab.
3. Set
Resp Lead.
If you cannot get optimal Resp waveform or you suspect the Resp value after choosing the Resp lead, you may
need to optimize the electrode placement.
