Problem Probable Cause Solution
Respiration
Respiration lead not
selected correctly Check monitor respiration-lead detection and
switch accordingly on the MPS450.
Leads not connected
properly Verify that the color code is correct for U.S.
or International ECG leads.
No respiration signal
Performance waveform
currently output (which
turns off respiration) Select normal physiological waveform.
Temperature
No temperature reading
Wrong series
temperature cable used Check manufacturer’s series for thermistor
used. Choose the correct Fluke Biomedical
temperature cable for 700 or 400 Series.
Cardiac Output
Selected Injectate
temperature not set
correctly Injectate temperature must match expected
temperature: 24
° C or 0 ° C. Use optional
cardiac-output box for setting injectate
temperature.
Incorrect setting for
injectate volume on
cardiac output computer Set to 10 cc.
Incorrect setting for
catheter size on cardiac
output computer Set to 7f.
Expected values not correct, or
no values
Correct constant not set
on monitor Set correct constant to .542 or .595. See
chapter on Cardiac Output.
Injectate temperature not
displayed on monitor Turn on injectate-temperature pot. (Zero the
box until reading displayed is 0
° C or 24 ° C.)
