Capnograph and ventilator option
Simulators can have, as an option, outputs to simulate a capnograph and a ventilator.
In that case, in addition to ECG and temperature outputs the simulator will have the
following connections and controls:
SYNC OUT BNC ventilator output for I/E ratio and respiration
rate
SERIAL OUT phono ventilator output for tidal volume
CAP OUT BNC capnograph CO
2
CAP AMPLITUDE pot single turn adjustment 0 – 10% CO
waveform output
TIDAL VOLUME pot single turn adjustment 0 – 100 ml
2
CAL switch 10% cal or normal
OUTPUT SCALE switch set CO
2
output scale to 0 – 1 V or 0 – 10 V
To use the simulator, connect the three outputs to the Capnograph/Ventilator Interface
Module. Set the CAL switch to the normal position. Set the OUTPUT SCALE to agree
with the input chosen on the Capnograph/Ventilator Interface Module.
The respiration rate is controlled from the respiration portion of the simulator. The
respiration width control sets the I/E ratio. The other two parameters end-tidal CO
2
and
tidal volume are set by the pots listed above.
Setting the CAL switch to the 10% CAL position will give a flat line at 10%.
