CHAPTER 7
Monitoring CO2 (LoFlo Option)
WhenequippedwiththeLoFloCO2option,thepatient’sairwayrespiratorygascanbe
monitored.Thesystemusessidestreammeasurementstoproduce:
•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.
WARNINGS
• 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.
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.
