When equipped with the LoFlo CO2 option, the patient's airway respiratory gas can be 
monitored. The system uses sidestream measurements to produce: 
WARNINGS
Note
LoFlo option-equipped models do not feature a water trap (see page 7-4). If your MR400 is
equipped with a water trap, refer to chapter 9 for CO2 monitoring instructions.

MR400 Preparation for CO2 Monitoring

When preparing the MR400 for CO2 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.
Note
Never route the waste gas tubing in a location that will allow it to be an obstruction or stepped on.
Expression MR400 Instructions for Use
Monitoring CO2 (LoFlo Option)
A fractional inspired CO2 (FiCO2) value (the lowest reading of the CO2 waveform in the 
previous 20 seconds) and an end‐tidal CO2 (EtCO2) value measured during expiration.
A respiration rate: The number of breaths per minute. 
A waveform of the concentration of carbon dioxide in the respiratory gases.
Do not use on patients that cannot tolerate the withdrawal of 50ml/min ± 10 ml/min
from the airway or patients that cannot tolerate the added dead space to the airway.
An alarm will sound when the MR400 is too close to the MR magnet and shutdown of
CO2 monitoring will occur. Always position the MR400 as indicated on page 3-2.
