Capnograph and Ventilator
Revision C, August 2013
14-5
PC-sam main display
The PC-sam main display is shown on the next page configured with ECG, capnograph,
ventilator and temperature.
The CO
2
waveform from the capnograph is displayed along with the respiration rate,
respiration period, CO
2
gate, end-tidal CO
2
and minimally inspired CO
2
. The CO2
waveform can be displayed in %, mmHg or kPa. The microCapStar measures the CO2
as a % and sends the value to the Capnograph/Ventilator Interface Module where the
current atmospheric pressure is measured and used to make the conversion to mmHg
or kPa.
Note that the CO
2
gate is delayed by several seconds relative to the breathing of the
animal. The delay is due to the long length of tubing. As a result, the CO
2
gate should
not be used for respiratory gating. Instead use P-resp or E-resp. when performing
respiratory gating.
