Sol 1-13 DLCO, Alarm, Fan
A Insp/Cal Sample
Switches between inspire port on back of module (unchecked) and Calibration port on
the front of the module (checked)
B Dil/Cal Sample
Switches between the mixing chamber (unchecked) and the calibration port on the
front of the module (checked)
C Hi/Lo Sample Used for calibration. Used to determine the pressure effects on the O2 sensor
D Venturi Forces evacuation of the balloon valves
E Gas Port Inflates the left balloon valve when checked
F Spir Port Inflates the right balloon valve when checked
G Valve Enable
Allows for E and F to work, when balloons inflated and G is disabled the balloons
should stay inflated
H Cal 2 Turns on cal 2 gas
I Cal 1 Turns on cal 1 gas
J DL/O2 Cal
If checked and DLCO (L) is checked, then DLCO gas will be sent through the
calibration circuit. If checked and DLCO (L) is unchecked then O2 gas will be sent
through the calibration circuit.
K Purge Flushes the breathing hose (22 mm) with either O2 or DLCO gas (if L is checked)
L DLCO Unchecked supplies oxygen as the test gas. Checked supplies DLCO as the test gas.
M Alarm Turns on the mixing chamber alarm
N Fan Turns on the mixing chamber fan
