Capnograph and Ventilator
The diagram above shows connections between the microCapStar and the animal. The
measuring and control module is located outside the magnet room near a waveguide. A
long tubing set is provided to connect to the animal in the magnet bore. Note: it is
important to perform the CO2 calibration with the tubing set which will be used with the
animal.
Capnograph operation
Refer to the MicroCapStar End-Tidal CO2 Analyzer Instruction Manual for detailed
instructions for connecting and using the capnograph.
Capnograph/Ventilator Interface Module
The Capnograph/Ventilator Interface Module sends capnograph and ventilator
measurements to the ERT Control/Gating Module so they can be displayed and
recorded using PC-sam.
The Capnograph/Ventilator Interface Module should be located near the ERT
Control/Gating Module.
OPTION OUT, it does not matter which one, and connect it to the fiber optic port of the
Capnograph/Ventilator Interface Module. Make sure you match the color of the cable
with the color of the driver/receiver port. Use a short fiber optic cable to connect to the
unused ports on the two modules.
There are two input connections for the ventilator:
SYNC IN –
SERIAL IN – which provides tidal volume measurements
There are two inputs for the capnograph:
0-1V – which is used for capnographs having a 0-1V output range
0-10V – which is used for capnographs having a 0-10V output range. The
microCapStar Capnograph uses this input.
The switch between the two capnograph inputs should be positioned to be closest to the
input being used.
Display configuration
To add the capnograph and/or ventilator to the monitor configuration, execute PC-sam
and select the option to "open the MONITOR SETUP window".
indicated in the figure below to activate the capnograph and/or ventilator displays.
14-4
Unplug one of the fiber optic cables from OPTION IN or
which provides measurements for I/E ratio and respiration rate
