4. Set the speed and scale of gas waveforms. For CO
2
, set Waveform Type.
17.8.6 Setting the RR Source
To set the RR (respiration rate) source, follow this procedure:
1. Select the AG numeric area or waveform area to enter the
Gas dialog.
2. Select the desired gas tab.
3. Select the
Setup tab.
4. Set
RR Source.
When the current RR source does not have valid measurement, the system will automatically switch
RR Source
to
Auto.
17.8.7 Entering the Intubation Mode
When performing intubation during general anesthesia, enter the intubation mode to reduce unnecessary
alarms. To enter the intubation mode, follow this procedure:
1. Select the AG numeric area or waveform area to enter the
Gas dialog.
2. Select
Intubation Mode from the bottom of the dialog.
For the details of the intubation mode, see
7.13Intubation Mode.
17.8.8 Enabling or Disabling MAC Display
Set whether MAC value is displayed in the AG numeric area by following this procedure:
1. Select the AG numeric area or waveform area to enter the
Gas dialog.
2. Select the desired anesthetic agent tab.
3. Switch on or off
MAC.
17.9 Changing the Anesthetic Agent
When the anesthetic agent used on the patient is changed, the AG module detects the mixed anesthetic gas
during the transition of two anesthetic agents. The time required for completing the replacement of anesthetic
agent depends on anesthesia type (low flow or high flow) and the characteristics of anesthetic agents
(pharmacokinetics). During the transition of two anesthetic agents, the monitor gives no prompt messages and
the MAC value displayed may be inaccurate.
The AG module can identify two anesthetic agents automatically. When the proportion of primary and
secondary anesthetic agents in the mixture changes, the AG module can distinguish between them according to
their contributions to the MAC value. Then primary and secondary anesthetic agents will be exchanged for
display.
17.10 Performing AG Leakage Test
The AG leakage test is required every time before the AG measurement. To perform the AG leakage test, follow
this procedure:
1. Plug the AG module into the module rack.
2. Wait for about one minute until the AG module warms up. Completely block the gas inlet of the AG
module. Then the alarm message “
AG Airway Occluded” will appear on the screen.
3. Block the gas inlet for another one minute.
4. Select the
Main Menu quick key → from the System column select Maintenance → input the required
password
→ select .
5. Select the
Module tab → AG tab.
6. Check that the current flow rate is less than 10 ml/min, and the alarm message “
AG Airway Occluded” does
not disappear.
