Cardiac Output
Problem:
Why does the monitor continue to display a PLEASE
WAIT or UNSTABLE BT message?
Answer:
The monitor is searching for a stable baseline
temperature. The message clears after 12 seconds, only
if a stable baseline temperature is found.
Intervention:
■ Check the patient and patient setup.
■ Check for the following factors which may influence
the baseline temperature:
• Significant amount of Respiratory Variation.
• Rapid IV Solutions Infusion.
■ Check the injectate temperature (IT). A minimum
temperature difference of 10˚ Celsius is
recommended between the patient blood temperature
and solution temperature.
■ Replace the Injectate Temperature cable.
■ The Swan-Ganz Catheter itself may be damaged.
