24 - 6 BeneVision N Series Patient Monitor Operator’s Manual
4. Set the speed and scale of gas waveforms. For CO
2
, you can also set Waveform Type.
24.8.6 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 menu.
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.
24.8.7 Entering the Intubation Mode
When performing intubation during general anesthesia, you can enter the intubation mode in order 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 menu.
2. Select Intubation Mode from the bottom of the menu.
For the details of the intubation mode, see 10.13Intubation Mode.
24.8.8 Enabling or Disabling MAC Display
You can set whether MAC value is displayed in the AG numberic area. To do so, follow this procedure:
1. Select the AG numeric area or waveform area to enter the Gas menu.
2. Select the desired anesthetic agent tab.
3. Switch on or off MAC.
24.9 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.
