Updated: 12.3.2013
The AFT20 connects the CO2100C or O2100C directly to the sampling port of a mixing chamber. The
AFT20 also permits sampling connections to the Non-rebreathing “T” Valves (AFT21 or AFT22).
MRI Use:
MR Safe
AFT20 Gas Sampling Kit Components:
Tubing: 1.8 m of 1.5 mm diameter polyethylene tubing with
M/F Luer; Tubing: 30 cm Nafion
water vapor permeable tubing with M/F Luer connector; Y-
connector: Acrylonitrile butadiene styrene (ABS) polycarbonate
AFT31-MRI
This 3.175 mm ID tubing is 10 meters long with male and female Luer
lock and "Y" connector interfaces to the AFT21 T-valve, AFT25
facemask, or AFT15 mixing chamber gas sampling ports to connect
them to the CO2100C module and/or the O2100C module. To use both
CO2100C and O2100C modules simultaneously, a “Y” connector gas
sampling interface adapter is included.

AFT35-MRI
The Airflow Subject Interface Kit for MRI will allow two configurations with minimal clearance from
mouth to fMRI cage:
Low clearance - 6 cm: use right-angle coupler with mouthpiece and noseclip
Standard clearance - 12 cm: use right-angle coupler with facemask
The AFT35-MRI assembly includes a high-flow, non-rebreathing T valve with right-angle interface to
separate inspired flow from expired flow. Use assembly to perform the following airflow and lung
volume tests in an fMRI:
•
End Tidal CO2
•
VO2 max
•
Breath-by-breath Air Flow
•
Breath-by-breath Volume
•
Metabolic Studies
The subject breathes into a right angle port that connects to the T valve. The inspire port is directly open
to the chamber room, so there is very low inspired resistance, and the T value expired port connects
directly to 35 mm ID tubing (such as AFT7L).
The AFT35-MRI assembly includes a 35 mm OD T valve (AFT23), mouthpiece (AFT9), facemask
with strap, noseclips, right-angle connector, and couplers.
The AFT35-MRI will connect to one or more lengths of AFT7L tubing, for ultimate connection to
AFT15 Gas sampling chambers, as well as a TSD117-MRI air flow transducer.
