BeneVision N Series Patient Monitor Operator’s Manual 24 - 3
If only one anesthetic agent is used, the AA waveform area displays the waveform of this anesthetic agent. If
several anesthetic agents are used, the AA waveform area displays the waveform of the primary anesthetic
agent.
24.5 AG Equipment to Patient Connection
24.6 Preparing for AG Monitoring
To prepare to monitor AG, follow this procedure:
1. Select the appropriate gas sample line and watertrap according to the patient category.
2. Connect the watertrap to the AG module, and connect the gas sample line to the watertrap.
3. Connect the other end of the gas sample line to the patient via the airway adapter.
4. Connect the gas outlet to a scavenging system using an exhaust tube.
5. Check that the connections are tight.
After the AG module is connected to the SMR, the AG module enters the measurement mode by default and the
monitor prompts AG Starting. AG measurement is available after the start-up is completed.
• Connect the gas outlet to the scavenging system when using the AG module.
• Make sure that the connections are tight. Any leak in the system can result in erroneous readings
due to ambient air mixing with patient gases.
• Always inspect the airway adapter for a tight connection and proper operation before attaching it to
the patient.
• Squeezing or bending the gas sample line during AG measurement may cause erroneous readings
or no readings.
• Position the airway adapter so that the part connecting to the gas sample line is pointing upwards.
This prevents condensed water from passing into the gas sample line and causing an occlusion.
