Monitoring Agents and Gases (AGENT Option)
When equipped with the AGENT option, the patient's level of anesthetic agent gases, oxygen 
(O2), carbon dioxide (CO2), and nitrous oxide (N2O) concentrations can be monitored. An 
anesthetic gas sensor (AGS) system uses infrared spectroscopy combined with digital signal 
processing to quickly and accurately identify gas concentrations. 
WARNING
Whenever a patient is under anesthesia or connected to a ventilator, constant attention by
qualified medical personnel is required.

MR400 Preparation for AGENT Monitoring

When preparing the MR400 for AGENT monitoring, ensure that the waste gas port (see page 1‐
19) has been connected to your facility's gas scavenging system for disposal of sampled and 
calibration gases.
Notes

Operation and Use

When monitoring anesthetic agent gases, the typical operations and possible conditions that can 
arise may result in potential messages requiring your attention. See page 4‐26 for a message 
listing and suggested actions.
Expression MR400 Instructions for Use 
These instructions are for setting up a typical monitoring system. Exact components and set-
up procedure used may vary, depending upon the application. For components added to the
monitoring system, refer to applicable manufacturer's instructions for set up and use.
Never route the waste gas tubing in a location that will allow it to be an obstruction or
stepped on.
